小白请教大佬,js函数转成php代码。
[ol]function utf16to8(str) { var out, i, len, c; out = ""; len = str.length; for(i = 0; i = 0x0001) && (c 0x07FF) { out += String.fromCharCode(0xE0 | ((c >> 12) & 0x0F)); out += String.fromCharCode(0x80 | ((c >> 6) & 0x3F)); out += String.fromCharCode(0x80 | ((c >> 0) & 0x3F)); } else { out += String.fromCharCode(0xC0 | ((c >> 6) & 0x1F)); out += String.fromCharCode(0x80 | ((c >> 0) & 0x3F)); } } return out; } var base64EncodeChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";function base64encode(str) { var out, i, len; var c1, c2, c3; len = str.length; i = 0; out = ""; while(i > 2); out += base64EncodeChars.charAt((c1 & 0x3) > 2); out += base64EncodeChars.charAt(((c1 & 0x3)> 4)); out += base64EncodeChars.charAt((c2 & 0xF) > 2); out += base64EncodeChars.charAt(((c1 & 0x3)> 4)); out += base64EncodeChars.charAt(((c2 & 0xF) >6)); out += base64EncodeChars.charAt(c3 & 0x3F); } return out; } [/ol]复制代码 |
