strstr

[lukezweb]

how do you remove the last two letters of a string?

i know u can get them by using strstr() with -2 but how do you remove them say from this....


$test="test";
$test2=remove last two letters;
echo "$test2";

which then gives 'te'

[piersk]

$test2 = substr($test,0-2);

I think...

You forgot a comma in there, Piers. ;)

$test2 = substr($test, 0, -2);

<?php
while ($row = mysql_fetch_array($users))
{
$foo = substr($row['username'], 0, -2);
echo "".$foo.", ";
}
?>

not sure if this is what you wanted. i didn't really understand what you meant.

you removed the last two from username list, i want to do what ive doen but maybe instead of echo i add strstr in so after putting in all the username (this is an sql statement) it removes the last , as it adds a , and a space after each right now :)
