How PHP Multiline String With Examples

by

In PHP, the multiline string is very easy they can be written in three different ways, such as with the use of escape sequences, Nowdoc and Heredoc syntax and concatenation assignment operator.

In this article, we will talk about how to Multiline a string in PHP with a detailed explanation as well as example programs that could be helpful to your project development. This topic is a continuation of the previous article, entitled PHP basename Function.

How do I create a multiline string in PHP?

The following list below can be used to create a multiline string:

  • Escape sequences
  • Nowdoc and Heredoc syntax
  • Concatenation assignment operator

PHP Multiline a string using escape sequences

The escape sequences is a way to output special characters and the backslash n (\n) escape sequences can also be used to produce the multiline string.

Example

<?php
      	//declaring multiple lines using the new line escape sequence
      	$name="Glenn\nMagada\nAzuelo";
      	echo $name;
?>

Output

Glenn
Magada
Azuelo

PHP Multiline a string using a Nowdoc and Heredoc syntax

The Heredoc and Nowdoc syntax in PHP can also be used to write and output multi line strings in PHP directly. But still, there are differences in Heredoc and Nowdoc syntax. The Heredoc uses double quoted strings “double” and the parsing of the escape sequences is done inside the Heredoc text. While a Nowdoc uses a single quoted strings ‘single’ and the parsing of the escape sequence is not performed.

Reminder: The Heredoc and Nowdoc syntax delimiters should always be at the beginning of the single line, without any spacing or special characters.

Heredoc example

<?php
 
      $site = "ITSOURCECODE";
      $heredoc1 = <<<HEREA
          Free source code by, $site
          Python projects.
          Java projects
          and any other programming projects
          for free."\n"
      HEREA;
       
      $heredoc2 = <<<HEREB
          Do you have a tutorial, $site?
          Yes, we have
          We provide free source code and tutorial.
          HEREB;
       
      echo $heredoc1;
      echo $heredoc2;
 
?>

Output

    Free source code by, ITSOURCECODE
    Python projects.
    Java projects
    and any other programming projects
    for free."

    "Do you have a tutorial, ITSOURCECODE?
    Yes, we have
    We provide free source code and tutorial.

Nowdoc example

<?php
 
      $site = "ITSOURCECODE";
      $nowdoc1 = <<<HEREA
          Free source code by, $site
          Python projects.
          Java projects
          and any other programming projects
          for free."\n"
      HEREA;
       
      $nowdoc2 = <<<HEREB
          Do you have a tutorial, $site?
          Yes, we have
          We provide free source code and tutorial.
          HEREB;
       
      echo $nowdoc1;
      echo $nowdoc2;
 
?>

Output

 Free source code by, ITSOURCECODE
    Python projects.
    Java projects
    and any other programming projects
    for free."

    "Do you have a tutorial, ITSOURCECODE?
    Yes, we have
    We provide free source code and tutorial.

PHP Multiline a string using concatenation assignment operator

The concatenation assignment operator (=) can also be used to multiline a string. We just need to concatenate the two strings and the PHP_EOL syntax so that we can mark the end line of the string.

Example

<?php
  	$fname="Glenn". PHP_EOL;//PHP_EOL marks end of line so that
  	$mname="Magada". PHP_EOL;//next string get concatenated as new line and closing identifier
  	$lname="Azuelo";
  	$fname.=$mname.=$lname;//concatenating the string into $s1
  	echo $fname;/PHP code for printing final concatenated string
?>

Output

Glenn
Magada
Azuelo
