Search for portion of array help

[TCovert]

I am using the following code to determine if a string is in a part of an array element. However, I find that if the string that I am searching for is in the first array element, it doesn't find it, and assumes it isn't there. Anyone have any ideas on how to remedy this?

The Code:

array_search() must match the whole value, not just a portion. To search for a portion, use:

<?php
$myarray = array("some apples", "some bannanas", "some oranges");

function array_search_bit($search, $array_in)
{
foreach ($array_in as $key => $value)
{
if (strpos($value, $search) !== FALSE)
return $key;
}

return FALSE;
}

$searchkey = array_search("oranges", $myarray); //old function, returns FALSE
$searchkey = array_search_bit("oranges", $myarray); //new function, returns 2
?>

Really? Worked just fine for me:

$searchkey = array_search_bit('apples');
var_dump($searchkey); // int(0)

Yeah, still can't get it to find anything in that first record, but it works fine for every record after that. I am using php 5.1.6.

What I am doing is pulling records from a db, searching to see if the db record id is in the array, and then if it isn't, I delete the record, if it is, I do nothing.

The array is built from a text file, where each line is an element of the array.

I can't figure out why it doesn't see that first element. Very weird.

You might have to show us the actual application of this code. Also, can you show us a sample of the array you're matching against?

Here is the code:

function array_search_bit($search, $array_in)
{
foreach ($array_in as $key => $value)
{
if (strpos($value, $search) !== FALSE)
return $key;
}

return FALSE;
}

$coll_check_sql = mysql_query("select paper_ad_no, db_id from collectibles_data where interface_type = 'Class_Coll'");
$coll_check_num = mysql_num_rows($coll_check_sql);

for($c=0; $c<$coll_check_num; $c++){
$coll_check_row = mysql_fetch_array($coll_check_sql);

$coll_searchkey = array_search_bit($coll_check_row[paper_ad_no], $file);
if($coll_searchkey != ''){
} else {
$coll_del_sql = "delete from collectibles_data where paper_ad_no = '$coll_check_row[paper_ad_no]'";
$coll_del_result = mysql_query($coll_del_sql);
$coll_del_ph = mysq_query("delete from collectibles_photo where db_id = '$coll_check_row[db_id]'");
system("rm /home/kitsapsu/classifieds_photo_uploads/collectibles.$coll_check_row[db_id].*");
}

}

Here is part of the array (with no spaces between lines):
