Explode

[The1corrupted]

I have a question about the explode function and am rather confused...
Say $msg=I like Corn
If I have [PHP]<?php
$mesg=explode(" ", $msg, 3);
echo $mesg[0].$mesg[2];
?>[/PHP]
will I manage to be able to pull this result:
"I like"?

What you are echoeing in your sample is "ICorn" because you used the first (msg[0]) and the third (msg[2]) entries without connecting blank character.

In order to display "I like" your do[php]echo $mesg[0].' '.$mesg[1];[/php]

Ah... Also, can I double explode strings? Say...

[PHP]
<?php
$mesg=explode(" ", $msg, 2);

if ($mesg[0]=="word") {
$mesg=explode(" ", $msg, 3);
}

?>[/PHP]
Or would I have to redefine $mesg in the if statement as another variable?

Use another variable for the array

 <?php 
$mesgArray1=explode(" ", $msg, 2);
 
if ($mesgArray1[0]=="word") {
$mesgArray2=explode(" ", $msg, 3);
}
?>
 

The value of $msg remains the same in this case
