JS code:

Function init () {var Sys ={}; var ua = navigator. userAgent. toLowerCase (); var s; (s = ua. match (/msie ([\ d.] + )/))? Sys. ie = s [1]: (s = ua. match (/firefox \/([\ d.] + )/))? Sys. firefox = s [1]: (s = ua. match (/chrome \/([\ d.] + )/))? Sys. chrome = s [1]: (s = ua. match (/opera. ([\ d.] + )/))? Sys. opera = s [1]: (s = ua. match (/version \/([\ d.] +). * safari /))? Sys. safari = s [1]: 0;/* check the browser * // example: if the browser is Google, IE, or safari, what operations should you perform if (Sys. chrome | Sys. safari | Sys. ie) {// your operations }}

The above describes the browser used to determine the client, including the content, and hope to be helpful to friends who are interested in PHP tutorials.
