问题
I'm using Sublime Text with the Pastels on Dark theme. My language of choice is PHP. How can I get HTML syntax highlighting inside PHP strings & heredoc syntax?
回答1:
Name your heredocs after the language you are using. This will syntax highlight in many text editors, including Sublime Text.
For example:
echo <<<HTML
<!-- put HTML here and it will have syntax highlighting -->
HTML;

Whilst coding outside and then copying in can be a hassle, for people/editors without syntax highlighting in heredoc, an easy workaround is to temporarily add a closing php tag to the heredoc opening tag:
<?php
$myHtmlCode = <<<HTML?>
<h1>I am Highlighted</h1>
<p>Remove the closing php tag above to finish editing</p>
HTML;
?>

Just code outside of php so you can still see the HTML syntax color-coded, and then put that html inside the php once you are done.
