PHP代码在一台服务器上运行，而不是在另一台服

Question

My development server runs my PHP web application smoothly on PHP 5.3.8.

However, when upgrading my PHP production server from PHP 5.2.6 to 5.3.8 I got several problems with this application (complaints about deprecated function ereg_replace and missing date.timezone settings) which forced me to order a rollback to 5.2.6.

How can the same PHP code work fine on one 5.3.8 server and not on another? What are common causes for this behavior? Any suggestions?

Answer 1

Please access php.ini (PHP configuration file) on both server. Find the line "; display_errors"

Please compare the following lines after that.

These are the options available for the three settings variable:

; display_errors
;   Default Value: On
;   Development Value: On
;   Production Value: Off

; display_startup_errors
;   Default Value: Off
;   Development Value: On
;   Production Value: Off

; error_reporting
;   Default Value: E_ALL & ~E_NOTICE
;   Development Value: E_ALL | E_STRICT
;   Production Value: E_ALL & ~E_DEPRECATED
