How can regex be effectively used to extract specific variables from a PHP file for use in a different script?

To extract specific variables from a PHP file using regex for use in a different script, you can use regular expressions to search for and capture the desired variables. This can be done by defining patterns that match the variable names and their corresponding values in the PHP file. Once the variables are extracted, you can then use them in your desired script. 

<?php
// Read the contents of the PHP file
$phpFileContent = file_get_contents('example.php');

// Define the regex pattern to match the variables
$pattern = '/\$variableName\s*=\s*(.*?);/';

// Match the pattern in the PHP file content
preg_match($pattern, $phpFileContent, $matches);

// Extract the variable value
$variableValue = $matches[1];

// Use the extracted variable in your script
echo $variableValue;
?>
