Array Question I am stuck on this one

[Nitronic]

Lets say you have a array declared like this


<?php

$Array=array("D rum & Bass","Jungle", "House","Techno ","Hip Hop");

?>



but what i want do do is somehow using a for loop to remove items in the
array. The items i want to remove are 0,2,4 or just 2,5. Deleting a item
in the array has to be flexible at which item to delete.


I appreciate anybody helps me on this thanks very much :)

Re: Array Question I am stuck on this one

To remove item $Array[4]:

unset($Array[4]);

Note that this will not re-index the array continuously -- you'll just
have buckets with null values.

If you want to re-index the array, use:

array_merge($Ar ray);

Thanks but what if this were the case

<?php

//Items in Array One
$Array=array("D rum & Bass","Jungle", "House","Techno ","Hip Hop");

//Remove Array

$Array_removeIt ems=array("0"," 2","4");

?>

How would i remove items in Array One with the items specified in the other
array. Note in Array_removeIte ms the values can change also.

Thanks a million :)

//Items in Array One
$Array=array("D rum & Bass","Jungle", "House","Techno ","Hip Hop");

//Remove Array
$Array_removeIt ems=array("0"," 2","4");

for($i = 0; $i < count($Array_re moveItems); $i++)
unset($Array[$Array_removeIt ems[$i]]);

or

foreach ($Array_removeI tems as $i)
unset($Array[$i]);

(still surprised by the number of times I see this C-style for loop
instead of a foreach loop)
