tags - What is the correct way to comment out a PHP variable being echoed using shorthand notation? -

i have started using php shorthand <?= ?> tags echo variables etc in php scripts. find if want comment out variable, e.g. <?= //$myvariable; ?> syntax error.

is safe this: <?//= $myvariable; ?>

many thanks!

the short tag

<?= ... ?>

is translated into

<?php echo ...; ?>

so comment out, have set ... shows empty. here's shortest can come with:

<?= false && ... ?>

this works because echo false echoes nothing.

there's no documentation supporting it, might old compatibility hack, next seem work:

<?//= ... ?>

and

<?/*= ... */?>

since they're undocumented, wouldn't depend on them important, utilize them if you're temporarily commenting out while debugging.
