PHP.JS is an open source project in which to port PHP functions to JavaScript. The library is developed by Kevin van Zonneveld and his contributors, and they have been working hard in adding more functions into it. By including this library into your own web projects, you can use those higher-level PHP functions such as file_get_contents(), mktime(), serialize(), etc which JavaScript doesn't support them natively.
Here is a piece of sample code of PHP's encryption function: base64_encode():
function base64_encode( data ) {
var b64 = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=";
var o1, o2, o3, h1, h2, h3, h4, bits, i = ac = 0, enc="", tmp_arr = [];
data = utf8_encode(data);
do {
o1 = data.charCodeAt(i++);
o2 = data.charCodeAt(i++);
o3 = data.charCodeAt(i++);
bits = o1<<16 | o2<<8 | o3;
h1 = bits>>18 & 0x3f;
h2 = bits>>12 & 0x3f;
h3 = bits>>6 & 0x3f;
h4 = bits & 0x3f;
tmp_arr[ac++] = b64.charAt(h1) + b64.charAt(h2) + b64.charAt(h3) + b64.charAt(h4);
} while (i < data.length);
enc = tmp_arr.join('');
switch( data.length % 3 ){
case 1:
enc = enc.slice(0, -2) + '==';
break;
case 2:
enc = enc.slice(0, -1) + '=';
break;
}
return enc;
}
The library is available in 2 different packages:
