Re: Compare Values

Hi Frank, What you really want to use is zend_parse_parameters, and it will correctly handle the conversions for you. PHP_FUNCTION(checkval) { char *val; int vallen; if (FAILURE == zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "s", &val, &vallen)) { return; } if (0 == strncmp(val, "1234567890", 10)) { ... first 10 chars are equal .... } } ----- Original Message ----- From: "Frank Liebelt" <frank.liebelt@edico-gmbh.de> To: "PECL DEV Mailinglist" <pecl-dev@lists.php.net> Sent: Saturday, June 26, 2004 6:47 PM Subject: AW: [PECL-DEV] Compare Values Hi > I dont think anyone here is going to laugh, expecially with someone > trying to learn something.

I read the doc but that what i want would'nt work. Here is what i have now: (Don't care about the function name. I will i rename if it worked) PHP_FUNCTION(checkval) { zval **parameter; char *key = NULL; key = "6575736883"; /* argument count is correct, now retrieve arguments */ if((ZEND_NUM_ARGS() != 1) || (zend_get_parameters_ex(1, &parameter) != SUCCESS)) { WRONG_PARAM_COUNT; } convert_to_string_ex(parameter); RETURN_STRING(*parameter,0); } This is for testing only. I send the parameter from the php script like this: echo checkval("65757368837485728368818481837172906871837778837274"); Normally im awaiting a printout of : 65757368837485728368818481837172906871837778837274 But in my Browser i allways see such crypt character : à-22 which is changing after every reload. This isnt my real problem. But this her is: How can i compare the first 10 characters from the given value with the defined key? I dont want other to do my work but a sample function that does my needs would be fine. So i could learn from that.
