PHP Append File

PHP supports various modes of opening a file. The fopen() function is used to open a file in PHP. In general, fopen() function accepts two parameters:

Filename: This parameter specifies the name of the file to be opened.

Mode: This parameter specifies the mode in which the file should be opened.

resource fopen ( string $filename , string $mode )

The “a” or “a+” modes of fopen() function is used to append data into a file. The “a” mode opens a file in write only mode. While “a+” mode opens a file in read write mode. Both the modes continues writing in the existing file or creates a new file if it doesn’t exist. In both case, the pointer starts from the end of the file.
