PHP feof( ) Function Last Updated : 26 Jun, 2023 Comments Improve Suggest changes Like Article Like Report The feof() function in PHP is an inbuilt function which is used to test for the end-of-file on a file pointer. It checks if the "end-of-file" has been reached or not. The feof() function is used for looping through the content of a file if the size of content is not known beforehand. The feof() function returns True if end-of-file has been reached or if an error has occurred. Else it returns False. Syntax: feof( $file ) Parameters: The feof() function in PHP accepts only one parameter which is $file. This parameter specifies the file which has to be checked for end-of-file. Return Value: It returns TRUE if end-of-file has been reached or if an error has occurred. Else it returns False. Errors And Exception: It goes in an infinite loop if the passed file pointer is not valid, because end-of-file fails to return True. feof() function hangs if a connection opened by fsockopen() isn't closed by the server.

Program 2: In the below program the file named "gfg.txt" contains the following text. This is the first line. This is the second line. This is the third line. php <?php // a file is opened using fopen() function $check = fopen("gfg.txt", "r"); $seq = fgets($check); // Outputs a line of the file until // the end-of-file is reached while(! feof($check)) { echo $seq ; $seq = fgets($check); } // file is closed using fclose() function fclose($check); ?> Output: This is the first line.
