What are common issues with file permissions in PHP scripts?

Common issues with file permissions in PHP scripts include not having the necessary permissions to read, write, or execute a file. This can lead to errors or unexpected behavior in your script. To solve this issue, you can use the `chmod()` function in PHP to change the file permissions to allow the necessary access. 

// Set file permissions to allow read and write access
$file = 'example.txt';
$permissions = 0644; // Read and write for owner, read for others
chmod($file, $permissions);
