I noticed that sometimes, when I lose Internet connection and I try to run PHP interactively from the command line:
$ php -a
It hangs. I really have to wait several seconds before seeing the interactive prompt:
$ php -a
Interactive shell
php >
After investigating and changing different configuration values of the php.ini used by the command line command, I found out that the problem was the IMAP extension:
; within the php.ini loaded by the php CLI command
; ...
extension=imap.so
; ...
If, while not having lost Internet connection, I comment that line:
; within the php.ini loaded by the php CLI command
; ...
;extension=imap.so ; <--- Comment it
; ...
And run php -a from the CLI, I can instantly see the interactive prompt:
$ php -a
Interactive shell
php >
My guess is that the imap.so extension is making a network call when I bootstrap PHP and when I lose Internet connection, it hangs before reaching a time out of several seconds and showing me the prompt.
Why does imap.so behave like this?
Thank you for your attention.
EDIT:
I retried to run $ sudo dtruss php -a several times, here is what it shows while it hangs (before seeing Interactive sheel from the bottom, I have omitted the higher lines because the output would exceed 30000 characters otherwise):
$ sudo dtruss php -a
