How to get the return value in php curl

Contents of this section: How to implement php curl to get the return value

There is a parameter curlopt_returntransfer in curl:

curl_setopt($ch, curlopt_returntransfer, 0);

The default is 0 to directly return the text stream of the obtained output. Sometimes the return value is used for judgment or other purposes. Fortunately curlopt_returntransfer can be set, if set to curlopt_returntransfer 1:

curl_setopt($ch, curlopt_returntransfer, 1);

can be used without curl_close before closing a curl session: curl_multi_getcontent($ch) You can get the server return value. It is a string type! The php manual is as follows:

curl_multi_getcontent( resource $ch )

If curlopt_returntransfer as an option is set to a specific handle, then this function will return the content obtained by that curl handle in the form of a string .
