[SOLVED] Newbie - got a problem with ltrim

[colinsp]

I have a little problem. I have searched the php manual and a couple of books without success. I am trying to get my head round the ltrim command.

 

Say I have a variable and it contains 12345-ABCDEF and I just want to assign the letters to another variable the code I have tried is

 

$one ="12345-ABCDEF";
$two = ltrim($one, "-");
echo $two"\ n";

 

I still get 12345-ABCDEF instead of ABCDEF so it has to be me not understanding how this function works properly. Is this the proper way to do this or is there a better way?

 

TIA for any suggestions.

i would use explode() instead and make it an array.

 

<?php
$string = "12345-ABCDEF";
$parts = explode("-",$string);

echo $parts[0]; // 12345
echo $parts[1]; // ABCDEF
?>

All ltrim does is remove whitespace from the left side of the string.

What you need is to use substr() to get a substring or use preg_match() to extract the non numeric part or break up the string using the hyphen i.e. explode()

Thanks very much to both of you for the information. I have used explode and it works fine.

 

Nothing like using a hammer when you should have used a screwdriver.
