[RESOLVED] Easy way to remove $x from database column text? Boolean subtract type function?

[listenmirndt]

Hi guys, I could probably figure out a way to do this, round-abouts, but I am wondering if theres an easy way to boolean subtract a string of text from another string of text in a database column.

IE.

$stringtoremove = ABCD;

$stringindatabase = ABCDEFGH;

So that $stringindatabase would equal EFGH

Thanks!

I think you could use str_replace where you just replace with an empty string,
i.e.

$stringindatabase = str_replace($stringtoremove, "", $stringindatabase);

I have not tested myself which normally means that there is a bug in the above expression (just looking at my earlier trackrecord)

it sepnds on what you want

$oldstring = 'ABCDEFGH';

1. do you want to always remove 'ABCD', use igorlopez way
   $newstring = str_replace( 'ABCD', '', $oldstring );

2. you always want to remove the first 4 characters
   $newstring = substr( $oldstring, 4 );

See manual:
[man]str_replace[/man]
[man]substr[/man]
