What are some common pitfalls or challenges when trying to open PHP files?

One common challenge when trying to open PHP files is encountering syntax errors, which can prevent the file from being executed properly. To solve this issue, carefully check the syntax of the PHP code for any mistakes such as missing semicolons, parentheses, or curly braces. 

<?php

// Example PHP code snippet with syntax error
echo "Hello, World"
?>
```

Another pitfall is not having the correct file permissions set, which can prevent the PHP file from being accessed or executed by the server. To fix this, ensure that the file has the appropriate permissions set to allow the server to read and execute it.

```php
<?php

// Example PHP code snippet to set file permissions
chmod("example.php", 0644);
