hi! that´s my first post in this forum. And hopefully not my last one. Iam currently writing my first php extension and got into a problem. My goal is a function that takes the return value of a fsockopen call as argument. I want to use this open connection to get the SSL-Certificate of this peer. Iam using most of the code of the function: php_stream_sock_ssl_activate_with_method (can be found in main/network.c) the error i get is: [code]if (!php_stream_is(stream, PHP_STREAM_IS_SOCKET)) { php_error_docref(NULL TSRMLS_CC, E_WARNING, "php_stream_sock_ssl_activate_with_method: stream is not a network stream"); return FAILURE; }[/code] this code is copied and pasted from the method in the php src. So the stream is not a network stream. Now i will show you my ssl_get_cert function: [code]#define PHP_STREAM_TO_ZVAL(stream, arg) \ php_stream_from_zval_no_verify(stream, arg); \ if (stream == NULL) { \ RETURN_FALSE; \ } PHP_FUNCTION(ssl_get_cert) { zval **arg1; php_stream *stream = NULL; int x509; if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "z", &arg1) == FAILURE) return; PHP_STREAM_TO_ZVAL(stream, &arg1); Z_TYPE_P(return_value) = IS_RESOURCE; php_get_ssl_cer(stream, Z_LVAL_P(return_value) TSRMLS_CC); } [/code] the code in my .php file would be something like [code]$fp = fsockopen ("www.acrm.de", 443,$errno, $errstr, 3); if (!$fp) { print("No connection"); echo "$errstr ($errno)<br />\n"; } else { $testcert = ssl_get_cert($fp); ... [/code] but $fp is not a network stream... if i comment the part were the error gets thrown it doesn´t work either so i think i need a network stream... I hope you can help me out guys cause iam stuck. thanks for every suggestion/help
