\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

Conclusion 0c6dc11e160d3b678d68754cc175188a 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 0c6dc11e160d3b678d68754cc175188a, although the web page displays a line wrapping result, when viewing the web page source code label 0c6dc11e160d3b678d68754cc175188a 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
