Constants in double-quoted strings

Hello, What is the chance of support for constants in double-quoted strings in PHP 5.3 or PHP 6.0? This is something I have wanted for some time now. Use cases: Writing an SQL query that makes use of a status field <?php define ('STATUS_ACTIVE', 1); define ('NUM_PER_PAGE', 25); $q = "SELECT ID, Name FROM Projects WHERE StatusID = " . STATUS_ACTIVE . " LIMIT " . NUM_PER_PAGE . " OFFSET {$offset}"; $res = mysql_query ($q); ?> Syntax suggestions: Constants would need to be contained within curly braces. e.g. "SELECT ID, Name FROM Projects WHERE StatusID = {STATUS_ACTIVE} LIMIT {NUM_PER_PAGE} OFFSET {$offset}" The syntax would therefore be: '{', one or more of [-_a-zA-Z0-9], '}' If not constant is found, the string should be inserted directly. If that causes too much parsing issues, perhaps a symbol should be placed before or after the opening brace. e.g. "SELECT ID, Name FROM Projects WHERE StatusID = {#STATUS_ACTIVE} LIMIT #{NUM_PER_PAGE} OFFSET {$offset}" Regards, Josh
