此篇文章主要講解如何封裝一個php的用于文件上傳下載的函數(shù)，可以用于本demo中的頭像上傳功能，順便講解一下多文件上傳的方式。如果對于文件上傳特別熟悉可以跳過此節(jié)。
還是使用之前那個界面。

這里是文件目錄:

在表單提交的doAdminAction.php中，只需要增 加move_uploaded_file($_FILES["face"]["tmp_name"], <br> "upload/" . $_FILES["face"]["name"]);這一行代碼，即可把客戶端上傳的文件放在服務(wù)器中的對應(yīng)的地方。但是這樣的代碼有一些問題
(1)如果在admin不存在upload的文件夾，文件上傳不上去。
(2)對于上傳的文件的類型沒有進(jìn)行檢驗,如果出現(xiàn)病毒文件會比較危險。
(3)如果上傳了與upload文件夾中的文件名稱相同的文件，原來的文件就會被替換掉。
(4)對于文件上傳可能會出現(xiàn)的一些錯誤沒有進(jìn)行處理，例如文件大小超過了2M，(php ini 文件中默認(rèn)規(guī)定的上傳限制大小為2M)
下面是解決方案:
(1)首先判斷upload的文件夾是否存在，如果不存在則建立

<code><span>$path</span>=<span>"upload/"</span>;   
<span>//</span>如果路徑不存在就建立的路徑上
    <span>if</span>(!file_exists(<span>$path</span>))
    {
        mkdir(<span>$path</span>,<span>0777</span>,<span>true</span>);
    } </code>

(2)使用strtolower(end(explode(“.”, $filename)));獲得文件的拓展名
然后判斷拓展名是否在所需要的文件類型中。
(3)使用md5(uniqid(microtime(true),true));得到一個唯一的字符串與之前得到的文件拓展名連接在一起，作為上傳文件的文件名。
(4)現(xiàn)在開始編寫doAdminAction的代碼，第四個問題將在代碼中講解。

<code><span><span><?php </span><span>require_once</span><span>'../include.php'</span>;
    <span>//print_r($_FILES["face"]);</span><span>$path</span>=<span>"upload/"</span>;
    <span>//如果路徑不存在就建立的路徑上</span><span>if</span>(!file_exists(<span>$path</span>))

    <span>if</span>(!in_array(<span>$ext</span>,<span>$allowExt</span>)){
        <span>exit</span>(<span>"非法文件類型"</span>);
    }
    <span>//得到了唯一的文件名的文件</span><span>$filename</span>=getUniName().<span>"."</span>.<span>$ext</span>;
    <span>if</span>(move_uploaded_file(<span>$_FILES</span>[<span>"face"</span>][<span>"tmp_name"</span>],
    <span>$path</span>.<span>$filename</span>))
    {
        <span>echo</span><span>"文件上傳成功"</span>;
    }
    <span>else</span>
    {
        <span>switch</span>(<span>$_FILES</span>[<span>"face"</span>][<span>'error'</span>]){
            <span>case</span><span>1</span>:

            <span>case</span><span>4</span>:
                <span>$mes</span>=<span>"沒有文件被上傳"</span>;<span>//UPLOAD_ERR_NO_FILE</span><span>break</span>;
            <span>case</span><span>6</span>:
                <span>$mes</span>=<span>"沒有找到臨時目錄"</span>;<span>//UPLOAD_ERR_NO_TMP_DIR</span><span>break</span>;
            <span>case</span><span>7</span>:

            <span>case</span><span>8</span>:
                <span>$mes</span>=<span>"由于PHP的擴(kuò)展程序中斷了文件上傳"</span>;<span>//UPLOAD_ERR_EXTENSION</span><span>break</span>;
        }
        <span>echo</span><span>$mes</span>;
    }
<span>?></span></span></span></code>

如果發(fā)生了出現(xiàn)的錯誤，則這些錯誤會被打印出來。至此單文件上傳的內(nèi)容講解完畢，現(xiàn)在將上述的代碼封裝為函數(shù)。

<code><span><?php </span><span><span>function</span><span>uploadFile</span><span>(<span>$path</span>=<span>"upload/"</span>,<span>$allowExt</span>=array<span>(<span>"gif"</span>,<span>"jpeg"</span>,<span>"png"</span>,<span>"jpg"</span>,<span>"wbmp"</span>)</span>,<span>$imgFlag</span>=true)</span>

}</span></code>

多文件上傳分為兩種情況
(1)多個單文件上傳

<code><span><span>html</span>></span><span>head</span>><span>meta</span><span>charset</span>=<span>"utf-8"</span>><span>title</span>><span><span>title</span>></span><span><span>head</span>></span><span>body</span>><span><!--  表單中enctype="multipart/form-data"的意思，是設(shè)置表單的MIME編碼。默認(rèn)情況，這個編碼格式是application/x-www-form-urlencoded，不能用于文件上傳；只有使用了multipart/form-data，才能完整的傳遞文件數(shù)據(jù)，進(jìn)行下面的操作.
--></span><span>FORM</span><span>action</span>=<span>"doAction2.php"</span><span>method</span>=<span>"post"</span><span>enctype</span>=<span>"multipart/form-data"</span>><span>INPUT</span><span>type</span>=<span>"hidden"</span><span>name</span>=<span>"MAX_FILE_SIZE"</span><span>value</span>=<span>"1048576"</span>/>    請選擇上傳文件:<span>INPUT</span><span>type</span>=<span>"file"</span><span>name</span>=<span>"myFile1"</span>/><span>br</span>/>
  請選擇上傳文件:<span>INPUT</span><span>type</span>=<span>"file"</span><span>name</span>=<span>"myFile2"</span>/><span>br</span>/>
  請選擇上傳文件:<span>INPUT</span><span>type</span>=<span>"file"</span><span>name</span>=<span>"myFile3"</span>/><span>br</span>/><span>input</span><span>type</span>=<span>"submit"</span><span>value</span>=<span>"上傳"</span>/><span><span>FORM</span>></span><span><span>body</span>></span><span><span>html</span>></span></code>

這種形式相當(dāng)于上傳了多個單文件,在doAction2.php中print_r($_FILES);得到

<code><span>Array</span>
(
    [myFile1] => <span>Array</span>
        (
            [name] => touxiang.jpg
            [type] => image/jpeg
            [tmp_name] => D:\xampp\tmp\php79E3.tmp
            [error] => <span>0</span>
            [size] => <span>28747</span>
        )

    [myFile2] => <span>Array</span>
        (
            [name] => 文章.png
            [type] => image/png
            [tmp_name] => D:\xampp\tmp\php7A03.tmp
            [error] => <span>0</span>
            [size] => <span>11655</span>
        )

    [myFile3] => <span>Array</span>
        (
            [name] => 增加.png
            [type] => image/png
            [tmp_name] => D:\xampp\tmp\php7A04.tmp
            [error] => <span>0</span>
            [size] => <span>7439</span>
        )

)</code>

(2)多文件上傳

<code><span><span>html</span>></span><span>head</span>><span>meta</span><span>charset</span>=<span>"utf-8"</span>><span>title</span>><span><span>title</span>></span><span><span>head</span>></span><span>body</span>><span><!--  表單中enctype="multipart/form-data"的意思，是設(shè)置表單的MIME編碼。默認(rèn)情況，這個編碼格式是application/x-www-form-urlencoded，不能用于文件上傳；只有使用了multipart/form-data，才能完整的傳遞文件數(shù)據(jù)，進(jìn)行下面的操作.
--></span><span>FORM</span><span>action</span>=<span>"doAction2.php"</span><span>method</span>=<span>"post"</span><span>enctype</span>=<span>"multipart/form-data"</span>><span>INPUT</span><span>type</span>=<span>"hidden"</span><span>name</span>=<span>"MAX_FILE_SIZE"</span><span>value</span>=<span>"1048576"</span>/>  請選擇上傳文件:<span>INPUT</span><span>type</span>=<span>"file"</span><span>name</span>=<span>"myFile[]"</span>/><span>br</span>/>
  請選擇上傳文件:<span>INPUT</span><span>type</span>=<span>"file"</span><span>name</span>=<span>"myFile[]"</span>/><span>br</span>/>
  請選擇上傳文件:<span>INPUT</span><span>type</span>=<span>"file"</span><span>name</span>=<span>"myFile[]"</span>/><span>br</span>/><span>input</span><span>type</span>=<span>"submit"</span><span>value</span>=<span>"上傳"</span>/><span><span>FORM</span>></span><span><span>body</span>></span><span><span>html</span>></span></code>

同樣print_r($_files)一下

<code><span>Array</span>
(
    [myFile] => <span>Array</span>
        (
            [name] => <span>Array</span>
                (
                    [<span>0</span>] => touxiang.jpg
                    [<span>1</span>] => 文章.png
                    [<span>2</span>] => 增加.png
                )

            [type] => <span>Array</span>
                (
                    [<span>0</span>] => image/jpeg
                    [<span>1</span>] => image/png
                    [<span>2</span>] => image/png
                )

            [tmp_name] => <span>Array</span>
                (
                    [<span>0</span>] => D:\xampp\tmp\php1EC.tmp
                    [<span>1</span>] => D:\xampp\tmp\php1ED.tmp
                    [<span>2</span>] => D:\xampp\tmp\php1EE.tmp
                )

            [error] => <span>Array</span>
                (
                    [<span>0</span>] => <span>0</span>
                    [<span>1</span>] => <span>0</span>
                    [<span>2</span>] => <span>0</span>
                )

            [size] => <span>Array</span>
                (
                    [<span>0</span>] => <span>28747</span>
                    [<span>1</span>] => <span>11655</span>
                    [<span>2</span>] => <span>7439</span>
                )

        )

)
</code>

發(fā)現(xiàn)兩種方式得到的數(shù)組有很多的不同。
對于第一種的情況(相當(dāng)于一個文件數(shù)組)我們可以

<code><span>foreach</span> (<span>$_FILES</span><span>as</span><span>$var</span>)
{
    <span>//對于每一個文件進(jìn)行了文件上傳操作</span><span>$info</span>=uploadFile(<span>$var</span>);
    <span>echo</span><span>$info</span>;
}</code>

對于第二種情況我們可以將所示的三維數(shù)組轉(zhuǎn)換為第一種情況所示的二維數(shù)組即可。

<code>foreach(<span>$_FILES</span>[myFile][name] as <span>$key</span>=><span>$var</span> )
{
    <span>$files</span>[<span>$key</span>][name]=<span>$_FILES</span>[myFile][name][<span>$key</span>];
    <span>$files</span>[<span>$key</span>][type]=<span>$_FILES</span>[myFile][type][<span>$key</span>];
    <span>$files</span>[<span>$key</span>][tmp_name]=<span>$_FILES</span>[myFile][tmp_name][<span>$key</span>];
    <span>$files</span>[<span>$key</span>][<span>error</span>]=<span>$_FILES</span>[myFile][<span>error</span>][<span>$key</span>];
    <span>$files</span>[<span>$key</span>][<span>size</span>]=<span>$_FILES</span>[myFile][<span>size</span>][<span>$key</span>];
}
print_r(<span>$files</span>);</code>

結(jié)果

<code><span>Array</span>
(
    [<span>0</span>] => <span>Array</span>
        (
            [name] => touxiang.jpg
            [type] => image/jpeg
            [tmp_name] => D:\xampp\tmp\php3227.tmp
            [error] => <span>0</span>
            [size] => <span>28747</span>
        )

    [<span>1</span>] => <span>Array</span>
        (
            [name] => 文章.png
            [type] => image/png
            [tmp_name] => D:\xampp\tmp\php3228.tmp
            [error] => <span>0</span>
            [size] => <span>11655</span>
        )

    [<span>2</span>] => <span>Array</span>
        (
            [name] => 增加.png
            [type] => image/png
            [tmp_name] => D:\xampp\tmp\php3229.tmp
            [error] => <span>0</span>
            [size] => <span>7439</span>
        )

)</code>

成功了，現(xiàn)在我們開始封裝一個文件上傳函數(shù)，這個函數(shù)呢既可以處理單文件上傳又可以處理多文件上傳。然后我們只需要編寫數(shù)組處理的這部分，然后調(diào)用upload()函數(shù)即可。

<code><span><?php </span><span>require_once</span><span>"../include.php"</span>;
<span>//用于轉(zhuǎn)換數(shù)組</span><span><span>function</span><span>buildInfo</span><span>()</span>
{</span><span>foreach</span>(<span>$_FILES</span><span>as</span><span>$file</span>)
    {
        <span>$i</span>=<span>0</span>;
        <span>if</span>(is_string(<span>$file</span>[<span>'name'</span>]))
        {
            <span>$files</span>[<span>$i</span>]=<span>$file</span>;
            <span>$i</span>++;
        }
        <span>else</span>
        {
