PHP Concatinating Strings

In PHP, concatination is the joining of strings. The easiest way to explain this process is through the following examples.With concatinatiion, two variables can be joined with a period inserted between them.

Example 1

$var1=”My name is”;
$var2=”John”;

echo $var1.$var2;
#Ouput is My name isJohn.
 

Example 2

$var1=”My name is”;
$var2=” “; //space
$var3=”John”;

echo $var1.$var2;
#Ouput is My name is John.

Example 3

$var1=”My name is”;
$var2=”John”;

echo $var1.” “.$var2;
#Ouput is My name is John.

Notes:
With php, all text between quotes can be ended with a period. In example 3, a space was created after $var1. We simply used quotes to make a space.

Below, is the same as example 3 with the exception of using single quotes.

$var1=”My name is”;
$var2=”John”;

echo $var1.’ ‘.$var2;
#Ouput is: My name is John.
