出于安全原因，print_r（）已被禁用使用Codeigniter [关闭]

Question

I'm Using codeigniter 3.1.6

print_r() has been disabled for security reasons this type of error regenerated so how to fixed it.

Answer 1

check the disable_function entry in the php.ini file, print_r is probably disabled there. Issue is most likely not related to Codeigniter.

if you have no access to php.ini file, you can check the configuration by using the phpinfo() from a Codeigniter Controller and see if the print_r function is disabled.
