Question: Hello I want to get user from an email address,

eg: ***sajid@webspot.com*** then output must be ***sajid***

for this i use below mentioned code 

```
$user = strstr($email, '@', true);

```

but an warning occur 

**Warning: Wrong parameter count for strstr() in /var/www/DataTable/dialog.php on line 3**

& in php manul it is clearly define that the 3rd argument true is only valid for ***PHP 5.3.0***

So is there any string function which could solve my problem?

Answer: 
```
$user = substr($email, 0, strpos($email, '@'));

```
