Difference between print and echo in PHP
I am not going to be too verbose on this one because there is no reason to.
Both echo and print do the same thing with the exception that:
1. "echo" seems to be faster
2. "print" does return true or false and echo does not.
Other than that it is just a matter of preference.

Convert String from UTF- to ISO-8859-1 in PHP
If your html looks like “ycsoftware †categories“, you will need to use the ICONV function to convert the string to something that humans can read.
$str = iconv("UTF-8", "ISO-8859-1//TRANSLIT", $str);
Your result should look like:
ycsoftware - categories
Change remote desktop (RDP) listening port
If you find yourself unable to access your remote PC because a firewall is blocking port 3389, you may want to try one the following options listed below:
First Option
create a NAT route on your firewall, to route all traffic from one port to another. let's say you choose port 80 as your entry port; the firewall should not block this port.
1. Open port 80 on your router 2. Create the NAT route to port 3389 (see image below) 3. On your RDP client access your remote pc using "youridaddress:80"
Second Option
Use this microsoft tool to change the RDP port from 3389 to something else (run it on the computer you are trying to access remotely).

Meaning of Curly Braces in PHP
What is the meaning of curly braces in PHP?
In PHP curly braces are used to explicitly indicate the end of a string.
for example let’s say you have this:
$computer = ‘computer’;
if i write
echo “There are 10 $computers in the room”;
The parser will tell that it does not recognize $computers.
Notice: Undefined variable …
however the parser will be very happy with the following:
echo "There are 10 {$computer}s in the room";
