[SOLVED] in_array not working...

[Ninjakreborn]

I have an array.

$array[1]['primary_domain'] = 'value1';

$array[2]['primary_domain'] = 'value2';

$array[3]['primary_domain'] = 'value3';

$array[4]['primary_domain'] = 'value4';

$array[5]['primary_domain'] = 'value5';

$array[6]['primary_domain'] = 'value6';

$array[7]['primary_domain'] = 'value7';

$array[8]['primary_domain'] = 'value8';

$array[9]['primary_domain'] = 'value9';

$array[10]['primary_domain'] = 'value10';

 

Then I have a standard string...might be...

variable = 'value5';

I need to simply do

if (!in_array($variable, $array)) {
// add variable into array if it's not there.
}

 

So far this has been working perfectly. But recently there is one "item" that isn't working property...and I am wondering why.  Is this standard behavior suppose to work or is there something wrong in my implementation?

i have had issues with in_array and multidimensional arrays... i use this function instead...

 

this is a very simple function and will only support 2 dimensions

 

function in_marray($needle, $haystack)
{
foreach($haystack as $x)
{
	if(in_array($needle,$x))
		return true;
}
return false;
}

when using $array with in_array() it looks at just the values of $array...which is 10 different arrays. it doesn't look any deeper then that. in each item of $array, you have another array. That array has an item with a key of 'primary_domain' in it...are there other keys or is this the only one?

This is the only key for now. I am trying to change the array structure to see if it will work then I am going to try foodigi's function as well and see how that goes in just a bit.

the problem with the in_marray() is it can be a waste of resources. as long as your arrays stay small it's fine...you may want to modify it a bit for your case though:

function my_in_array($key, $needle, $haystack)
{
  foreach($haystack as $item)
  {
    if($item[$key] == $needle)
      return true;
  }
  return false;
}

if (!my_in_array('primary_domain', $variable, $array)) {

}

Hmm. I tried that guys original function and it was a good idea. I was worried about performance. Thanks for that modified function.
