php Function Nl2BR - How to Transform Newline Escape Sequences Into Br Tags

When writing a web program, it is common to add line breaks to make the text more readable on a browser. The easiest way to do this is by using the HTML tag br>. However, sometimes it might be required to use other characters in order to create a new line. This is when php function nl2br comes in handy.

The nl2br() function is an inbuilt Php function which converts newline escape sequences in the string to br> tags. The function is usually used when displaying user-submitted data on a webpage or to format text in plain text fields in web applications. The function also helps with escaping special characters in the string and formatting user input so that it is not vulnerable to cross-site scripting attacks.

It takes two arguments and returns the converted string. The first argument is the string which is to be transformed and the second one is an optional parameter for determining whether or not the function will use XHTML-compliant line breaks. The default value for this parameter is set to true.

The nl2br() function will transform all the newline escape sequences in the string into br> tags. It will also replace all the special characters with <special>. It is an extremely useful function which can be incorporated in your code to make the output more readable. This will help in increasing the readability of your web program and improve its usability. It is especially useful when displaying text input submitted by users or when creating plain text emails.
