String in PHP

String in PHP

In PHP string is a sequence of characters i.e. used to store and manipulate text. There are 4 ways to specify string in PHP.

• single quoted
• double quoted
• heredoc syntax
• newdoc syntax (since PHP 5.3)

Single Quoted PHP String

It is simple and easy way to specify string in php. We can create a string in PHP by enclosing text in a single quote.

<?php

$str='Hello php I am single quote String';  
echo $str;

?>

Double Quoted PHP String

In PHP, we can also specify string through enclosing text within double quote

<?php

$str="Hello php I am double quote String";
echo $str;

?>

Note: Now, you can't use double quote directly inside double quoted string.

<?php

$str="Hello "php" I am double quote String";
echo $str;

?>

We can store multiple line text, special characters and escape sequences in a double quoted PHP string.

<?php

$str="Hello \"php\" I am double quote String";
echo $str;

?>

Using double quote String you can also display variable value on webpage

<?php

$num=10;
$str="Number is: $num";
echo $str;

?>
