Deleting Value in Array.

WinterDragon

I am needing to delete the first occurence of an item in an array..
Such as this an array contains these items.

$array = array("One", "Two", "One", "Two");

$item = "Two";

How can I delete the first occurence of $item inside of $array, and only the first occurence?

So after that item was deleted it should only be "One, One, Two", so how would I do this?

Thanks for any help. 🙂

here is what i would try

$arr = array("One", "Two", "One", "Two"); 

$del="Two";

if(in_array($del,$arr)){
  unset($arr[array_search ( $del, $arr)]);
}

or maybe better would be...

$arr = array("One", "Two", "One", "Two"); 

$del="Two";

$idx=array_search ( $del, $arr);

if($idx || $idx===0){
  unset($arr[$idx]);
}

this way you don't search the array twice.

Parse error: parse error, unexpected T_CONSTANT_ENCAPSED_STRING line 2.

Whats up with that? 😛 I don't know um what that meant hehe.

hmm...i tested the code i posted up above and i didn't get any errors...

This worked...

<?php
$myArray = array("One", "Two", "One", "Two");
$delItem = "Two";
$check = array_search($delItem, $myArray);
unset($myArray[$check]);
foreach($myArray as $i) {
echo "$i<br>";
}
?>

of course the foreach() {} is just for me to view to make sure it worked... And it worked, although I couldn't have gotten that without you showing me those functions, I dunno why it was giving me those errors though. THANKS!!
