You can say No, but I just did extensive testing. I have multiple php disabled. I use php55m as branch used. In any phpinfo() it says configuration loaded: /opt/php55m/custom/php.ini
In this php.ini:
;### MR -- custom setting (handle by kloxo)
disable_functions = exec,passthru,shell_exec,system,proc_open,popen,show_source
I have NO disabled function in KloxoMR panel with exec or shell_exec. In phpinfo() it DOES NOT list them as disabled but when trying to use them, security warning is given.
I simply:
In /opt/php55m/custom/php.ini
;### MR -- custom setting (handle by kloxo)
;disable_functions = exec,passthru,shell_exec,system,proc_open,popen,show_source
Commented out and now all works. If I change disabled functions in admin php configuration, it works. I can add, remove exec etc.
When running fixphp script /opt/php55m/custom/php.ini does not get updated. You need to comment out disabled functions in all php5*x/custom/php.ini files.
Test. I have over and over.
