将多维数组中的数组值与索引进行比较

I have a multidimensional array that loks lik this:

Array
(
[0] => Array
    (
        [name] => >chr1:2198584545754_genome_1000+
        [score] => 511
        [hit] => 50   

    )

[1] => Array
    (
        [name] => >chr2:2198581212154_genome_1000+
        [score] => 620
        [hit] => 80   

    )

[2] => Array
    (
        [name] => >chr3:2115151215754_genome_1000+
        [score] => 666
        [hit] => 90   

    )

[3] => Array
    (
        [name] => >chr4:2198584545754_genome_1000+
        [score] => 750
        [hit] => 50 

    )

[4] => Array
    (
        [name] => >chr5:1218455145754_genome_1000+
        [score] => 800
        [hit] => 100  

    )

[5] => Array
    (
        [name] => >chr6:1231354645454_genome_1000+
        [score] => 850
        [hit] => 110  

    )

[6] => Array
    (
        [name] => >chr7:1231213211134_genome_1000+
        [score] => 900
        [hit] => 120  

    )

 )                     

I have a foreach loop which will loop through each letter of a random sequence and use the index to give each letter a number value. If the value of ['hit'] matches the index value of the random sequence i want to insert a function.

I cannot figure this out. I think my problem is in callng each value of ['hit'] and comparing with index. Does anyone know how to do this ? thanks

To put DaveRandom's comment into an answer (with minor amends):

foreach ($outerArray as $index => $innerArray)
{
    if($innerArray['hit'] === $index)
    {
        doSomething();
    }
}

@DaveRandom - feel free to delete or re-post this as your own answer if I'm posting out of turn here...

       foreach ($array as $key) {

       if ($key['hit'] == $index)

        { 

      // you function or logic here

        } 

    }
