What are the best practices for passing variables from PHP to a Perl script using cURL?

When passing variables from PHP to a Perl script using cURL, it is important to properly encode the data to prevent any issues with special characters. One common method is to use the `http_build_query` function in PHP to encode the variables as a query string. This ensures that the data is formatted correctly before sending it to the Perl script via cURL. 

<?php
// Variables to pass to Perl script
$var1 = 'value1';
$var2 = 'value2';

// Encode variables as a query string
$data = http_build_query(array(
    'var1' => $var1,
    'var2' => $var2
));

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

// Set cURL options
curl_setopt($ch, CURLOPT_URL, 'http://example.com/script.pl');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

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

// Close cURL session
curl_close($ch);

// Handle response from Perl script
echo $response;
?>
