How will you concatenate two strings in PHP?

PHP | Combine two strings

There are several ways to concatenate two strings in PHP.

Use the concatenation operator [.] and [.=]

There are two string operators which is use for concatenation.

[.]    :  Concatenation operator | Used to combine two string values to create a new string.
[.=]  : Concatenation assignment operator | Appends the argument on the right side to the argument on the left side.

 

Concatenation operator

 <?php

$str1="Hello World! ";

$str2="Welcome to StudyZone4U.com";

echo $str1 . $str2;

// output
//This will produce following result −
//Hello World! Welcome to StudyZone4U.com

?>

 


 

Concatenation assignment operator

 <?php

$str1 = "Hello World! ";

// Use og concatenation assignment operator
$str2 .= "Welcome to StudyZone4U.com";

echo $str2;

// Output:
// Hello World! Welcome to StudyZone4U.com

?>

 


 

Double quotes strings

PHP variables also work inside double quotes. So if you place the php variable inside double quotes and just put a space between both the PHP variable will work the same

 <?php

$str1 = "Hello World!";

$str2 = "Welcome to StudyZone4U.com";

// Use of Double quotes
// The curly braces have used here to make the things clear.

echo "{$str1} {$str2}";

// Output:
// Hello World! Welcome to StudyZone4U.com

?>

In the above example you can directly use the  PHP variable without curly braces. The curly braces have used in the above example to make the things clear.

 <?php

// without curly braces

echo "$str1 $str2";

// Output:
// Hello World! Welcome to StudyZone4U.com

?>

 

 


 

Use a cmmma "," with echo() statement

This used only when you what to print the thing directly on the webpage. The echo statement can take multiple variables as a list by using comma to seperate the variables.

So, let's see who its work

 <?php

$str1 = "Hello World!";

$str2 = "Welcome to StudyZone4U.com";


echo $str1, ' ', $str2;

// Output:
// Hello World! Welcome to StudyZone4U.com

?>
