echo variable in double quotes showes a syntax-error in IDE

Question

I use for PHP-coding Aptana Studio.

The following line gives me a syntax-error in Aptana-Studio:

<?php 
   if(isset($GLOBALS['errorSaveProfile'])) echo "<p>$GLOBALS['errorSaveProfile']</p>";
?>

But i don't understand why?

Specifically in the linked question, [this answer `Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE`](http://stackoverflow.com/a/13935532/541091) — Michael Berkowski, Aug 15 '14 at 19:55

Don't use single quotes in double quotes for array keys: echo "<p>$GLOBALS[errorSaveProfile]</p>";

There are different correct ways:

print $_GLOBALS['errorSaveProfile'];
print 'something '.$_GLOBALS['errorSaveProfile'].' something';
print "something {$_GLOBALS['errorSaveProfile']} something";

See http://php.net/manual/en/language.types.string.php#language.types.string.syntax.double and http://php.net/manual/en/language.types.string.php#language.types.string.parsing.simple

A single line or inline if statement is legal. – Sterling Archer Aug 15 '14 at 19:56
You're right. I feel so dumb now. – Branko Sego Aug 15 '14 at 19:58

No worries, I've made mistakes that make something like that look like an award winning speech :P – Sterling Archer Aug 15 '14 at 19:59

That's very ugly code. Concatenation is better here instead of 3 echos on the same line. – Sterling Archer Aug 15 '14 at 19:57
