I've been battling with quotes encoding when outputting javascript with php.
It can't be unique, so I'm hoping someone has a working solution they're
willing to share.
The following works perfectly as long as there aren't any single quotes in
the link text:
echo span onclick=\insertLink('$sUrl','$sTitle')\
class='linkSel'$sTitle/span;
if $sTitle has the valueWhat's newit outputs:
span onclick=insertLink('article/whats-new.html','What#039;s
new') class='linkSel'What#039;s new/span
It displays fine, but javascript complains with:
Expected ')' linkmanager.php Line:525 Char:63
So I fix this by swapping the double and single quotes around:
echo span onclick='insertLink(\$sUrl\,\$sTitle\)'
class='linkSel'$sTitle/span;
Now for that specific link it outputs:
span onclick='insertLink(article/whats-new.html,What#039;s
new)' class='linkSel'What#039;s new/span
And javascript is happy.
But elsewhere there's a link Fred Buster Cox and it outputs:
span onclick='insertLink(article/fred-buster-cox.html,Fred
quot;Busterquot; Cox)' class='linkSel'Fred quot;Busterquot; Cox/span
Again it displays fine, but javascript complains with:
Expected ')' linkmanager.php Line:743 Char:77
So it looks like I can't have links that include single quotes and double
quotes, only one or the other.
One work-around I thought of was to convert any link texts that included
double quotes into single quotes when the content is posted, and it would
then be displayed with single quotes even though the user entered double
quotes. It's far from ideal but it would work, though I can think of a few
situations where it would be quite confusing to the reader. Are there any
other solutions that would allow both types of quotes without any
conversions?
Cheers

You aren't escaping the quotes correctly when they go into your output. You're
escaping them for html not javascript. Javascript (like php) escapes single
quotes inside a single quote string with a back slash.

I'm not sure what would have saved bacon in the above case. I don't see how
your example would work. I think it contained a typo.
In what I think you were trying to demonstrate, I would just pass $x by
reference ($x) -- or -- return $x by value. I would not have used a global,
In any event, I seldom use globals anyway. This was more an academic discussion.

You are understanding it correctly, the only thing that's missing
is the population. The variables are defined (set), but not all are
populated. $GLOBALS is a superglobal, you're right; globals set from
userland scripts are not superglobals, but do wind up in the $GLOBALS
array. Thus, all superglobals are globals, but not all globals are
superglobals.
So, it's a question of population timing -- I see.
Additionally, I like the term userland -- I will use it in class. :-)
What would be the opposite term, serverland?
Thanks,
tedd

I would indeed mark it as bad practice using them. I only use them for
debugging purposes. When developing something, you might end up
needing some global variable temporary, and you don't want to pass it
through a few dozen functions before reaching the one where you need
it.

If you're being academic about it please remember that the way PHP defines
globals is different to most other languages.
PHP: A variable defined at the top-level scope.
World: A variable that is visible at every scope.
This is an important difference if you ever move from PHP to another language.
It ultimately also means that only the superglobals are true globals.
The $GLOBALS superglobal contains all variables defined at the top-level scope,
including $GLOBALS, so $GLOBALS['GLOBALS']['GLOBALS']['GLOBALS']['_SERVER'] is
a perfectly valid, if daft, way of accessing $_SERVER.

That was my initial statement in this thread.
After 47 years of programming, I think I'm beginning to get the idea. :-)
As I've said for many years I've learned something new every day of my life --
and I'm getting damned tried of it.
