PHP File Create/Write

This lesson is part of PHP · All levels

Summary

PHP can create new files and write data into them, for example to store log or export results. This lesson discusses fwrite(), file_put_contents(), and the differences between w (time) and a (plus) modes. It should be noted that w mode will delete all the old contents of the file.

Key points

Write the text to the file in one step
Write a string to the file that's already opened
W mode overlaps the old content, a mode adds to the end of the file
Check the writing results and handle the failures properly
