Undefined function ctype_digit

[Mahngiel]

Ok, this is awkward.  I compiled my version of 5.4.6 on this test partition, and hadn't had any errors until a few minutes ago when I came across this error.  Now, according to the manual, you've had to explicitly --disable-ctype since like... 4.3.  Also, according to the docs, there is no runtime config setting for this. 

 

So... dufuq? and how do i fix it?

[Mahngiel]

thanks for the move, thorpe. sorry bout that.

phpinfo?

Are you sure about the code/exact error message? Perhaps you have a typo in the function name.

Namespaces? For kicks try calling \ctype_digit. And then see if the other functions called below work.

Actually, I think the problem lies with the PHP CLI parser, and not namespaces.

I noticed that you took the phpinfo () dump from a web page, and thus went via the browser (and by extension the CGI executable). Then tried running the code via the CLI executable, and getting the error. I Just did something similar, with json_encode ():

php > var_dump (json_encode ($test));
PHP Fatal error:  Call to undefined function json_encode() in php shell code on line 1

 

However, when I saved it to a file, and ran it via the web server, everything worked just fine. So check what phpinfo () states for the CLI version, and I think you'll be enlightened.

I quite think you're onto something, @CF.  I ran a dumped a test.php file and there's zero mention of ctype being in there. Now, as seeing as the browser version told me it was enabled, I'm not sure if it was disabled would there be an entry stating thusly or not.  Here's a bit of cli

 

mahngiel@studio46 ~ $ php test.php > output.txt
mahngiel@studio46 ~ $ cat output.txt | grep 'ctype'
mahngiel@studio46 ~ $ cat output.txt 
phpinfo()

Now, at this point I'm not sure if I need to recompile or what.  That function is pretty important to my cron jobs, so I've temporarily replaced ctype_digit() with is_numeric(). 

 

What should I do at this point?

[Christian F.]

It's this part that's messing up for you:

'--disable-all'

 

So if you really need the ctype functions, you have a few options available:

• Recompile PHP-CLI, with --enable-ctype in addition to the flags listed above.
  
• Write your own validation functions, and use them instead.
  
• Run the script via the local web-server.

Last option being a lazy hack, but..
