Bug #55210 [Bgs]: Certain function names are changed into lowercase....

Edit report at https://bugs.php.net/bug.php?id=55210&edit=1 ID: 55210 User updated by: yurtesen at ispro dot net Reported by: yurtesen at ispro dot net Summary: Certain function names are changed into lowercase.... Status: Bogus Type: Bug Package: Unknown/Other Function Operating System: FreeBSD 8.2-STABLE PHP Version: 5.3.6 Block user comment: N Private report: N New Comment: If the name handling is case-insensitive, how can get_defined_functions() can return same function twice? See array elements 13 and 87. Shouldnt it say that the function was already defined in such case? (because I could define the function twice! see below) Why it accepts getUserID() and also accept getuserid() in one file and in another file which was included from that specific file I can use only getuserid() BUT not getUserID() anymore? As a matter of fact, when this happens, I can redefine getUserID function and that is why it appears twice in the defined functions list.... If there truly was not a problem, any of these shouldnt happen? Interesting enough, only some certain functions seem to be effected seemingly randomly... If you have a clever idea of what I might try to figure out what is happening, please let me know...

Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php PHP is handling function names case-insensitive, for that we need the lower-case version in most places. ------------------------------------------------------------------------ [2011-07-14 17:47:57] yurtesen at ispro dot net Description: ------------ Actually, I am not sure how to track this problem since I couldnt replicate it using a simple test case. I use a software which has a pile of user functions. It loads a common file in each page using require_once() first page loads -> actual page (and both loads the common php file) This common file have function definitions. The problem is that there is a function in the common file which has name getUserID() and it is possible to call this function from the 'first' page, but when one tries to call it from the 'actual' page you get an undefined function error. (yes the require_once for the common page is on the top!). After much research, I found out that somehow PHP changed the function name into lowercase. As a side note, this used to function fine in PHP 5.3.2 and FreeBSD 7.x, I upgraded to FreeBSD 8.x and PHP 5.3.6 (with same configurations) and the problem occured. I can copy/paste the function into the 'actual' file and PHP does not complain about it being redefined (and actually it becomes usable again). Test script: --------------- Below is output of (note that the getUserID is double): print_r(get_defined_functions()); [user] => Array ( [0] => getvariables [1] => isempty [2] => checkpwd [3] => userexists [4] => iscookieset [5] => checkuser [6] => gettotalusers [7] => gettotaladmins [8] => gettotalsupporters [9] => getuserinfo [10] => listmembers [11] => getannouncements [12] => getuserlist [13] => getuserid [14] => getgroupid [15] => getgroupname [16] => groupexists [17] => getpriority [18] => getstatus [19] => issupporter [20] => isadministrator [21] => getsgroup [22] => getgrouplist [23] => getugrouplist [24] => ingroup [25] => getugroup [26] => getmessage [27] => printerror [28] => printsuccess [29] => getrank [30] => getrpriority [31] => getrstatus [32] => gethighestrank [33] => getlowestrank [34] => getsecondstatus [35] => getsecondpriority [36] => getprioritylist [37] => getcategorylist [38] => getstatuslist [39] => createheader [40] => creategroupmenu [41] => createprioritymenu [42] => createstatusmenu [43] => createthememenu [44] => createlanguagemenu [45] => createtimeoffsetmenu [46] => displayticket [47] => createticketinfo [48] => createcategorymenu [49] => createkcategorymenu [50] => createplatformmenu [51] => updatelog [52] => getcurrentlog [53] => deletefromgroups [54] => gettotalnumopentickets [55] => gettotalnumclosedtickets [56] => gettotalnumtickets [57] => validemail [58] => starttable [59] => endtable [60] => sendmail [61] => getemailaddress [62] => showformattedtime [63] => listplatforms [64] => getnumplatforms [65] => listkcategories [66] => getnumkcategories [67] => createkbmenu [68] => makeclickable [69] => setresponse [70] => createviewablebymenu [71] => convertfilesize [72] => getlanguage [73] => createsgroupcheckboxes [74] => createugroupcheckboxes [75] => gettimeoffset [76] => getlastactivetime [77] => stripscripts [78] => getdefaultsupportergroupid [79] => getthemevars [80] => getthemename [81] => listopentickets [82] => getsgrouplist [83] => listbypriority [84] => listbystatus [85] => getnumbergroups [86] => getuserinfo [87] => getuserid [88] => getgroupid [89] => createticketinfo [90] => getdefaultsupportergroupid ) Expected result: ---------------- I expect that function names do not change into lowercase when used inside a file which was loaded by require() And, I tried to test this with a small test case, but PHP worked fine, any hints on how to debug the issue? I didnt re-test installing PHP 5.3.2 yet. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55210&edit=1
