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!
