Bug description: wrong return value for a key in function array_search
Description:
------------
I trying to get the fraction part of a decimal number using the string
keys of an array as a lookup table.
Example: 4.25 -> 4-1/4
I sending argument 25 to function 'ConvToFrac'
and getting the corresponding key value ('1/4' for this case).
Reproduce code:
---------------
echo ConvToFrac('0625');
function ConvToFrac($value) {
$frac_conv =
array('1/2'=>'5','1/4'=>'25','3/4'=>'75','1/8'=>'125','3/8'=>'375','5/8' =>
'625',
'7/8'=>'875','1/16' =>
'0625','3/16'=>'1875','5/16'=>'3125','7/16'=>'4375','9/16'=>'5625','11/16'
=>'6825',
'13/16' =>'8125','15/16'=>'9375');
$key = array_search($value, $frac_conv);
return $key;
}
Expected result:
----------------
I expecting '1/16' for argument '0625'
Actual result:
--------------
I'm getting '5/8'
the search can not differentiate between array string key '625' and
'0625'.
