PHP5 curl_setopt_array 函数详解 PHP

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

ch: 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

  // 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()

  if (! function_exists ( 'curl_setopt_array' )) {
functioncurl_setopt_array (& $ch ,$curl_options )
{
foreach ( $curl_optionsas$option=>$value ) {
if (! curl_setopt ( $ch ,$option ,$value )) {
returnfalse ;

} 
}
returntrue ;

}
 }
 ?>
