Description:
------------
Parse error: syntax error, unexpected "(T_ENCAPSED_AND_WHITESPACE), expecting identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING).
Apparently, the parser cannot dereference $Apt['Color']. May be linked to bug 23022. But why the <unexpected ">?

Test script:
---------------
<?php
#No error, using intermediate var $Colo:
	forEach ($GLOBALS['Aps'] as $GLOBALS['X'] => $Apt){
		$Colo=$Apt['Color'];
		echo "<div class='row' style=\"background-color: $Colo\">";
		echo '</div>';}

#Parse error: syntax error, unexpected '' (T_ENCAPSED_AND_WHITESPACE), expecting identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING) in C:\Apache24\htdocs\GoodBadB.php on line 10:
	forEach ($GLOBALS['Aps'] as $GLOBALS['X'] => $Apt){
		echo "<div class='row' style=\"background-color: $Apt['Color']\">";
#Apparently, the parser cannot dereference $Apt['Color']. May be linked to bug 23022. But why the <unexpected ">?
		echo '</div>';}
?>

No.  The parser won't just accept this syntax.  See the manual[1]
on how to use array indexes in strings.

IMHO, this is not a bug.

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

Correct, this is not a bug. In string interpolation use either "... $array[key] ..." or "... {$array['key']} ...".
