Truncating Variable Values Can't Post
How can I truncate a variable value? Say I have the variable $url

the value to $url = "http://bobs_house.somelamewebpagehostingsite.com/~bob/joe/cat/jon/21541c.html";

I only want the first 25 characters of $url, after the 25th character, add "..." and remove characters 26 and up

Thanks,

Aaron

You want to use the substr(); function,

First you should check to see if there are more than 25 characters though, you can use length(); for that.

if (length($variable) > 25){
$variable = substr($variable, 0, 25);
$variable .= " ....";
}
