Question

If you use phpinfo() in your page, you will notice it will change the title of your page? And even if you give the title of your page to be different it will not change. How is this done?

Answer 1

Chrome, Firefox and internet explorer is practicing FIFO.

So, do this

<title>my title</title>
<?phpinfo() ?>

is my title being set as browser page title

<?phpinfo() ?>
<title>my title</title>

Then above will set page title to phpinfo()
