Req #47331 [Opn->Sus]: use a function's default arguments but change one of the end ones in the list

Edit report at https://bugs.php.net/bug.php?id=47331&edit=1 ID: 47331 Updated by: cmb@php.net Reported by: daevid at daevid dot com Summary: use a function's default arguments but change one of the end ones in the list -Status: Open +Status: Suspended Type: Feature/Change Request -Package: Feature/Change Request +Package: *General Issues PHP Version: 5.2.9RC1 Block user comment: N Private report: N New Comment: This language change would require the RFC process[1], and as such I'm suspending this ticket for the time being. Note that there is already a very similar RFC in discussion phase[2]. Note also that your suggestion to use = in the function call would cause an ambiguity, i.e. a BC break at least.

The concept is simple, just specify which parameters in the function call you want to change and leave the others as their default. So given a function that takes seven parameters, I want to change one (or more) of them and leave the other defaults alone without specifically re-defaulting each value (which assumes I even know what each default value is to begin with) Bug #2285 is similar, but passing an array is a hack and not acceptable. It will not help in an IDE setting to see foo(array) and not know which key/values the hash expects. Bug #20544 is also close, but I don't agree with using "->" or "=>" either. it should just be "=" as illustrated below. Bug #24153 is also similar, but using "," as place holders seems a little hacky too and difficult to read. Plus who wants to count empty place holders to figure out which parameter is being set? Reproduce code: --------------- function SQL_QUERY($sql, $parameters = null, $showSQL = false, $showErrors = true, $execute = true, $noHTML = false, $profile = 0) { var_dump($sql, $parameters, $showSQL, $showErrors, $execute, $noHTML, $profile); } SQL_QUERY('SELECT * FROM foo WHERE bar = ?', array('beep'), $execute=false); The above function call doesn't error out on me, it just seems it doesn't do anything either :-\ Expected result: ---------------- string(31) "SELECT * FROM foo WHERE bar = ?" array(1) { [0]=> string(4) "beep" } bool(false) bool(true) bool(true) <-- I would have expected this one to be bool(false) bool(false) int(0) Actual result: -------------- So it seems I have to do this verboseness (AND know what the default values are to begin with too): SQL_QUERY('SELECT * FROM foo WHERE bar = ?', array('beep'), false, true, false, false); Just to change one default parameter near the end?!? :-( ------------------------------- P.S. this PHP bug report form made me choose a PHP version to submit this, even though I picked "irrelevant" I had to then choose 5.2.9rc1 just to submit :-\ ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=47331&edit=1
