php - How to create mentions for names like "@myname" using javascript? -


I am planning to create a web app and I have a question about how to create a Facebook or Twitter name like "@ Myname "is named

Find them in a string with this regex .... < / P> 

  $ Str = 'yo @bob, what's up? I have a new email, tell tom@bob.com, @Joyon, @ Alex ;; Preg_match_all ('/ \ s @ (? P & lt; ment & gt; \ w +?) \ B /', $ str, $ is mentioned); Var_dump ($ ment);   
 output  
  array (3) {[0] = & gt; Array (3) {[0] = & gt; String (5) "@bob" [1] = & gt; String (6) "@John" [2] = & gt; String (6) "@ black"} ["ment"] = & gt; Array (3) {[0] = & gt; String (3) "Bob" [1] = & gt; String (4) "John" [2] = & gt; String (4) "Alex"} [1] = & gt; Array (3) {[0] = & gt; String (3) "Bob" [1] = & gt; String (4) "John" [2] = & gt; String (4) "Alex"}}   
 Of course, you can recognize them in real-time JavaScript in a string, just change a regex to javascript.  
 Then, you will see your database based on the name you tagged, and then do what you need to do!  
 You can deduct requests by restricting your regex as a valid username, e.g.  / \ w {6,} / .
