Escape sequences in strings in PHP

Introduction

Escape sequences let you put special characters inside strings that are hard to type directly, like new lines or tabs.

When you want to add a new line inside a string to make output easier to read.

When you need to include quotes inside a string without ending it early.

When you want to add a tab space inside a string for formatting.

When you want to include a backslash character itself inside a string.

When you want to add special characters like carriage return or alert sounds.

Syntax

PHP

"\n", "\t", "\\", "\"", "\'"

Escape sequences start with a backslash (\) followed by a character.

Use double quotes for strings with escape sequences to work properly in PHP.

Examples

Adds a new line between Hello and World.

PHP

$text = "Hello\nWorld!";
echo $text;

Includes double quotes inside the string.

PHP

$quote = "She said, \"Hi!\"";
echo $quote;

Shows how to include backslashes in a file path.

PHP

$path = "C:\\Program Files\\";
echo $path;

Adds a tab space between two words.

PHP

$tabbed = "Column1\tColumn2";
echo $tabbed;

Sample Program

This program shows different escape sequences: new line, quotes, backslashes, and tab.

PHP

<?php
$text = "Line1\nLine2";
echo $text . "\n";

$quote = "He said, \"Hello!\"";
echo $quote . "\n";

$path = "C:\\Windows\\System32";
echo $path . "\n";

$tab = "Name\tAge";
echo $tab . "\n";
?>

Important Notes

Single quoted strings in PHP do not interpret most escape sequences except \' and \\.

Always use double quotes if you want escape sequences like \n or \t to work.

Remember to double backslashes when you want to show a single backslash.

Summary

Escape sequences let you add special characters inside strings.

Use a backslash (\) before a character to escape it.

Double quotes are needed in PHP strings to recognize escape sequences.
