Escape sequences are used for escaping a character during the string parsing. It is also used to represent line breaks, tabs, alerts, and more. The escape sequences are interpolated into strings enclosed by double quotes or heredac syntax.
Escape sequences are started with the escaping character backslash () followed by the character which may be an alphanumeric or a special character. If it is an alphanumeric character, it gives special meaning to represent the line breaks \n, carriage return \r, etc..
If it is a special character, then it will be considered as it is during the string parsing.
Strings in PHP can be specified in four different ways:
Single Quoted, Double Quoted, Heredoc Syntax and nowdac syntax.
The single quoted and double quoted are the most frequently used.
The simplest way to specify a string is to enclose it in single quotes – ‘’. It is the easiest way to define a string. You can use it when you want the string to be exactly as it is written. All the escape sequences like \r or \n, will be output as specified instead of having any special meaning. Single quotes are usually faster in some cases. The special case is that if you to display a literal single-quote, escape it with a backslash() and if you want to display a backslash, you can escape it with another backslash(\).
