问题
A simple php_curl example isn't working anymore on my Windows 10 laptop. It was working before.
Fatal error: Uncaught Error: Call to undefined function curl_init() in C:\Users\path\curl.php:3 Stack trace: #0 {main} thrown in C:\Users\path\curl.php on line 3
My C:\php7\php.ini has extension=C:\php7\ext\php_curl.dll
php_curl.dll exists in C:\php7\ext
PHP Version 7.0.30
Windows 10 Pro Version 1607 Build 14393.2189
But my loclahost/phpinfo.php does not have cURL. How come all of a sudden it disappeared ?
PS : The script worked in the command line. It's just that Apache is not loading the extension.
回答1:
don't know why it suddenly stopped working, but first run <?php phpinfo(~0); , and check which php.ini file that is actually loaded (this avoids editing the wrong php.ini file to no avail) (in this example, it is /etc/php/7.0/fpm/php.ini), then edit that php.ini file, if that file actually has the extension=C:\php7\ext\php_curl.dll line, then some combination of the following settings are set wrong:
display_startup_errors is Off, change it to On
display_errors is Off, change it to On
error_reporting is not E_ALL, change it to error_reporting=E_ALL (and nothing else, not like error_reporting= E_ALL & ~E_NOTICE or whatever, just E_ALL)
html_errors is Off, change it to On
then restart apache, again check the phpinfo() page, and verify that the new configuration options are actually loaded, then run <?php curl_init();, and it should show an error about why the curl extension could not be loaded.

I came across some links on other StackOverflow answers (will post the links here if I trace them again). I had Apache 2.4.23 Win64 - I reinstalled Apache to the latest one - 2.4.33 Win64 - and now cURL is working.
