PHP Feature 01: cURL implements get and post, and performs data interaction between URLs;

One background

The development interface of WeChat public account usually uses http request, selects http/https protocol, supports curl command to get or post data;

two php function cURL function

01 Initialize cURL Session, return handle;
resource curl_init ([ string $url = NULL ] )
02 Set a cURL transfer option;
bool curl_setopt ( resource $ch , int $option , mixed $value )
ex: curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); <br> //Return the information obtained by curl_exec() in the form of a file stream instead of outputting it directly.
03 Execute cURL session
mixed curl_exec ( resource $ch )mixed curl_exec ( resource $ch )

04 Close a cURL session and release all resources. The cURL handle ch will also be released void curl_close ( resource $ch )

void curl_close ( resource $ch )

🎜Three PHP Get and Post implementation🎜

Get // Scenario 1: Upload picture materials to WeChat server
`ch=curli nit( );access_token; //Interface call credentials; need to be obtained actively;
typ e=“ image";url = "http://file.api.weixin.qq.com/cgi-bin/media/ upload?access_token=access_token&type=type”;
$filepath = dirname(FILE)."test.jpg";
filedata =a rray("media"= >" @".filepath);
curl_setopt(ch,CURLOP TU RL,url); // Required
curl_setopt(ch,CURLOP TR ETURNTRANSFER ,1) " curl setopt(ch, CURLOPT_POST,1); // post data curl_setopt(ch,CURLOP T
P // post variable curl_setopt(ch,CURLOP TH EADER,0);
output = curl_exec( ch) ;curl_close(ch);va rd ump(output); // Decompress json data packet; outputa rray= jsondecode (output,true ); d
=output_array[" media_id”]; echo $media_id; "Post // Download picture material (part CODE) from WeChat server access t
