A while ago, the test server on the PHP version did an upgrade, and later in the development of debugging, access to find a blank page, after grabbing the packet found that HTTP code is 500, in PHP error log record a fatal error, can't help but a bit confused, because before the test machine, Even if the fatal error, there will be output on the page, HTTP code is 200, and should not be 500, so in the local test, found that this is true, then exactly why, the test server appears fatal error will return 500 HTTP code, and the local output error and return HTTP code 200?
Comparing the two configuration files, found that the test server above Display_error set to OFF, and the local display_error set to ON, then the answer is clear:
When Display_error is on, output error and return 200
When Display_error is off, no error is output and 500 is returned
The above describes PHP in the fatal error 500, including the content, I hope that the PHP tutorial interested in a friend helpful.
