in_array

jayrod_84

if (!in_array($fname, $info['name'])){ 
array_push ($info[name], $fname);
}

If $fname is not in the array $info['name'] then I want to add it to it.

What I was hoping is that the above code would search an array and add an object to it only once..

Where is the flaw at? for some reason it either add's everything or nothing.

Is $info['name'] an array? I assume you are using a 2D array. Are you searching for a particular key or value? The in_array() function searches values, not keys.

<?
if (!in_array ($fname, $info['name'])) {
$info['name']['fname'] = $fname;
}
?>

If you want to search keys:

<?
if (!isset ($info['name']['fname'])) {
$info['name']['fname'] = $fname;
}
?>

you really don't need array_push() for this since you are only adding one element.

//** 2D array
$info = array(
    "name" => array (),
    "total" => array ()
    );

i'm adding names to the "name" array.

and i'm searching on value.. I think.. i'm a little hazy as to the difference between key and value.

In PHP (as opposed to PERL) all arrays are "associative arrays". That is to say that each array element has 2 parts: key and value. Think of it as a name/value pair:

key: value:
'first' 'John'
'name' 'Michael'
'last' 'Smith'

If you are searching for a value use in_array(). If you are seaching for a key use isset() or array_key_exists().

I am looking for a value. I believe that i've pushed a value onto the array correctly.

now the question is.. have I pushed a value.. or a key upon the array?

You have pushed both. All array indexes have both key and value. If you don't specify a key then a numeric key will be used automatically (starting with 0):

$array[] = 'John';
$array[] = 'Joe';
$array[] = 'Jim';
$array[] = 'James';
$array[] = 'Jimmy';

$array now looks like this:
[0]['John']
[1]['Joe']
[2]['Jim']
[3]['James']
[4]['Jimmy']
