Few days before, I was sending curl execution request for posting data, But I was unable to get the curl response and even error also. I tried Google and found some trips to check the error occurring on executing curl request.
Steps are as follows :
1. Place this code before executing curl (curl_exe) :
0 1 | curl_setopt($chSt, CURLOPT_FAILONERROR, true); |
$chSt- cURL handle returned by curl_init()
2. If we want to know the Http status code then place this statement after curl_exec :
0 1 | $httpstatus = curl_getinfo($chSt, CURLINFO_HTTP_CODE); |
3. If we want to get the Error No. then use this statement after curl_exec :
0 1 | $curl_errorno = curl_errno($chSt); |
4. If we want to get Error message, use curl_error() :
0 1 2 3 4 | if(curl_exec($chSt) === false) { echo 'Curl error: ' . curl_error($chSt); } |
This function Returns the error message or ” (the empty string) if no error occurred.
but we need to set following option before curl_exec() :
0 1 | curl_setopt($chSt, CURLOPT_RETURNTRANSFER, true); |
Curl errors are as follows :
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 | <?php $error_codes=array( [1] => 'CURLE_UNSUPPORTED_PROTOCOL', [2] => 'CURLE_FAILED_INIT', [3] => 'CURLE_URL_MALFORMAT', [4] => 'CURLE_URL_MALFORMAT_USER', [5] => 'CURLE_COULDNT_RESOLVE_PROXY', [6] => 'CURLE_COULDNT_RESOLVE_HOST', [7] => 'CURLE_COULDNT_CONNECT', [8] => 'CURLE_FTP_WEIRD_SERVER_REPLY', [9] => 'CURLE_REMOTE_ACCESS_DENIED', [11] => 'CURLE_FTP_WEIRD_PASS_REPLY', [13] => 'CURLE_FTP_WEIRD_PASV_REPLY', [14]=>'CURLE_FTP_WEIRD_227_FORMAT', [15] => 'CURLE_FTP_CANT_GET_HOST', [17] => 'CURLE_FTP_COULDNT_SET_TYPE', [18] => 'CURLE_PARTIAL_FILE', [19] => 'CURLE_FTP_COULDNT_RETR_FILE', [21] => 'CURLE_QUOTE_ERROR', [22] => 'CURLE_HTTP_RETURNED_ERROR', [23] => 'CURLE_WRITE_ERROR', [25] => 'CURLE_UPLOAD_FAILED', [26] => 'CURLE_READ_ERROR', [27] => 'CURLE_OUT_OF_MEMORY', [28] => 'CURLE_OPERATION_TIMEDOUT', [30] => 'CURLE_FTP_PORT_FAILED', [31] => 'CURLE_FTP_COULDNT_USE_REST', [33] => 'CURLE_RANGE_ERROR', [34] => 'CURLE_HTTP_POST_ERROR', [35] => 'CURLE_SSL_CONNECT_ERROR', [36] => 'CURLE_BAD_DOWNLOAD_RESUME', [37] => 'CURLE_FILE_COULDNT_READ_FILE', [38] => 'CURLE_LDAP_CANNOT_BIND', [39] => 'CURLE_LDAP_SEARCH_FAILED', [41] => 'CURLE_FUNCTION_NOT_FOUND', [42] => 'CURLE_ABORTED_BY_CALLBACK', [43] => 'CURLE_BAD_FUNCTION_ARGUMENT', [45] => 'CURLE_INTERFACE_FAILED', [47] => 'CURLE_TOO_MANY_REDIRECTS', [48] => 'CURLE_UNKNOWN_TELNET_OPTION', [49] => 'CURLE_TELNET_OPTION_SYNTAX', [51] => 'CURLE_PEER_FAILED_VERIFICATION', [52] => 'CURLE_GOT_NOTHING', [53] => 'CURLE_SSL_ENGINE_NOTFOUND', [54] => 'CURLE_SSL_ENGINE_SETFAILED', [55] => 'CURLE_SEND_ERROR', [56] => 'CURLE_RECV_ERROR', [58] => 'CURLE_SSL_CERTPROBLEM', [59] => 'CURLE_SSL_CIPHER', [60] => 'CURLE_SSL_CACERT', [61] => 'CURLE_BAD_CONTENT_ENCODING', [62] => 'CURLE_LDAP_INVALID_URL', [63] => 'CURLE_FILESIZE_EXCEEDED', [64] => 'CURLE_USE_SSL_FAILED', [65] => 'CURLE_SEND_FAIL_REWIND', [66] => 'CURLE_SSL_ENGINE_INITFAILED', [67] => 'CURLE_LOGIN_DENIED', [68] => 'CURLE_TFTP_NOTFOUND', [69] => 'CURLE_TFTP_PERM', [70] => 'CURLE_REMOTE_DISK_FULL', [71] => 'CURLE_TFTP_ILLEGAL', [72] => 'CURLE_TFTP_UNKNOWNID', [73] => 'CURLE_REMOTE_FILE_EXISTS', [74] => 'CURLE_TFTP_NOSUCHUSER', [75] => 'CURLE_CONV_FAILED', [76] => 'CURLE_CONV_REQD', [77] => 'CURLE_SSL_CACERT_BADFILE', [78] => 'CURLE_REMOTE_FILE_NOT_FOUND', [79] => 'CURLE_SSH', [80] => 'CURLE_SSL_SHUTDOWN_FAILED', [81] => 'CURLE_AGAIN', [82] => 'CURLE_SSL_CRL_BADFILE', [83] => 'CURLE_SSL_ISSUER_ERROR', [84] => 'CURLE_FTP_PRET_FAILED', [84] => 'CURLE_FTP_PRET_FAILED', [85] => 'CURLE_RTSP_CSEQ_ERROR', [86] => 'CURLE_RTSP_SESSION_ERROR', [87] => 'CURLE_FTP_BAD_FILE_LIST', [88] => 'CURLE_CHUNK_FAILED', [89] => 'CURLE_NO_CONNECTION_AVAILABLE', [90] => 'CURLE_SSL_PINNEDPUBKEYNOTMATCH', [91] => 'CURLE_SSL_INVALIDCERTSTATUS', [92] => 'CURLE_HTTP2_STREAM' ); ?> |
