PHP獲取搜索引擎關(guān)鍵字來源的函數(shù)(支持百度和谷歌等搜索引擎)
Jun 13, 2016 am 11:57 AM
最近遇到一個(gè)項(xiàng)目，客戶需要一個(gè)功能，一個(gè)商品銷售下單需要知道用戶下單是從哪個(gè)途徑來的，認(rèn)為客服軟件（53客服）和站長(zhǎng)統(tǒng)計(jì)只能滿足工作時(shí)間，及晚上下班和周六日休息，客服不在線，用戶下單會(huì)不知道該訂單的具體來源，所以嘛，又只能通過網(wǎng)站功能來增加一字段，獲取來源關(guān)鍵字，如何獲取來源關(guān)鍵字，代碼發(fā)在下面，里面包含（百度、谷歌、雅虎、搜狗、搜搜、必應(yīng)、有道）幾大搜索引擎的獲取方法，代碼中均注明，希望對(duì)你有幫助，分享一下
代碼如下：

?>
有一點(diǎn)要記住，由于各搜索引擎的頁面編碼不一樣，有的是GBK,有的是UTF8,所以在獲取時(shí)會(huì)有不同對(duì)字符編碼的轉(zhuǎn)換
轉(zhuǎn)載請(qǐng)注明：http://www.netxu.com/program/12.html

A Simple Guide to PHP Setup
Jul 18, 2025 am 04:25 AM
The key to setting up PHP is to clarify the installation method, configure php.ini, connect to the web server and enable necessary extensions. 1. Install PHP: Use apt for Linux, Homebrew for Mac, and XAMPP recommended for Windows; 2. Configure php.ini: Adjust error reports, upload restrictions, etc. and restart the server; 3. Use web server: Apache uses mod_php, Nginx uses PHP-FPM; 4. Install commonly used extensions: such as mysqli, json, mbstring, etc. to support full functions.
Tips for Writing PHP Comments
Jul 18, 2025 am 04:51 AM
The key to writing PHP comments is to clarify the purpose and specifications. Comments should explain "why" rather than "what was done", avoiding redundancy or too simplicity. 1. Use a unified format, such as docblock (/*/) for class and method descriptions to improve readability and tool compatibility; 2. Emphasize the reasons behind the logic, such as why JS jumps need to be output manually; 3. Add an overview description before complex code, describe the process in steps, and help understand the overall idea; 4. Use TODO and FIXME rationally to mark to-do items and problems to facilitate subsequent tracking and collaboration. Good annotations can reduce communication costs and improve code maintenance efficiency.
Writing Effective PHP Comments
Jul 18, 2025 am 04:44 AM
Comments cannot be careless because they want to explain the reasons for the existence of the code rather than the functions, such as compatibility with old interfaces or third-party restrictions, otherwise people who read the code can only rely on guessing. The areas that must be commented include complex conditional judgments, special error handling logic, and temporary bypass restrictions. A more practical way to write comments is to select single-line comments or block comments based on the scene. Use document block comments to explain parameters and return values at the beginning of functions, classes, and files, and keep comments updated. For complex logic, you can add a line to the previous one to summarize the overall intention. At the same time, do not use comments to seal code, but use version control tools.
Improving Readability with Comments
Jul 18, 2025 am 04:46 AM
The key to writing good comments is to explain "why" rather than just "what was done" to improve the readability of the code. 1. Comments should explain logical reasons, such as considerations behind value selection or processing; 2. Use paragraph annotations for complex logic to summarize the overall idea of functions or algorithms; 3. Regularly maintain comments to ensure consistency with the code, avoid misleading, and delete outdated content if necessary; 4. Synchronously check comments when reviewing the code, and record public logic through documents to reduce the burden of code comments.

Effective PHP Commenting
Jul 18, 2025 am 04:33 AM
The key to writing PHP comments is clear, useful and concise. 1. Comments should explain the intention behind the code rather than just describing the code itself, such as explaining the logical purpose of complex conditional judgments; 2. Add comments to key scenarios such as magic values, old code compatibility, API interfaces, etc. to improve readability; 3. Avoid duplicate code content, keep it concise and specific, and use standard formats such as PHPDoc; 4. Comments should be updated synchronously with the code to ensure accuracy. Good comments should be thought from the perspective of others, reduce the cost of understanding, and become a code understanding navigation device.
