There are two string operators. The first is the concatenation operator (‘.‘), which returns the concatenation of its right and left arguments. The second is the concatenating assignment operator (‘.=‘), which appends the argument on the right side to the argument on the left side.
Examples :
Input : string1: Hello
string2 : World!
Output : HelloWorld!
Input : string1: geeksfor
string2: geeks
Output : geeksforgeeks
Code #1:
<?php // First String $a = 'Hello'; // Second String $b = 'World!'; // Concatenation Of String $c = $a.$b; // print Concatenate String echo " $c
"; ?> |
Output :
HelloWorld!
Code #2 :
<?php // First String $fname = 'John'; // Second String $lname = 'Carter!'; // Concatenation Of String $c = $fname." ".$lname; // print Concatenate String echo " $c
"; ?> |
Output :
John Carter!
Code #3 :
<?php // First String $a = 'Hello'; // now $a contains "HelloWorld!" $a. = "World!"; // Print The String $a echo " $a
"; ?> |
Output :
HelloWorld!
