When writing to a file, use the fwrite() function.
The first parameter of fwrite() is the file to write to; the second parameter is the string to be written.
The example below writes a couple of names into a new file called “names.txt”.
<?php $myfile = fopen("names.txt", "w"); $txt = "John\n"; fwrite($myfile, $txt); $txt = "David\n"; fwrite($myfile, $txt); fclose($myfile); /* File contains: John David */ ?>
Notice that we wrote to the file “names.txt” twice, and then we used the fclose() function to close the file.
The \n symbol is used when writing new lines.
