What are common issues when trying to set permissions to 0777 in PHP?

Setting permissions to 0777 in PHP may not work due to restrictions set by the server's configuration or security policies. To solve this issue, you can try setting the permissions to a less permissive value, such as 0755, which still allows read, write, and execute permissions for the owner, but restricts write and execute permissions for others. 

// Set permissions to 0755 instead of 0777
$filename = 'example.txt';
chmod($filename, 0755);
