php equivalent to printf("%d\n",__LINE__);

[salmobytes]

In C you can make debug statments that announce the current
line number in the source, with something like:
printf("%d\n",__LINE__);

php (if php.ini is setup that way) often announces
line numbers when catching errors.

How can you do echo the equivalent of C's __LINE__ macro
on non-error but interesting debugging conditions?

If ($checkbook-balance < $100 && $subject == "wife")
echo sys_sourceline(), "<br>"; ....or some such

I forgot to mention this in my previous reply:

Surprise! You can do that with:

<?php
printf("%d\n",__LINE__);
?>
Or you can use the shorter <?php echo __LINE__; ?>
