[RESOLVED] Remove an element from an array

jdc44

Greetings all,
I'd like to know if there is a way to remove an element from within the center of an array, not the first or last element?

Example:

$fruit = array('apple', 'banana', 'peach', 'pear');
foreach( $fruit as $key => $val ){
   if( $val == 'banana' ){
       // remove $fruit['banana']  ????
   }
}

Is there a simple means to accomplish this?
Thanks for any help.

Cheers!

One way:

$remove = 'banana';
$fruit = array_filter($fruit, create_function('$val', 'return($val != "' . $remove . '");'));

<?php

$fruit = array('apple', 'banana', 'peach', 'pear');
foreach( $fruit as $key => $val ){
   if( $val == 'banana' ){
       unset( $fruit[$key] ); //takes away index
   }
}
echo '<pre>';
print_r($fruit); // show the resulting array

This works, too.
Result

Array
(
    [0] => apple
    [2] => peach
    [3] => pear
)

One little problem is how to get keys to be 0,1,2
I do not remember how to do .......

How can we get to here??????

Well, the first question will be, "Does it matter?" If you are using numeric indexes like that which do not have any intrinsic meaning, then the need for them to be sequential is only needed for something such as doing a for() loop by index. If you are going to use something like foreach() which does not care if they are sequential, then it does not matter.

So, if you do need them to be sequentially numbered, you can do:

$array = array_values($array);

Weedpacket

array_diff($array, array('banana'));

Clarification needed: if there are multiple instances of the value to be removed, should all of them be removed or some of them or just one? If so, which?

Thanks NogDog. array_values() it is

Thank you all for your help. It is great and much appreciated. I knew of the unset method and did not think of it - obviously.

thanks for the reminder.

As for the indexing order, that does not apply to me in my situation. I'm actually using an associative array.

Resolved!

Thanks again.
