Truncate long text with PHP (excerpt function)

Truncate is a handy function which can truncate a long text into specific length string and adds elipsis (...) after it.
This is an example of how the function "truncate($text,47)" works :
Before
CODE:
-
This is a very long text that I type as an example to show you the functionality of truncate
After
CODE:
-
This is a very long text that I type as an exam....
Here's the PHP code that can let you do just that :
PHP:
-
function truncate ($str, $length=10, $trailing='...')
-
{
-
/*
-
** $str -String to truncate
-
** $length - length to truncate
-
** $trailing - the trailing character, default: "..."
-
*/
-
// take off chars for the trailing
-
{
-
// string exceeded length, truncate and add trailing dots
-
}
-
else
-
{
-
// string was already short enough, return the string
-
$res = $str;
-
}
-
-
return $res;
-
-
}
Truncate as an excerpt function
Truncate can be use to create excerpts from a very long text to serve as a preview or summary on your PHP application.
