What are some best practices for debugging PHP scripts that are not executing as expected?

Issue: When PHP scripts are not executing as expected, it is important to utilize debugging techniques to identify and resolve the issue. Some best practices for debugging PHP scripts include checking for syntax errors, using print statements to output variable values, utilizing error reporting functions, and logging errors to a file for further analysis. PHP Code Snippet: 

<?php
// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Check for syntax errors
if (count($array) > 0) {
    foreach ($array as $item) {
        echo $item;
    }
} else {
    echo "Array is empty.";
}

// Output variable values
$var = "Hello, World!";
echo $var;

// Log errors to a file
$errorLog = fopen("error.log", "a");
fwrite($errorLog, "Error message here");
fclose($errorLog);
?>
