Re: global variables

Please use "Reply all" so the post goes to the list. Your code seems fine. The only thing I can think of is that maybe your getting a segfault somewhere which causes php_first_test_init_globals() to be called again?? Though I'm not sure that under a webserver sapi that php module startup process would start all over again after a segfault. Try compiling your extension with --enable-debug and watch for output, check your webservers logs or see if you have any core dumps laying around from it. Maybe some-one else can comment. -Justin ----- Original Message ----- From: "Siewn" <ml@croiset.com> To: "Justin Hannus" <jhannus@visualconceptsinc.com> Sent: Monday, December 06, 2004 12:45 PM Subject: Re: [PECL-DEV] Re: global variables > I'm sorry to disturb you with this problem, I know it's probably simple > but I really tried many ways and I can't find the good one. > > I tried to do as you suggest but it doesn't work. > Your can see ( http://ns3288.ovh.net/~dweis/test_ext.php ), if > you refresh > slowly the variable is well incremented but if you do it fast, it doesn't > work any more and you can guess the variable is initialized in each apache > process. > > If you can just look at my short source code, I would be really thankful. > > http://ns3288.ovh.net/~dweis/first_test.c.txt > http://ns3288.ovh.net/~dweis/php_first_test.h.txt > http://ns3288.ovh.net/~dweis/test_ext.php.txt > > Thanks a lot. > > Tristan > > >>You can do this with a combo of your extension globals struct, which you >>should have defined in your php_ext.h file generated by PECL_Gen or >>ext_skel, and your PHP_MINIT_FUNCTION which is called at module startup. >>Its counterpart is the PHP_MSHUTDOWN_FUNCTION. >> >>On module startup you can build your tree in the PHP_MINIT_FUNCTION and >>store it in your extension globals struct, which can be accessed by other >>functions in your extension.
