Subject: Use constant size string in hash bench.php
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=6c71d3476b695a92377505f2fd19ddc97418ef94;p=php

Use constant size string in hash bench.php

I don't like the previous behaviour where the bytes to hash change
every time the code changes, that may make it difficult to compare
hash() performance changes over time.

Use a fixed number instead, and allow passing an override for a
different length.

Closes GH-6386.
