How can PHP beginners effectively troubleshoot and resolve issues with their code?

Issue: One common issue for PHP beginners is syntax errors, such as missing semicolons or parentheses, which can cause their code to not run properly. Solution: To troubleshoot syntax errors, beginners should carefully review their code for any missing or misplaced punctuation marks and use an IDE or code editor that highlights syntax errors. Additionally, beginners can use tools like PHP's built-in error reporting functions to pinpoint the exact location of the syntax error.

```php
<?php

// Example code with missing semicolon
$name = "John"
echo "Hello, $name!";

?>
```

In this example, the missing semicolon after the variable declaration of `$name` will cause a syntax error. By adding the semicolon at the end of the line, the code will run without any issues.
