从字符串中获取电子邮件ID

Question

I have array containing strings in format like:

[e-mail] Entry ID: 12321
[e-mail] Entry ID: 12322 Entry ID: 12323
[e-mail] Entry ID: 12324 Entry ID: 12325 Entry ID: 12326
[e-mail] Entry ID: 12327 Entry ID: 12328
[e-mail] Entry ID: 12329 Entry ID: 123210

and I want to fetch only email address from each string & push into an array.

I tried http://www.webdeveloper.com/forum/showthread.php?200875-extract-email-from-string-text-%28patterns%29

and many others from Stackoverflow but browser shows blank screen on echo/print_r

Answer 1

if the string always starts with a email adress. You can work like this:

foreach($emailArray as $value){ 
  $email = explode(" ",$value)[0];
}
