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

You should use count to count the number of items in an array, not print_r. What if output of this large array was aborted because of timeouts or something else? Or some bug/feature in print_r?
