get first letter of string..
is there a way of getting the first letter of a string?

I have a few images which begin with "t_" -- this is so that I can do a search and not show any files which begin with "t_"..

eg:

if (file begins with "t_")
{
dont show it
}
else
{
show it
}

any thoughts??

thanks...

substr($var, 0, 2);

That should get the first 2 characters of a string.

Or ->
PHP Code:
 $string = 't_2536_file.jpg';
if ( ( $string[0] == 't' ) && ( $string[1] == '_' ) ) {
   dont show it
} else {
   show it
}

cheers ben, that worked perfectly!



Any ideas on how I might remove the "T_" from the string?
I use:

PHP Code:
 $filename = ereg_replace("_", " ", $data_pair[0]);
$tmp = ereg_replace("\n", "", $data_pair[0]); 


to remove the "_" and line breaks... but I'm not sure how to remove the first two chars.....

thanks!!

if you're always supposed to remove only to chars from the beginning of a string, you can use: substr($var, 2)
