[PHP-DEV] Re: PHP 4.0 Bug #7880 Updated: PHP_URL_FOPEN doesn't work From: Alan Halachmi (alan <email protected>)
Date: 12/04/00

php-de>a. Remake and make sure that gcc is being called with -g. b. do a gdb httpd
php-de>c. run -X
php-de>d. hit ctrl-c (it might take a while to catch)
php-de>e. break php_fopen_wrapper
php-de>f. cont
php-de>g. open your test-script while its waiting
php-de>h. it should break when it trys to make the file request
php-de>i. hit n to step to the next line of code
php-de>j. see if it ever hits if(!(options & IGNORE_URL)){
php-de>k. if url wrappers is not compiled you would get
php-de> if (options & USE_PATH........ instead
php-de>and just replace the '$fp=file($url)' line with '$fp=fopen($url,"r")'
