PHP Browser Specific Codes

PHP Browser Specific Code

The code below can be used to add custom code based on the browser type. Load the page within the popular browsers like Firefox, Chrome, Explorer, Safari and Opera and you will see specific output for each one. The codes can be handy if you need to make a minor css adjustment, redirect, etc.

<?php 

## CHROME
if (strpos($_SERVER['HTTP_USER_AGENT'], 'Chrome') !== false){
echo "This output will only display if the browser is Google Chrome";
}

echo "<br/>";

if (strpos($_SERVER['HTTP_USER_AGENT'], 'Chrome') != false){
echo "This output will only display if the browser is Google Chrome";
}

echo "<br/>";

if (strpos($_SERVER['HTTP_USER_AGENT'], 'Chrome') == true){
echo "This output will only display if the browser is Google Chrome";
}

## FIREFOX
if (strpos($_SERVER['HTTP_USER_AGENT'], 'Firefox') !== false){
echo "This output will only display if the browser is Firefox";
}

echo "<br/>";

if (strpos($_SERVER['HTTP_USER_AGENT'], 'Firefox') != false){
echo "This output will only display if the browser is Firefox";
}

echo "<br/>";

if (strpos($_SERVER['HTTP_USER_AGENT'], 'Firefox') == true){
echo "This output will only display if the browser is Firefox";
}

## EXPLORER
if (strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') !== false){
