Php can establish a connection only once to obtain remote content and use it multiple times. Solution-php Tutorial

Php can establish a connection only once to obtain remote content and use it multiple times. example: & nbsp; $ chcurl_init (); & nbsp; $ timeout30; & nbsp; curl_setopt ($ ch, CURLOPT_URL, $ url); & nbsp; curl_setopt ($ ch, CU php can obtain remote content, establish a connection only once, and use it multiple times.
For example:
$ Ch = curl_init ();
$ Timeout = 30;
Curl_setopt ($ ch, CURLOPT_URL, $ url );
Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1 );
Curl_setopt ($ ch, CURLOPT_CONNECTTIMEOUT, $ timeout );
Curl_setopt ($ ch, CURLOPT_FOLLOWLOCATION, 1 );
$ Contents = trim (curl_exec ($ ch ));
Curl_close ($ ch );

The url of the target address is stable and only the parameters passed are different,
Can the code contain only
$ Timeout = 30;
Curl_setopt ($ ch, CURLOPT_URL, $ url );
Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1 );
Curl_setopt ($ ch, CURLOPT_CONNECTTIMEOUT, $ timeout );
Curl_setopt ($ ch, CURLOPT_FOLLOWLOCATION, 1 );
$ Contents = trim (curl_exec ($ ch ));
You do not need to create a connection or close a connection each time.
