Manipulating/Changing keys in an Multidimensional array.

Copy linkTweet thisAlerts:
Mar 15.2008

Hello,

I need a way to change keys in an array. For example if the key of a certain element is “0” I need it to be “look”. Now, I know there is array_flip. But I do not think it will work for a multidimensional array, as I only want to change the keys on the 2nd dimension.

I was wondering if foreach would work for this, as it can use $keys. However when I tried to do it, it didn’t work. At least it did not save they $keys onto array.

There is a certain site that talks about it. However if asks you to pay.

Any help would be appreciated.?

Thank You

@bokehMar 15.2008 — I'm not really sure what you are asking.

[code=php]$array['look'] = $array[0];
unset($array[0]);[/code]

$anarray = array(0=> "hol");

Then I want to change the "0" to something else.

Would what you just said work?

@bokehMar 15.2008 — What do you want to change: the key or the value?

@DragonkaiauthorMar 22.2008 — It works thanks, but I had to first get my head around it.

If anyone else needs information for this.

Basically:

Example:

$endtypearray[$tensecolumnarray[$key]] = $endtypearray[$key];

unset ($endtypearray[$key]);

If I had an array with the values : look,see,hah. This is $tensecolumnarray.

And I had another array that I wanted to replace the keys with the values in $tensecolumn array which is the $endtypearray;

I foreached the $endtypearray with $key => $value and then used the "Example" to change the keys in the $endtypearray to the values in the $tensecolumnarray.

So what's happened is it has added a new element to $endtypearray which uses a different name specified by $tensecolumnarray which is equal to the original key's element. Then it unsets the one that I wanted to replace.

Very smart.

Success!
