File handling Basics
PHP supports this feature using the following functions:
- fopen: To open a file in a particular mode, like r: read, w: write, a: append etc.
- feof: To check whether the pointer has reached at the end of the file or not.
- fclose: To close the file.
- fgets: To extract the content line by line.
- fgetc: To extract the content character by character.
