In what ways can utilizing a code highlighter tool help identify errors in PHP code?

Utilizing a code highlighter tool can help identify errors in PHP code by providing syntax highlighting that makes it easier to spot mistakes such as missing semicolons, quotation marks, or incorrect function names. It can also help with indentations and formatting issues that may be causing errors in the code.

<?php

// Incorrect code with missing semicolon
echo "Hello, world"
echo "This is a test";

?>
