[PHP-DEV] Re: PHP 4.0 Bug #3017 Updated: if(strpos("Mozilla/4.7", "Mozilla") evaluates false!!! From: Cuneyt YILMAZ (cu <email protected>)
Date: 12/21/99

thank you for the fast response. however the function still does not
behave as one would expect.

that strpos("Mozilla/4.7", "Mozilla") is 0 should not mean that it's not
found, instead should mean that it's found right on the 0th position,
and therefore in an if-clause should evaluate to true.

i know there are many workarounds to this problem, like
if (substr($uagent, 0, 7) == "Mozilla)) {
or
if (strpos($uagent, "ozilla") == 1 ) {
etc, etc

yet the strpos function still does not behave as expected, ie return -1
if not found as in the other languages, say C/C++, Java, JavaScript,
Perl, to name a few giants.

thank you anyway,
regards,
cuneyt yilmaz
