    ▪解析PHP 使用curl提交json格式数据       代码如下:$data = array("name" => "Hagrid", "age" => "36");$data_string = json_encode($data); $ch = curl_init('http://api.local/rest/users');curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");curl_setopt($ch, CURLOPT_POSTFIELDS,$data_string);.........

    ▪PHP 过滤页面中的BOM(实现代码)       代码如下:function checkBOM ($filename) {       $contents = file_get_contents($filename);       $charset[1] = substr($contents, 0, 1);       $charset[2] = substr($contents, 1, 1);      $charset[3] = substr($contents, 2, 1);.........

    ▪解析curl提交GET,POST,Cookie的简单方法       代码如下:<?php$get_data = array (    "get1"=> "get1",    "get2" => "get2",    "get3" => "get3");$curl = curl_init();curl_setopt($curl, CURLOPT_URL, 'http://test.test.com/test.php?'.http_build_query($get_data));curl_setopt($c.........

代码如下:

$data = array("name" => "Hagrid", "age" => "36");
$data_string = json_encode($data);

$ch = curl_init('http://api.local/rest/users');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Content-Length: ' . strlen($data_string))
);

$result = curl_exec($ch);

代码如下:

function checkBOM ($filename) {
       $contents = file_get_contents($filename);
       $charset[1] = substr($contents, 0, 1);
       $charset[2] = substr($contents, 1, 1);
      $charset[3] = substr($contents, 2, 1);
      if (ord($charset[1]) == 239 && ord($charset[2]) == 187 && ord($charset[3]) == 191) {
               $rest = substr($contents, 3);
               rewrite $rest;
      }else{
　　　　　　return false;
　　　 }
 }

代码如下:

<?php
$get_data = array (
    "get1"=> "get1",
    "get2" => "get2",
    "get3" => "get3"
);
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, 'http://test.test.com/test.php?'.http_build_query($get_data));
curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.97 Safari/537.11');
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
$post_data = array (
    "p1" => "test1",
    "p2" => "test2",
    "p3" => "test3"
);
curl_setopt($curl, CURLOPT_POST, true);
//["CONTENT_TYPE"]=> string(70) "multipart/form-data; boundary=------077a996f5afe"
//要发送文件，在文件名前面加上@前缀并使用完整路径。
//使用数组提供post数据时，CURL组件大概是为了兼容@filename这种上传文件的写法，默认把content_type设为了multipart/form-data。
//虽然对于大多数web服务器并没有影响，但是还是有少部分服务器不兼容。
curl_setopt($curl, CURLOPT_POSTFIELDS, $post_data);
//["CONTENT_TYPE"]=> string(33) "application/x-www-form-urlencoded"
//curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($post_data));
//在没有需要上传文件的情况下，尽量对post提交的数据进行http_build_query，然后发送出去，能实现更好的兼容性，更小的请求数据包。
$cookies = array(

$cookies_string = '';
foreach($cookies as $name=>$value){
