Solving the _php basis of the string length problem in Chinese and English

Copy Code code as follows:

function Strsplit ($s, $len) {
$end = ' ... ';
$result = ';
$strLen = StrLen ($s);
if ($strLen <= $len) {
return $s;
}
$len-= 2;
For ($i =0 $i < $len && $i < $strLen; $i + +) {
$c = $s [$i];
if (Ord ($c) < 0x80) {
$result. = $c;
} elseif ($i +1< $len) {
$result. = $s [$i + +]. $s [$i];
}
}
Return ($i < $strLen)? ($result. $end): $result;
}

echo strsplit (' 1234567 ', ten), ' <br/> ';
echo strsplit (' 1234567890 ', ten), ' <br/> ';
echo strsplit (' 1234 Chinese 567890abcdefghijkl ', ten), ' <br/> ';
Echo Strsplit (' All are Chinese ', ten), ' <br/> ';
Echo Strsplit (' All a part B all C is D medium e ', ten), ' <br/> ';
