This is a bit screwy...
First, array_search returns an array of keys where the values are
exact matches... while you want to match a substring (I think);
Then, it searches through the array again using regular expressions,
and each time it finds something, it over-writes all previous values...
and if there were any matches to begin with, it WILL find them again.
And why is the search-string passed as a global while the
array is passed by value?! This makes no sense to me.
Finally, result is passed back as a string after being munged
so it can't be used as a key - and if nothing was found, it returns
a string consisting of a single space.
Try one of these instead:
// util function: case-sensitive search for substring,
// returns true if found, else false
function findSameCase($haystack, $needle) {
return (strpos($haystack, $needle) !== false);
}
// util function: case-insensitive search for substring,
// returns true if found, else false
function findAnyCase($haystack, $needle) {
return (strpos(strtolower($haystack), strtolower($needle)) !==
false);
}
// return the key of the first array member containing the search string,
// or false if there are no matches.
function findFirst($arr, $string, $caseSensitive=false) {
if ($caseSensitive)
$find = "findSameCase";
else
$find = "findAnyCase";
foreach($arr as $key => $val)
if ($find($val, $string))
return $key;
return false;
}
// return an array of all keys to members containing the search
// string (if there are no matches, the array is empty).
function findAll($arr, $string, $caseSensitive=false) {
if ($caseSensitive)
$find = "findSameCase";
else
$find = "findAnyCase";
$result = array();
foreach($arr as $key => $val)
if ($find($val, $string))
$result[] = $key;
return $result;
}
