What's the maximum number of keys for an array in php

Question

I\'m writing a php script where I call

$lines = file(\'base_list.txt\');

to break a file up into an array. The file has over 100,000 lines in

Answer 1

Is it possible there is an inherent limit on the output from print_r. I'd suggest looking for the first and last line in the file to see if they are in the array. If you were hitting a memory limit inserting into the array you would never have gotten to the print_r line.
