	WTF...
	Why does my server not like: `if (isset($_POST['url'])) { #clean URL print $_POST['url']; /* $out = escapeshellarg("addblog-test.pl $url"); print $out; / } if ($errors){ print "$errors "; }` (it gives me an error: Parse error: syntax error, unexpected '}' in /home/uvemympn/public_html/dev/addblog.php on line 16, which line 16 is the last line.) Yet it's perfectly fine if I take out the comments? `if (isset($_POST['url'])) { #clean URL print $_POST['url']; } if ($errors){ print "$errors "; }` I don't get it. I really don't. I even tried different ways of commenting... # and // both... Tags:* php

eek... It looks like php but it hurts my eyes!

Simple guidelines I would use:
- use // and /* comments not # (stylistic choice on my part
- don't make strings span newlines unless you have to.
- don't embed variables in strings "start $out end" vs "start ".$start." end", it usually works but sometimes it doesn't.
- I like to use echo instead of print, but that's just because I like being reminded I'm doing php and not C
- use proper indentation always, just for shits and giggles

In any case I copy pasted the corrupt code from my browser view of your page and it processed happily on my server.

-# is comments in perl (// and /* fail, I believe), and since that's the last language I'd been coding in... :: shrugs::
-Embedded variables in strings sometimes doesn't work? In perl, "out=$out" will cause the value of $out to be uh.. embedded, while 'out=$out' will return literally "out=$out". I've been presuming PHP is the same.
-Hm, I believe echo vs. print is just a stylistic choice. I think one might be slightly faster, although I may be mistaken.
-Eh, yeah, I do use proper indentation (4 spaces per tab, tabbing everything inside curly brackets. And I follow (Java?) suggestions of double-tabbing a hard-wrapped line of code. I just didn't bother fixing the spaces when I copied it over to livejournal - despite the fact that it would be just a s/ / /g replacement.

Huh. Wonder if it's a problem with totalchoicehosting's server... Buggers.

According to Macromedia Dreamweaver, # // and /* are valid php comments. As for php variables in strings it will embed variables values if it notices the variable in the string... however it has trouble if you don't have spaces around the variable name and so occasionally it misses the variable and just embeds the dollar sign name.... unless you explicitly use the concatenate operator (.)
Like I said, arbitrary choice on echo. And I figured the indentation self died... next time copy paste the code into a <pre></pre> block. I do that most of the time for code. I personally like tab-character indentation because then one keypress = 1 unit of operation.

The Wizard's Oath, species-nonspecific recension

In Life's name, and for Life's sake, I assert that I will employ the Art which is its gift in Life's service alone. I will guard growth and ease pain. I will fight to preserve what grows and lives well in its own way; Nor will I change any creature unless its growth and Life, or that of the system of which it is part, are threatened. To these ends, in the practice of my Art, I will ever put aside fear for courage, and death for Life, when it is fitting to do so- looking always toward the Heart of Time, where all our sundered times are one, and all our myriad worlds lie whole, in that from which they proceeded...
