How can syntax highlighting in editors help in identifying and fixing parse errors in PHP code?

Syntax highlighting in editors can help in identifying and fixing parse errors in PHP code by visually highlighting different parts of the code based on their syntax, such as keywords, variables, strings, and comments. This can make it easier to spot syntax errors, such as missing semicolons, parentheses, or quotation marks, which can cause parse errors in PHP code. By fixing these syntax errors highlighted by the editor, you can prevent parse errors and ensure that your PHP code runs correctly.

```php
<?php

// Incorrect code with syntax errors
$variable = "Hello World'
echo $variable;

?>
```

In the above code snippet, the syntax highlighting in the editor would likely highlight the syntax errors in the code, such as the missing closing quotation mark in the string assignment and the missing semicolon at the end of the `echo` statement. By correcting these syntax errors, the parse errors in the PHP code can be fixed.
