[SOLVED] array search

[iversonm]

so far i have

$array = array(0 => array('blue', 1), 1 => array('red', 2), 2 => array('green', 3), 3 => array('red', 4));

$key = array_search('green', $array); // i want $key=2
echo $key;//should echo 2 but it echos nothing 

 

how do i get this to work,

I think you will have to loop through each array and search them individually.

That's because you have a multidimensional array. Just create a custom search function since you are using a custom array

 

function search_myarray($search_val, $input_array)
{
    $return_val = false;

    foreach($input_array as $key => $sub_array)
    {
        if ($sub_array[0]==$search_val)
        {
            $return_val = $key;
            break;
        }
    }
    return $return_val;
}

$array = array(
0 => array('blue', 1),
1 => array('red', 2),
2 => array('green', 3),
3 => array('red', 4)
);

$key = search_myarray('green', $array);
echo $key; //Will echo 2

hrm.... let see if i had to scale how well that worked from 1 to 10 it would most definaitly be a 12 so i thank you, it does exactly what i want it to

 

thankyou mjdamato

I would add...

 

There might be a reason why you are contructing your array in that manner, but unless the the key of the first array value and the numeric value in the secondary array are unique values that you really need (e.g. 2 & 3 for green), I would suggest creating your array like this:

$array = array(
1 => 'blue',
2 => 'red',
3 => 'green',
4 => 'red'
);

well i just added the numbers in to show that it was array inside an array and if the second array only had 1 object then it would be pointless to have a second array but inside each second array is about 50 variables that all need to be accounted for sooo i couldn't just use array array_multisort like before but thanks for the input
