remove item from array by key

[dmikester1]

I can't figure out how to remove a specific item from my array by key.

Array:

$uncachedSites = array(2=>'site 1', 3=>'site 2', 4=>'site 3', 5=>'site 4');

 

So I'm running through a loop with $i starting at 2 and going up to 5. If I say unset($uncachedSites[$i], the first time around I'm thinking it will remove 'site 3' instead of 'site 1' like I want it to. But I can't figure out how to remove the first one without just saying unset($uncachedSites[0])

Thanks

did you try it?

 

$uncachedSites = array(2=>'site 1', 3=>'site 2', 4=>'site 3', 5=>'site 4');

for ($i=2; $i<=5; $i++)
{
   if ($uncachedSites[$i]=='site 1') unset($uncachedSites[$i]);
}

echo '<pre>',print_r($uncachedSites, true),'</pre>';

/* results ****
Array
(
   [3] => site 2
   [4] => site 3
   [5] => site 4
)

Or, you could use array_shift (). Saves you from having to know and test the value.
