In this example, I used the escape sequence \n to add a line break after label and I have used \\ to escape \ character and print it to the browser. This code shows a simple PHP example program to distinguish the behavior of the escape sequences with alphanumeric and non-alphanumeric characters. Without the escaping character (\), the $var PHP variable is parsed to get its value. For example, if we interpolate \$var into a string then it will be taken as $var. If it is a special character, then it will be considered as it is during the string parsing. ![]() If it is an alphanumeric character, it gives special meaning to represent the line breaks \n, carriage return \r and more. ![]() In a previous tutorial, we have seen variable interpolation.Įscape sequences are started with the escaping character backslash (\) followed by the character which may be an alphanumeric or a special character. If a string is within the single quotes or in nowdocs, then the escape sequence will not work to get the expected result. The strreplace () function is used for replacing all the occurences of a word 1 by replacing word 2 in a particular string. The escape sequences are interpolated into strings enclosed by double quotations or heredoc syntax. It is also used for giving special meaning to represent line breaks, tabs, alerts and more.
