Re: [PHP4BETA] Difference in parsing "{" inside control loops

Hello, I am trying imp with php4.0b2, and I found out its not working because of the following lines: while(!is_object($structure) || !imap_ping($mbox)) {

    $mbox = imap_open("{$server:$port}$mailbox", $user, $pass);
    $structure = @imap_fetchstructure($mbox, imap_msgno($mbox, $index));

} To make it working I had to add a backslash before "{" in the second line:

    $mbox = imap_open("\{$server:$port}$mailbox", $user, $pass);

Is it expected behaviour? The braces are quoted and I think should not affect the control loop. Looks like a bug to me. It did work for php3.

It's no bug - PHP 4.0 supports full variable evaluation inside quoted strings using "{$foo...}" notation. It is an incompatibility with 3.0, and the solution is to escape { or $ as you did.
