[SOLVED] PHP Browser Check

[mattal999]

Hi,

 

I have this:

 

<?php

$browser=strtolower($_SERVER['HTTP_USER_AGENT']);
if(strpos($browser, 'msie')) {
?>
<link rel="stylesheet" type="text/css" href="css/style.css" />
<?php
} else if(strpos($browser, 'chrome')) {
?>
<link rel="stylesheet" type="text/css" href="css/stylechrome.css" />
<?php
} else if(strpos($browser, 'firefox')) {
?>
<link rel="stylesheet" type="text/css" href="css/styleff.css" />
<?php
} else if(strpos($browser, 'opera')) {
?>
<link rel="stylesheet" type="text/css" href="css/styleopera.css" />
<?php
} else {
?>
<link rel="stylesheet" type="text/css" href="css/styleff.css" />
<?php
}

?>

 

And i have checked Opera's output of $browser, which is: opera/9.51 (windows nt 5.1; u; en)

 

However, it doesn't detect the word opera in that phrase!!! Help!

Bump

is it case sensitive?

Try stripos().

[mattal999]

1: I used strtolower -.-

 

2: I don't have stripos...

 

Any other ideas?

You're using PHP4...?  Why?

[hamza]

yeah it is working fine with the browser's

there must be a little problem i dont have opera

so its quite difficult to try thsi problem

 

but change anyother php funtion

other then this strpos because

function in php are not 100% successfully

running every time there are many problems

in fucntion some time it works sometimes not,.

 

so i suggest you to change or use any other one

 

thanks and regards

...What?

 

Also, your problem is that you're not using strpos() correctly.  strpos() returns the position of the found string, correct?  If it finds the string at position 0 in your big string, it returns 0.  If used as you have it set up, this evaluates to FALSE and then doesn't activate the if.  You need to do:

 

if (strpos($browser, 'opera') !== false) {

 

}

 

That should be done for ALL of them, and any other time you use strpos, btw.
