Do action based on user agent

If user_agent does not contain any of the words from an array of words I define, then a certain action is taken.

Please help me code this block in php.
Code should be as small as possible and streamlined.

Thanks

 

php.net/in_array

 

aha! that I know...I need a complete block of php code or function.

Say I define array $a = 'opera','firefox','bot'
$_SERVER['HTTP_USER_AGENT'] - I get the browser or robot's user_agent string.

Now, if any of the words in $a does not occur in user_agent string, I do something.
Remember user_agent returns a complex phrase with numbers, symbols and letters.

 

$array = array('MSIE 6', 'Opera/6', 'Mozilla/6', 'Googlebot');

foreach($array as $key => $value) {

if( in_array( !strstr($_SERVER['HTTP_USER_AGENT'], $value), $array )  ) {


// replace this with your actions
echo "Key: $key => Value: $value"; 

   }

}

PHP:

...does the job.

 

wing's code will do the job indeed.
What you might also find interesting, is the get_browser() function; note that not all hosts support this! However, if your host supports it, this can do the job very well too

 

I get the following output :

What need is like this (the code is incorrect, kindly help me correct this and test run it)

<?php
$array = array('firefox','bot','slurp','inktomi');
$ua_flag=1; //assume non specified user agent

foreach($array as $key => $value)
{
	if ( in_array( !stristr($_SERVER['HTTP_USER_AGENT'], $value), $array )  )
	{
		$ua_flag=0; //specified user agent found
		break;
	}
}
echo $_SERVER['HTTP_USER_AGENT'];
if ($ua_flag==1) echo "\nspecified agents not detected";
?>

PHP:

 

	$ua_flag="";

	$array = array('firefox','bot','slurp','inktomi');
	foreach($array as $key => $value) {

	if( in_array( !strstr($_SERVER['HTTP_USER_AGENT'], $value), $array )  ) {
	
	$ua_flag = 0; //--> No value was found, set $ua_flag to 0

 	}
 	
 	else {

 	$ua_flag = 1; //--> A value was found, set $ua_flag to 1


	}

 }

PHP:

 

Same thing wrapped as a function. Returns 1 (true), if value is found.

$myarray = array('firefox','bot','slurp','inktomi');
	
	function getstuff() {
		global $myarray;
	
		foreach($myarray as $key => $value) {

		if( in_array( !strstr($_SERVER['HTTP_USER_AGENT'], $value), $myarray )  ) {
	
		return false;
	
		}

		else
	

		{
			
			
	   return true;
	 
	}

  }

}
