Since JSON appeared on the web, all web services are offering JSON as their primary data format for data interchanging. The reason JSON is so popular is because it is lightweight and easy for humans to read and write. Today I want to show you how we can use this JSON data in our projects using PHP.
There are various methods we can use to redirect users to different URL. Let’s have a look at codes below with just one goal.
HTML Meta Refresh Tag
Most common way to redirect users to another location is using HTML refresh meta tag, just have this code placed within the <head></head> section of your HTML page :
//Will take you to sanwebe.com
window.location.href = 'http://www.sanwebe.com';
We can use PHP header to redirect user to new URL easily, but remember there must be NO other output before this code, such as echo code which will trigger “headers already sent” error.
Here’s perl code to redirect user to sanwebe.com.
$url = "https://www.sanwebe.com/";
print "Location: $url\n\n";
To redirect users to new location, just drop this header() line in your PHP file. Remember that header() function must be called before any actual output is sent, otherwise you might run into error.
If you are using PHP just drop the following line on top of your script, this will detect whether the request was made using Ajax or not.
