May I know where that information is located? I didn't see it in manual
(chm-version, May 11 2003).
in_array:
"Searches haystack for needle and returns TRUE if it is found in the
array, FALSE otherwise."
And there is also mention about that strict-parameter
array_search:
"Searches haystack for needle and returns the key if it is found in the
array, FALSE otherwise"
"This function may return Boolean FALSE, but may also return a
non-Boolean value which evaluates to FALSE, such as 0 or ""."

There is not bug. (documented behaviour)

Yes, I know that strict-parameter, but I still think this isn't how it
should behave. In my opinion it shouldn't stop going through the array
when it finds zero and especially because it's telling misleading
information. Now I'm forced to use that strict-parameter to make it
behave in right and predictable way.

See the manual entry for in_array (3rd argument).

Hi!
I think I found a bug. I had a array where one of the values were zero
and I tried to search with in_array and later also with array_search if
there is a string for example "-". I expected them to tell me if the
string is in array, but the result was always same wether or not there
was searched string and it was that they gave me answer true when
checking with in_array and when checking with array_search it gave me
location of that zero value. Here is a sample code snippet the fiddle
with:
<?php
$test=array(0,"*",1,"+",2);
if (in_array("-",$test)) print"string bug!\n";
if (in_array("abc",$test)) print"string bug!\n";
$test=array(1,"*",0,"+",2);
if (array_search("-",$test)) {
print "string buugie!\n";
$value=array_search("-",$test);
print "Value is $value.";
}
?>
I tried it with longer strings and it behaved same way as told above. I
checked also with other types of variables as a needle but they worked
fine.
