本文介绍如何使用curl_setopt_array函数批量设置cURL会话的多个选项，提高代码效率。通过示例展示了初始化cURL会话并获取网页的过程，并提供了一个自定义实现curl_setopt_array的方法。

总的来说就是给curl session $ch 按数组格式设置它的option 下面的详细的.

(PHP 5 >= 5.1.3 )

curl_setopt_array — Set multiple options for a cURL transfer

说明

bool curl_setopt_array ( resource $ch , array $options )

Sets multiple options for a cURL session. This function is useful for setting a large amount of cURL options without repetitively calling curl_setopt() .

参数

A cURL handle returned by curl_init() .

options

An array specifying which options to set and their values. The keys should be valid curl_setopt() constants or their integer equivalents.

返回值

Returns TRUE if all options were successfully set. If an option could not be successfully set, FALSE is immediately returned, ignoring any future options in the options array.

范例

范例#1 Initializing a new cURL session and fetching a web page

 <?php
  // create a new cURL resource
  $ch  =  curl_init ();
 
  // set URL and other appropriate options
  $options  = array( CURLOPT_URL  =>  'http://www.example.com/' ,
                   CURLOPT_HEADER  =>  false
                  );
 
  curl_setopt_array ( $ch ,  $options );
 
  // grab URL and pass it to the browser
  curl_exec ( $ch );
 
  // close cURL resource, and free up system resources
  curl_close ( $ch );
  ?>

Prior to PHP 5.1.4 this function can be simulated with(5 .1.4之前的版本，我们可以如下模仿这个函数 ):

范例#2 Our own implementation of curl_setopt_array()

 <?php
  if (! function_exists ( 'curl_setopt_array' )) {
    function  curl_setopt_array (& $ch ,  $curl_options )
    {
        foreach ( $curl_options  as  $option  =>  $value ) {
            if (! curl_setopt ( $ch ,  $option ,  $value )) {
                return  false ;
            } 
        }
        return  true ;
    }
 }
  ?>
