I currently develop PHP based websites on a Mac using MAMP. When testing the Interspire Email Marketer API on a local version of a site posting data through to an https:// URL with cURL, I discovered that the version of cURL on MAMP has some issues with certs and SSL.
Original code
My original code posted some XML through to an https URL like so:
$ch = curl_init('https://www.example.com/example-api.php');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
$result = @curl_exec($ch);
The post was failing and all that was being returned into $result was false. Running this line of code after the above:
echo '<pre>', curl_error($ch);
produced this error message:
SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
My solution
I found a forum on the MAMP website which had a whole bunch of instructions about getting updated certificate files and so on, but the simplest solution was to simply not check the cert. I don’t need to have it checked because it’s a site I trust (being one of my own partner sites).
To disable the SSL checking add this line:
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
The revised piece of code in its entirety now looks like this:
$ch = curl_init(IEM_APIURL); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $xml); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); $result = @curl_exec($ch);
