【PHP】PHP实现网络请求的方法及函数总结 一、分析php发送网网络请求的方法对于php发送网络请求，我们最常用的请求就是curl,有时我们也会用到file_get_contents函数发送网络请求，但file_get_contents只能完成一些间单的网络请求，稍复杂的就无法完成，例如文件上传，cookies，验证，表单提交等，用php的curl可以使用URL的语法模拟浏览器来传输数据，因为它是模拟浏览器，因此它同样支持多种协议，FTP, FTPS, HTTP, HTTPS, GOPHER, TELNET, DICT, FILE 以及 LDAP等协议都可以很好的支持，包括一些：HTTPS认证，HTTP POST方法，HTTP PUT方法，FTP上传，keyberos认证，HTTP上传，代理服务器，cookies，用户名/密码认证，下载文件断点续传，上传文件断点续传，http代理服务器管道，甚至它还支持IPv6，scoket5代理服务器，通过http代理服务器上传文件到FTP服务器等等，所以我们在开发中尽量用curl发网络请求，无论是简单还是复杂二、file_get_contents发送网络请求示例file_get_contents(path,include_path,context,start,max_length)一般用file_get_contents或者fopen, file , readfile等函数读取url的时候 会创建一个$http_response_header变量保存HTTP响应的报头,使用fopen等函数打开的数据流信息可以用stream_get_meta_data获取$html = file_get_contents('http://www.baidu.com'); print_r($http_response_header); $fp = fopen('http://www.baidu.com', 'r'); print_r(stream_get_meta_data($fp)); fclose($fp);摸拟post请求：$url = 'http://192.168.1.1/test.php'; $data = array( 'keyword' => 'test data', ); $content = http_build_query($data); $content_length = strlen($content); $options = array( 'http' => array( 'method' => 'POST', 'header' => "Content-type: application/x-www-form-urlencoded\r\n" . "Content-length: $content_length\r\n", 'content' => $content ) ); echo file_get_contents($url, false, stream_context_create($options));三、php 用curl发送网络请求curl可以支持https认证、http post、ftp上传、代理、cookies、简单口令认证等等功能,使用前需要先在你的PHP环境中安装和启用curl模块，这里有两种写法供大家参考：<?php function geturl($url){ $headerArray =array("Content-type:application/json;","Accept:application/json"); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch,CURLOPT_HTTPHEADER,$headerArray); $output = curl_exec($ch); curl_close($ch); $output = json_decode($output,true); return $output; } function posturl($url,$data){ $data = json_encode($data); $headerArray =array("Content-type:application/json;charset='utf-8'","Accept:application/json"); $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST,FALSE); curl_setopt($curl, CURLOPT_POST, 1); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); curl_setopt($curl,CURLOPT_HTTPHEADER,$headerArray); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); $output = curl_exec($curl); curl_close($curl); return json_decode($output，true); } function puturl($url,$data){ $data = json_encode($data); $ch = curl_init(); //初始化CURL句柄 curl_setopt($ch, CURLOPT_URL, $url); //设置请求的URL curl_setopt ($ch, CURLOPT_HTTPHEADER, array('Content-type:application/json')); curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); //设为TRUE把curl_exec()结果转化为字串，而不是直接输出 curl_setopt($ch, CURLOPT_CUSTOMREQUEST,"PUT"); //设置请求方式 curl_setopt($ch, CURLOPT_POSTFIELDS, $data);//设置提交的字符串 $output = curl_exec($ch); curl_close($ch); return json_decode($output,true); } function delurl($url,$data){ $data = json_encode($data); $ch = curl_init(); curl_setopt ($ch,CURLOPT_URL,$put_url); curl_setopt ($ch, CURLOPT_HTTPHEADER, array('Content-type:application/json')); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_CUSTOMREQUEST, "DELETE"); curl_setopt($ch, CURLOPT_POSTFIELDS,$data); $output = curl_exec($ch); curl_close($ch); $output = json_decode($output,true); } function patchurl($url,$data){ $data = json_encode($data); $ch = curl_init(); curl_setopt ($ch,CURLOPT_URL,$url); curl_setopt ($ch, CURLOPT_HTTPHEADER, array('Content-type:application/json')); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_CUSTOMREQUEST, "PATCH"); curl_setopt($ch, CURLOPT_POSTFIELDS,$data); //20170611修改接口，用/id的方式传递，直接写在url中了 $output = curl_exec($ch); curl_close($ch); $output = json_decode($output); return $output; } ?>一个函数片时各种请求：function sendCurl($url, $data = null,$method='POST') { $method=strtoupper($method); $start_wdmcurl_time = microtime(true); $header = array(' application/x-www-form-urlencoded'); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_FAILONERROR, false); // https 请求 if (strlen($url) > 5 && strtolower(substr($url, 0, 5)) == "https") { curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); } if($method=='GET'){ if($data && is_array($data) && count($data)>0 ){ $url.="?".http_build_query($data); } curl_setopt($ch, CURLOPT_URL, $url); }elseif($method=='POST'){ curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); if (is_array($data) && count($data)>0) { curl_setopt($ch, CURLOPT_POST, true); $isPostMultipart = false; foreach ($data as $k => $v) { if ('@' == substr($v, 0, 1)) { $isPostMultipart = true; break; } } unset($k, $v); if ($isPostMultipart) { curl_setopt($ch, CURLOPT_POSTFIELDS, $data); } else { curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data)); } } }elseif(in_array($method,['PUT','DELETE','PATCH'])){ curl_setopt($ch, CURLOPT_CUSTOMREQUEST,$method); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); } curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch,CURLOPT_HTTPHEADER,$header); $reponse = curl_exec($ch); curl_close($ch); return $reponse; }四、使用php composer的扩展guzzlehttpcomposer require guzzlehttp/guzzle $client = new \GuzzleHttp\Client(); $response = $client->request('GET', 'https://api.github.com/repos/guzzle/guzzle'); echo $response->getStatusCode(); // 200 echo $response->getHeaderLine('content-type'); // 'application/json; charset=utf8' echo $response->getBody(); // '{"id": 1420053, "name": "guzzle", ...}' // Send an asynchronous request. $request = new \GuzzleHttp\Psr7\Request('GET', 'http://httpbin.org'); $promise = $client->sendAsync($request)->then(function ($response) { echo 'I completed! ' . $response->getBody(); }); $promise->wait();日常开发中我们尽量用方法三，自定义用curl处理网络请求，或用composer的guzzlehttp扩展库，有起来也很方便。学习地址：https://mp.weixin.qq.com/s/MOQyelYTv_UYYx9dqIOVRw

【PHP】PHP快速读取大文件指定行的方法 1、面临问题分析读取普通小文件我们一般用fopen 或者 file_get_contents就很方便简单 ,前者可以循环读取，后者可以一次性读取，但都是将文件内容一次性加载来操作。如果加载的文件特别大时，如几百M、上G时，这时性能贫瘠就非常突出了，那么PHP里有没有对大文件的处理函数或者类呢？ 答案是：有的。2、SplFileObject类高效解决大文件读取问题从 PHP 5.1.0 开始，SPL 库增加了 SplFileObject 与 SplFileInfo 两个标准的文件操作类。从字面意思理解看，可以看出 SplFileObject 要比 SplFileInfo 更为强大。不错，SplFileInfo 仅用于获取文件的一些属性信息，如文件大小、文件访问时间、文件修改时间、后缀名等值，而 SplFileObject 是继承 SplFileInfo 这些功能并新增很多文件处理类操作方法的一个文件操作类。 /** 返回文件从X行到Y行的内容(支持php5、php4) * @param string $filename 文件名 * @param int $startLine 开始的行数 * @param int $endLine 结束的行数 * @return string */ function getFileLines($filename, $startLine = 1, $endLine=50, $method='rb') { $content = array(); $count = $endLine - $startLine; // 判断php版本（因为要用到SplFileObject，PHP>=5.1.0） if(version_compare(PHP_VERSION, '5.1.0', '>=')){ $fp = new SplFileObject($filename, $method); $fp->seek($startLine-1);// 转到第N行, seek方法参数从0开始计数 for($i = 0; $i <= $count; ++$i) { $content[]=$fp->current();// current()获取当前行内容 $fp->next();// 下一行 } }else{//PHP<5.1 $fp = fopen($filename, $method); if(!$fp) return 'error:can not read file'; for ($i=1;$i<$startLine;++$i) {// 跳过前$startLine行 fgets($fp); } for($i;$i<=$endLine;++$i){ $content[]=fgets($fp);// 读取文件行内容 } fclose($fp); } return array_filter($content); // array_filter过滤：false,null,'' }Ps:（1）、上面都没加”读取到末尾的判断”：!$fp->eof() 或者 !feof($fp)，结果实践加上这个判断影响效率，而且这里加上也完全没必要。（2）、从上面的函数和实践操作就可以看出来使用SplFileObject类比下面的fgets函数效率要高很多，特别是文件行数非常多、并且要取越后面的内容的时候。fgets要两个循环才可以。

【PHP】PHP读取文件指定行的内容 function getLine($file, $line, $length = 40960){ $returnTxt = null; // 初始化返回 $i = 1; // 行数 $handle = @fopen($file, "r"); if ($handle) { while (!feof($handle)) { $buffer = fgets($handle, $length); if($line == $i) $returnTxt = $buffer; $i++; } fclose($handle); } return $returnTxt; }
