Are there any best practices or considerations to keep in mind when using touch() to modify files in PHP?

When using the touch() function in PHP to modify files, it is important to consider the file permissions and error handling. Ensure that the file you are trying to modify has the appropriate permissions set to allow the operation. Additionally, always check for errors returned by the touch() function to handle any potential issues that may arise during the file modification process. 

$filename = 'example.txt';

if (touch($filename)) {
    echo "File modification successful";
} else {
    echo "Error modifying file";
}
