How can PHP developers effectively troubleshoot and debug syntax errors in their scripts?

To effectively troubleshoot and debug syntax errors in PHP scripts, developers can use tools like error reporting, syntax highlighting, and IDEs with built-in debugging capabilities. Additionally, carefully reviewing the code for typos, missing semicolons, parentheses, or curly braces can help identify and resolve syntax errors.

```php
<?php
// Example code snippet with a syntax error
$name = "John"
echo "Hello, $name!";
?>
```

In this code snippet, the syntax error is a missing semicolon after the variable assignment. Adding a semicolon at the end of the `$name` assignment statement will resolve the syntax error.
