How to Properly Create Newline Characters in PHP Strings?

Creating Newline Characters in PHP

When attempting to create newline characters in PHP using single-quoted strings like:

echo $clientid;
echo ' ';
echo $lastname;
echo ' ';
echo '\r\n';

you may encounter issues where the newline is rendered literally in the output.

Solution

The key to resolving this problem lies in understanding the different types of string literals in PHP. Only double-quoted strings interpret the escape sequences r and n as newline characters. Therefore, you should enclose the newline escape sequence in double quotes:

echo $clientid;
echo ' ';
echo $lastname;
echo ' ';
echo "\r\n";

Single-quoted strings, on the other hand, only recognize the escape sequences and '. To create a newline within a single-quoted string, you need to either:

• Concatenate it with a line break generated from a double-quoted string or using the chr() function
• Literally type the newline character into the string using your editor, ensuring that the editor is configured for the desired line break character sequence (e.g., rn)
