RE: [PHP] Building Dynamic Value list using ohp

The following works : error_reporting(E_ALL); $arr = array ('a' => 'apple','b' => 'banana'); print "I'd like an $arr[a] today, and a {$arr['b']} too"; I used to assume "foo $arr[a]" would give a Warning but it doesn't as the constant 'a' isn't looked for in the string, but : print $arr[a]; // apple and a Warning // Warning: Use of undefined constant a - assumed 'a' define('a','b'); // define a as a constant with value of b print $arr[a]; // banana and no Warning print $arr['a']; // apple and no Warning (quotes are good) Numerical arrays work fine in a string, such as "foo $array[0]". Maxim is referring to "foo $arr['a']" creating a parse error, one that looks like : Parse error: parse error, expecting T_STRING' or T_VARIABLE' or `T_NUM_STRING' in /www/htdocs/test.php on line 4 As it does. The Warnings shown above refer to the E_NOTICE level. Have fun and yes, this is a digression and off-topic :) Regards, Philip Olson > 1. this: > print("<option value=\"$row[0]\">$row[0]</option>"); > should be this: > print("<option value=\"{$row[0]}\">{$row[0]}</option>"); > or like this: > echo '<option > value="'.$row[0].'">'.$row[0].'</option>'); > > The reason for it is that within double quote you can parse for 'simple' > variables only (es: $var, not $var[]).
