Encapsulation of CURL in yii11

: This article mainly introduces CURL encapsulation in yii11. For more information about PHP tutorials, see. The flexible extension of the Yii Framework is favored by companies. Therefore, yii is used in the project. to be compatible with the original system, yii1.1 is still selected.

Here we will not talk about the features of yii, but mainly about the re-encapsulation of curl when yii is used.

Let's take a look at the yii configuration file and configure curl as Components in main. php.

'Components' => array (// Curl library call: Yii: app ()-> curl 'curl' => array ('class' => 'ext. curl. curl ', 'options' => array (CURLOPT_HTTPHEADER => array ('expect CT:'), CURLOPT_HEADER => '',),),

 True, CURLOPT_FOLLOWLOCATION => true, CURLOPT_HEADER => false, CURLOPT_VERBOSE => true, CURLOPT_AUTOREFERER => true, CURLOPT_CONNECTTIMEOUT => 30, CURLOPT_TIMEOUT => 30, limit => false, CURLOPT_USERAGENT => 'mozilla/5.0 (compatible; Googlebot/2.1; + http://www.google.com/bot.html ) '); Private function exec ($ url) {$ this-> setOption (CURLOPT_URL, $ url); $ this-> response = curl_exec ($ this-> _ ch ); if (!

The above introduces the CURL re-encapsulation in yii11, including some content, and hope to be helpful to friends who are interested in PHP tutorials.
