PHP, CURL. What does curl_exec return?

Question

I\'m trying to set an API with a payment processor. Below is the code they provided me. There are some information in the $result variable that I want, what I don\'t underst

Answer 1

From the manual:

Returns TRUE on success or FALSE on failure. However, if the CURLOPT_RETURNTRANSFER option is set, it will return the result on success, FALSE on failure.

Your code already contains this line (which is good):

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

The 1 means you will receive an explanatory result back from $result = curl_exec ($ch) instead of just true or false.

Your error checking code could therefore look like:

$result = curl_exec ($ch);
if($result === FALSE) {
    die(curl_error($ch));
}

You can also check they type of variable returned via var_dump: var_dump($result).
