// Open a file for writing $file = fopen("example.txt", "w") or die("Unable to open file!"); // Write data to the file $txt = "This is some text."; fwrite($file, $txt); // Close the file fclose($file);
// Create a new file and write data to it $file = 'newfile.txt'; $data = 'This is new data.'; if (file_put_contents($file, $data) !== false) { echo "File created successfully."; } else { echo "Error creating file!"; }In this example, the file_put_contents() function is used to create a new file with data. If the function is successful, it returns the number of bytes written to the file. Otherwise, it returns false. In terms of determining the package library for PHP Filesystem write functionality, it is typically part of the core PHP language and does not require any external library or package.
