HomeBackend DevelopmentPHP Tutorial解析PHP中的file_get_contents获取远程页面乱码的问题_PHP

PHP的file_get_contents获取远程页面内容,如果是gzip编码过的,返回的字符串就是编码后的乱码
1、解决方法,找个ungzip的函数来转换下
2、给你的url加个前缀,这样调用
$content = file_get_contents("compress.zlib://".$url);
无论页面是否经过gzip压缩,上述代码都可以正常工作!
使用curl模块同样可解决问题
复制代码 代码如下:
function curl_get($url, $gzip=false){
        $curl = curl_init($url);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 10);
        if($gzip) curl_setopt($curl, CURLOPT_ENCODING, "gzip"); // 关键在这里
        $content = curl_exec($curl);
        curl_close($curl);
        return $content;
}

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
