How can PHP syntax highlighting help in identifying errors in code?

PHP syntax highlighting can help in identifying errors in code by visually distinguishing different elements of the code, such as variables, functions, and keywords. This makes it easier to spot syntax errors, missing semicolons, and other common mistakes that can cause code to break. By using a code editor with syntax highlighting, developers can quickly identify and correct errors, leading to more efficient debugging and troubleshooting.

```php
<?php
// Incorrect code with missing semicolon
$name = "John"
echo "Hello, $name!";
?>
```

By using a code editor with syntax highlighting, the missing semicolon in the code snippet above would be visually highlighted, making it easier to spot and correct.
