30-day PHP learning record (line break)

PHP newline character

I originally thought that using double quotes could escape \n or
Perform a newline operation and find

\nUsage

The following code

<?php
    echo "nocs\n";    echo "you";?>

Online editing The output result of the processor shows

nocs
you

The output result of the webpage shows

nocs you

It can be seen that the webpage display does not have a line break effect, it is only displayed as a space
Conclusion:\nLine breaks are only applicable to command line execution

##
Usage

The following code

<?php
    echo "nocs<br>";    echo "you";?>

Online editor Display results

nocs<br>you

Web page display results

nocs
you

You can find that the web page display
achieves the line wrapping effect

Conclusion
Web page display line breaks can be realized

Notes

Found a phenomenon when using double quotes to escape the \n character. The web page display does not realize line wrapping, but when viewing the web page source code, the line wrapping effect is achieved

When using double quotes to escape
, although the web page displays a line wrapping result, when viewing the web page source code label
is still displayed Come out
This means that the result of viewing the source code of the web page is consistent with the result displayed by compiling PHP from the command line
