You don't have to run make install. In fact, you don't have to run it through Apache at all, just build a CLI binary in your home directory and run sapi/cli/php /path/to/script.php. ------------------------------------------------------------------------ [2006-12-20 08:56:44] youza at post dot cz Use the last CVS is problematic - the server is a production server. I test command ftp_nb_get and this is right. I don't get it why ftp_get is bad and ftp_ng_get is right ? ------------------------------------------------------------------------ [2006-12-19 12:46:22] tony2001@php.net Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip ------------------------------------------------------------------------ [2006-12-19 12:41:10] youza at post dot cz Description: ------------ The ftp_get file transfer generate core dump - [notice] child pid 5999 exit signal Segmentation fault (11), possible coredump in /usr/tmp after reloading WWW this file transfered, but next reload generate new core dump etc.... php = 4.4.4 apache = httpd-2.0.54-10.4 (fedora RPM) Reproduce code: --------------- $ftp_server = 'my_server'; $ftp_user_name = 'my_name'; $ftp_user_pass = 'my_pass'; // define some variables $local_file = 'test_l.dat'; $server_file = 'test.dat'; // set up basic connection $conn_id = ftp_connect($ftp_server); // login with username and password $login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass); // try to download $server_file and save to $local_file $res = ftp_get($conn_id, $local_file, $server_file, FTP_BINARY); if ($res) { echo "<br>Successfully written to $local_file\n"; } else { echo "<br>There was a problem\n"; } // close the connection ftp_close($conn_id); Expected result: ---------------- Transfer the files.
