What common syntax errors can lead to a "Parse error" in PHP code, as seen in the provided script?

A common syntax error that can lead to a "Parse error" in PHP code is missing or mismatched parentheses, brackets, or curly braces. This error occurs when the opening and closing characters do not match properly, causing the parser to fail in understanding the code structure. To solve this issue, carefully check the code for any missing or incorrectly placed parentheses, brackets, or curly braces and ensure they are properly balanced. Example of a PHP code snippet with corrected syntax:

<?php

// Incorrect code with a missing closing parenthesis
if ($x > 5 {
    echo "x is greater than 5";
}

// Corrected code with the closing parenthesis added
if ($x > 5) {
    echo "x is greater than 5";
}

?>
