How can syntax highlighting tools help identify errors in PHP scripts before execution?

Syntax highlighting tools can help identify errors in PHP scripts before execution by highlighting syntax errors, such as missing semicolons, parentheses, or quotation marks, in different colors. This visual indication can help developers quickly spot and correct mistakes in their code, preventing runtime errors. 

```php
<?php

// Incorrect code with syntax error
$name = "John"
echo "Hello, $name!";

?>
```

By using a syntax highlighting tool, the missing semicolon in the code snippet above would be highlighted, making it easier to identify and fix before running the script.
