<?PHP foreach($_SERVER as $key_name => $key_value) { print $key_name . " = " . $key_value . "<br>"; } ?>
In this coding foreach Condition is used to which Browser the user is to working and
which remote address &IP address all information is to be display.
<?php $referrer = $_SERVER['HTTP_REFERER']; $browser = $_SERVER['HTTP_USER_AGENT']; $ipAddress = $_SERVER['REMOTE_ADDR']; print "Referrer = " . $referrer . "<BR>"; print "Browser = " . $browser . "<BR>"; print "IP Adress = " . $ipAddress; ?>
In the above coding is usefull to find out which browser the user is to be working
on&which ip address&which referrer (i.ein which domin&folder the user is working).
Try this Script.
<?PHP //$space = "creatersite"; $space = trim(" hello ");//trim() is to remove space $letCount = strlen($space); print $letCount; ?>
In this Coding why we have to use trim function to remove the space between the letters
and characters $space = trim(" hello ");
We didn't use the trim function we can see that there is extra space before and after
the text take and count the length.$space = "creatersite";
