Restrict the number of characters in output

[buzzt]

I need to use PHP to get the string length [which I already have with strlen()] and trim off any characters after a certain length. In other words, if the word PURPLE was returned from the query, and I wanted to restrict the number of chracters to 4, then the output would actually read PURP... and not PURPLE.

Any ideas?

use substr($string, int start [, int length])

where $string is the string to be trimmed

start is an integer that is the starting location (ie 0 for begining of word etc)

length is the length of the string to be taken from the start position

I guess with PHP 5 you can use the str_split(), but I found a function for earlier versions.

Function str_split($string, $chunksize=1)
{
preg_match_all('/('.str_repeat('.', $chunksize).')/Uims', $string, $matches);
return $matches[1];
}

$str=PURPLE
$trim=str_split($str, 4);
echo $trim[0]; //This will echo the first 4 characters.
