Bug description:strpos('49,35',35) ==> FALSE
Description:
------------
strpos ($string, $number) returns FALSE, whereas
strpos ($string, (string) $number) returns the first occurrence of the
(stringified) number. The same is true for older versions of PHP.
May be this is intended, but a small comment about this behaviour would
be helpful.
The real problem is that (during the reading of configuration files or
database values) sometimes an automatical conversion takes place, so
that $number, which needs to be interpreted as a string in the example
above, is instead interpreted as numerical value. This leads to problems
in some programs, which (e.g.) search for a number in a comma-separated
list of numbers.
Without knowing the behaviour of 'strpos()', one may sometimes search
hours and hours for a problem which could be solved with a simple remark
in the documentation.
Test script:
---------------
<?php
$a = '49,35'; $b = 35; $c = (string) $b;
print "strpos('$a', '$b') = ".strpos($a, $b)."\n";
print "strpos('$a', '$c') = ".strpos($a, $c)."\n";
?>
