How to read a large file line by line?

Question

I want to read a file line by line, but without completely loading it in memory.

My file is too large to open in memory, and if try to do so I always get out of memory errors.

The file size is 1 GB.

You can use the fgets() function to read the file line by line:

$handle = fopen("inputfile.txt", "r"); if ($handle) {     while (($line = fgets($handle)) !== false) {         // process the line read.     }      fclose($handle); } else {     // error opening the file. }
