Find a regular expression and replace the emoticon of a rule with an emoticon icon (<img> emoticon)

Find a regular expression, replace the emoticon of a rule with the expression icon (& lt; img & gt; expression), and find a regular expression, replace a regular emoticons with emoticons (emoticons)

[Happy] is replaced by (the naming rules for images in Chinese are not standard ?)

In fact, it is better to use JS for comparison.

Reply to discussion (solution)

$ Str = '[happy] emoticon image ';
Echo preg_replace ('/\ [(. *) \]/', "", $ str );

This year, everything is regular...
It is not wise to use a Chinese name as a file name.

Function replaceStr ($ str ){
$ Str = substr ($ str, strpos ($ str, '[') + 1, strlen ($ str)-2 );
Return "";
}

How is the efficiency of replacing the entire page?

$ Str = '[happy] emoticon image ';
Echo preg_replace ('/\ [(. *) \]/', "", $ str );

It should be acceptable.

I found a JQ plug-in on the Internet and replaced it on the client. for English emojis such as [happy], they can be replaced, but once changed to [happy] Chinese emojis, they won't work. well, I also feel that the file name in Chinese is not good.

// jQuery Plugins: On/Off Emtions var __emotion__cache = false;jQuery.fn.emotions = function() {    var aEmotion = new Array();        aEmotion[21] = new Array('[happy]','\\[happy\\]');        __emotion__cache = true;    this.each(function() {        str = $(this).html();        for(iEM in aEmotion){            reg =  new RegExp(aEmotion[iEM][1],"ig");            str = str.replace(reg,'');        }        $(this).html(str);    });};jQuery.fn.unemotions = function(){    __emotion__cache = false;    $('.plugin_emotion').each(function(){        $(this).html(decodeURIComponent(this.title));                                       });}

Chinese file names are not compatible with various types of pain points...

Check whether there is an error message.

Alert (str );
Check whether it is replaced.


It is estimated that the image name is a Chinese name. Change to English

The JQ plug-in Replaces [face] with 0.png00001.png00002.png.
But it's strange to change face to Chinese...
