Replacing a value inside array

That's driving me nuts, can't figure it out.

$input = array("red", "green", "blue", "yellow");

Code (markup):

Trying to replace green with apple.

EDIT:

Seriously, I've been looking into array_slice for at least 15 minutes and it just didn't work. Well, now I figured it out. Sorry again for the waste of bandwidth

 

I don't think there's a PHP function to simply replace a value with another value. Values have to be modified or assigned. All array_slice does is return the values of an array between the first and second parameters.

I think this is the shortest way...

$green_key = array_search('green', $input); // returns the first key whose value is 'green'
$input[$green_key] = 'apple'; // replace 'green' with 'apple'

PHP:

Technically, simply going $input[1] = 'apple' would work if 'green' is always in the second spot

 

Or:

<?php
$input = array("red", "green", "blue", "yellow");
$needle = "green";
$replacement = "apple";
for($i=0;$i<count($input);$i++) {
   if($input[$i] == $needle) {
   $input[$i] = $replacement;
   }
}
?>

PHP:

Array_search is pretty heavy on the server load, ( increases parse time ), so i tend to use loops more.

 

Yes, definitely a great way to do it. Gonna use that instead of array_slice. Thank You

 

No problem . Array_slice is, as the name says, for slicing arrays and not replacing elements of an array.
