PHP Custom function to implement JS Escape method sample _php Tips

This example describes the PHP custom function to implement JS escape method. Share to everyone for your reference, specific as follows:

php function function Escape ($string) {$n = $bn = $tn = 0;
    $output = ';
    $special = "-_.+@/*0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZABCDEFGHIJKLMNOPQRSTUVWXYZ";
        while ($n < strlen ($string)) {$ascii = Ord ($string [$n]); if ($ascii = = 9 | | $ascii = 10 | | (<= $ascii && $ascii <= 126))
        {$tn = 1; $n + +;
        } elseif (194 <= $ascii && $ascii <= 223) {$tn = 2; $n + = 2;
        } elseif (224 <= $ascii && $ascii <= 239) {$tn = 3; $n + = 3;
        } elseif (<= $ascii && $ascii <= 247) {$tn = 4; $n + = 4;
        } elseif (248 <= $ascii && $ascii <= 251) {$tn = 5; $n + = 5;
        } elseif ($ascii = = 252 | | $ascii = = 253) {$tn = 6; $n + = 6;
        else {$n + +;
        } $singleStr = substr ($string, $bn, $tn);
        $charVal = Bin2Hex (Iconv (' utf-8 ', ' ucs-2 ', $singleStr)); if (Base_convert ($cHarval > 0xFF) {if (!preg_match ("/win/i", php_os)) $charVal = substr ($charVal, 2, 2). s
          Ubstr ($charVal, 0, 2); $output. = '%u '.
        $charVal;
            else {if (false!== Strpos ($special, $SINGLESTR)) $output. = $singleStr; else $output. = "%".
        Dechex (Ord ($string [$bn]));
    } $bn = $n;
return $output;

 }
