strtolower an array

JCScoobyRS

Can someone help me create an array ($array2) out of another array ($array1) but make the words in ($array2) the same as the words in ($array1) but all lower case? Thanks, Jeremy

<?php
$array1 = array("Hello","World");
$array2 = array()
foreach($array1 as $key=>$value){
	$array2[$key] = strtolower($value);
}
print_r($array2);
?>

Here is some code that I need to modify to work with case insensitive comparison:

//Loop through each word
for($cntWord=0; $cntWord<Count($lineWords); $cntWord++){
     //Process each word
     if (array_key_exists($lineWords[$cntWord],$KWarray)){

 $lineWords[$cntWord] = '<span style="'.$KWColor[$KWarray[$lineWords[$cntWord]]].'">'.$lineWords[$cntWord].'</span>';

 }
}

What I need to do is modify the line starting with if( to fit what you have presented me with. Thanks, Jeremy

P.S. - The way the array looks is as follows:

$this->keyWords = array(
     "End" => "0",
     "Private" => "0",
     "Sub" => "0");

This complicates things since the words being compared are actually array keys. Thanks, Jeremy

$field[0] = strtolower($field[0]);
$field[2] = strtolower($field[2]);
$field[3] = strtolower($field[3]);
$field[4] = strtolower($field[4]);

The reason why is I am working on a module for a CMS that let's forums allow for code syntax highlighting. I'm basically creating an array of lines from an exploded TextBox. Then I loop through each line and create an array of words by exploding the line. Then, I look through each word and compare it to an array (key) and then go along my way. You are seeing the portion where I'm looping through the words and comparing. So...is it possible to do what I need? Thanks, Jeremy

Um... just strtolower() the array key... and be on your marry way.

You should have been able to figure that out on your own...

Ok.....how do I do that? If I do:

strtolower($array), the keys aren't effected. How can I do this?

Who are you to tell me what I "should" know? You don't know me. The people in this forum are so rude some times. It's not like that in Java Forums or Visual Basic Forums. I know there is a manual, which I read, and it tells me nothing regarding this. Lighten up!

$array1 = array ("FIRSTNAME" => "Keith", "LASTNAME" => "Palmer");

$array2 = array ();

foreach ($array1 as $key => $value) {
$key = strtolower ($key);
$array2[$key] = $value;
}

Happy now? Seriosly, that wasn't that hard to figure out...

Seeing that I am new and it's not an example I've found yet, it is a bit harder to me. You gotta realize that if I knew the answer, I wouldn't had asked. I'm sorry if I got a bit pissy earlier but this PHP Forum is the worst as far as friendly support as most people say "RTFM" or something to that effect. I understand that many people do post here without reading or searching first but many do so please don't assume that it's an easy answer just because it's easy to you. Hopefully no hard feelings, Jeremy

BTW...thanks alot.

Really now, what that necessary?
What crawled up your arse? To those of us that are new to PHP, IT WASN'T ALL THAT OBVIOUS...... Lighten up... it's not like you were being forced to help.... Yeah, we probably could have figured it out eventually, but several hours had already been spent on the issue and it wasn't going anywhere..... It's people like you some times that make me wonder why I even bother sometimes....
Don't get me wrong, gratefull for your help, but your "bedside manner" leaves a bit to be desired....
