Php implementation of the escape and unescape functions in javascript
Escape function
- /**
- * Js escape php implementation
- * @ Param $ string the sting want to be escaped
- * @ Param $ in_encoding
- * @ Param $ out_encoding
- */
- Function escape ($ string, $ in_encoding = 'utf-8', $ out_encoding = 'ucs-2 '){

Unescape code:
- Function unescape ($ str)
- {
- $ Ret = '';
- $ Len = strlen ($ str );
- For ($ I = 0; $ I <$ len; $ I ++)
- {
- If ($ str [$ I] = '%' & $ str [$ I + 1] = 'u ')

- $ Ret. = chr ($ val );
- Else
- If ($ val <0x800)
- $ Ret. = chr (0xc0 | ($ val> 6 )).
- Chr (0x80 | ($ val & 0x3f ));
- Else
- $ Ret. = chr (0xe0 | ($ val> 12 )).
- Chr (0x80 | ($ val> 6) & 0x3f )).
- Chr (0x80 | ($ val & 0x3f ));
- $ I + = 5;
- } Else
- If ($ str [$ I] = '% ')
