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 memo

Answer 1

There is a file() function that returns an array of the lines contained in the file.

foreach(file('myfile.txt') as $line) {
   echo $line. "\n";
}
