Reading .DOC Files in PHP
Reading .DOC files in PHP can be challenging due to their binary format. However, you can parse them using the code provided by someone, but it may result in incorrect character interpretation.
To resolve this issue, you need to make the following modification:
<code class="php">$line = @fread($fileHandle, filesize($userDoc)); $lines = explode(chr(0x0A),$line);</code>
This change replaces the character chr(0x0D) with chr(0x0A). Windows stores newlines as rn (carriage return plus line feed), while UNIX systems use n (line feed only). By using chr(0x0D), you're treating the DOS/Windows newline character, but the file is stored in Unix format.
Additionally, consider the following code to read .docx files in PHP:
<code class="php">function read_file_docx($filename){
$striped_content = '';
$content = '';
if(!$filename || !file_exists($filename)) return false;
$zip = zip_open($filename);
if (!$zip || is_numeric($zip)) return false;
while ($zip_entry = zip_read($zip)) {
if (zip_entry_open($zip, $zip_entry) == FALSE) continue;
if (zip_entry_name($zip_entry) != "word/document.xml") continue;
$content .= zip_entry_read($zip_entry, zip_entry_filesize($zip_entry));
zip_entry_close($zip_entry);
}// end while
zip_close($zip);
$content = str_replace('</w:r></w:p></w:tc><w:tc>', " ", $content);
$content = str_replace('</w:r></w:p>', "\r\n", $content);
$striped_content = strip_tags($content);
return $striped_content;
}</code>
This code:
- Opens the .docx file as a ZIP archive.
- Extracts the "word/document.xml" file.
- Parses the XML content.
- Removes unnecessary tags and characters.
- Returns the parsed text content.

How do I destroy a session in PHP using session_destroy()?
Jun 20, 2025 am 01:06 AM
To completely destroy a session in PHP, you must first call session_start() to start the session, and then call session_destroy() to delete all session data. 1. First use session_start() to ensure that the session has started; 2. Then call session_destroy() to clear the session data; 3. Optional but recommended: manually unset$_SESSION array to clear global variables; 4. At the same time, delete session cookies to prevent the user from retaining the session state; 5. Finally, pay attention to redirecting the user after destruction, and avoid reusing the session variables immediately, otherwise the session needs to be restarted. Doing this will ensure that the user completely exits the system without leaving any residual information.
