I have written an *evil* little function that will cut a string on a character given. Features:
1) Minimum length.
2) If a string doesn't contain the character, it cuts your string to minimum length.
3) If the next character beyond the minimumlength equals the given character, it will cut the string
to minimulength as well.
Code:
<?php
function cuttext($tring,$cuton) {
/* Define the character to cut on */
/* One could make an array with all characters to cut on */
/* But I wouldn't know how to :) */
$space=" ";
if (!strstr($tring,$space)) {
/* No space is found in the whole string: cut at 20th character */
$tring=substr($tring,0,$cuton);
}
if (substr($tring,$cuton,1)==$space) {
/* 21st character is a space: cut at 20th character */
$tring=substr($tring,0,$cuton);
} else {
/* 21st Character is NOT a space: return to last space and cut there */
while ($teller <= $cuton) {
if (substr($tring,$cuton-$teller,1)==$space) {
$tring=substr($tring,0,$cuton-$teller);
break;
}
$teller++;
}
}
return $tring;
}
echo(cuttext("waf groink muha zz gruu wrrreea iii gargghhh >:)>:)",20));
?>
