Bug #12748 Updated: changing allow_url_fopen from "off" to "on" crashes fopen()

ID: 12748 User updated by: phpman@toowards.com Reported By: phpman@toowards.com Status: Open Bug Type: Reproducible crash Operating System: redhat-7.1b PHP Version: 4.0.6 New Comment: See #13633 which describes a similar problem - I am not alone :-) Previous Comments: ------------------------------------------------------------------------ [2001-08-18 05:56:51] phpman@toowards.com Also, phpinfo() shows a blank cell for the 'Master Value' and "1" for the 'Local Value' of 'allow_url_fopen' when using; in php.ini: allow_url_fopen = Off & in httpd.conf php_admin_flag allow_url_fopen On I tried using "allow_url_fopen = 0" (Master Value becomes "0", fopen() still crashes). I also tried "php_admin_value allow_url_fopen 1" (Local Value still "1", fopen() still crashes). When I leave out the setting in httpd.conf, and just have "allow_url_fopen = Off" in the php.ini file, phpinfo() has "no value" written for the Master Value and Local Value. Maybe this helps? ------------------------------------------------------------------------ [2001-08-18 05:23:43] phpman@toowards.com Todays snapshot - php4-200108180135.tar.bz2 - still shows the problem.
