[SOLVED] Explode(), simple question

[chmpdog]

Hola,

 

Im trying to md5 encrypt an exploded string, then implode the string. And finally echo the encrypted string(seperated by ,) But I dont know where to go from this:

$str = 'thing,thing2,thing3,thing4';
$change = explode(",", $str);

Is there a tutorial,

Thanks

to show echo of the explode you need to define which position you want to show ie

 

<?php 
echo $change[3];
?>

 

would output

 

thing 3

you could use a foreach to loop over the elements, but i decided to use array_walk:

<?php
$str = 'thing,thing2,thing3,thing4';
$list = explode(",",$str);
array_walk($list,create_function('&$v','$v = md5($v);'));
$str = implode(",",$list);
print $str;
?>

cool, that works.

 

Thank you
