What steps can be taken to troubleshoot and resolve parse errors in PHP scripts effectively?

Parse errors in PHP scripts typically occur due to syntax errors, such as missing semicolons, parentheses, or curly braces. To troubleshoot and resolve parse errors effectively, carefully review the code for any syntax mistakes and use an IDE or text editor with syntax highlighting to pinpoint the error. Additionally, utilizing PHP's error reporting functions, such as error_reporting(E_ALL), can help identify the exact location of the parse error.

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

To fix the parse error in the code snippet above, add a semicolon at the end of the first line:

```php
<?php
// Corrected code snippet without parse error
$name = "John";
echo "Hello, $name!";
?>
