What are the common issues faced when trying to pass POST data from PHP to a Perl script using cURL?

One common issue faced when passing POST data from PHP to a Perl script using cURL is ensuring that the data is formatted correctly in the request. This includes setting the appropriate Content-Type header and encoding the data properly. Additionally, it's important to properly handle any special characters or escaping needed for the data being passed. 

// Set the POST data to be sent in the cURL request
$postData = array(
    'key1' => 'value1',
    'key2' => 'value2'
);

// Initialize cURL session
$ch = curl_init();

// Set cURL options
curl_setopt($ch, CURLOPT_URL, 'http://example.com/perl_script.pl');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postData));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute cURL session
$response = curl_exec($ch);

// Close cURL session
curl_close($ch);

// Handle response from Perl script
echo $response;
