Here is a way to chop a string (long text to short text) without cutting it in the middle of a word
but still based on total string lenght;
It will try to make the string as close as $maxlen as possible - result will not be greater (in
length) than $maxlen+$maxoverflow - If the next word to be injected exceed $maxoverflow, the final
length will be smaller than $maxlen. $elli is used to append something to a chopped result (eg.:
"...")
strtrim("hello world, this is a string cutter!", 25, 15, "...");
function strtrim($str, $maxlen=100, $maxoverflow=15, $elli=NULL) {
if (strlen($str) > $maxlen) {
$output = NULL;
$body = explode(" ", $str);
$body_count = count($body);
$i=0;
do {
$output .= $body[$i]." ";
$thisLen = strlen($output);
$cycle = ($thisLen < $maxlen && $i < $body_count-1 &&
($thisLen+strlen($body[$i+1])) < $maxlen+$maxoverflow?true:false);
$i++;
} while ($cycle);
return $output.$elli;
}
else return $str;
}
- Result should be: hello world, this is a sting ...
- If the word "string" would have been longer than $maxlen, result would have been
"hello world, this is a ..."
- $elli is not appended if the string does not need to be cutted.
