gmp_mod()

[systech44]

Hi,
Please help to solve the following problem using gmp_mod(). I bring the function from PHP Manual, but it is not working. Please help.

<?php

$mod = gmp_mod("8", "3");
echo gmp_strval($mod) . "\n";

?>

Thanks in advance.

What does "not working" mean, exactly?

[visualAd]

The GMP library is probably not compiled or enabled.

I am getting the following error.

Fatal error: Call to undefined function: gmp_mod() in /home/go/public_html/test/mod.php on line 3

Please help me to solve it out.

Many thanks.

It might be good to check if your version of php was built with GMP support.

Create a page to check:

phpinfo();

Visit this page -- do you see a section like this:

gmp
gmp support 	enabled

]

or at least, under the Configure Command section, the text '--with-gmp' ?

[systech44]

Thanks sunburnt,

No, I am not getting anything from phpinfo();

Please tell me how to cope it up.

Waiting for the reply.

Thanks.

If you are using windows you need to go to your php.ini and enable the line: extension = gmp.dll.

If you are using Linux, you need to recompile PHP with --with-gmp or compile and enable the gmp.so.

See: http://us3.php.net/gmp

I found this line

;extension=php_gmp.dll

in php.ini file and I make it like this

;enabled extension=php_gmp.dll

But my program is not working. Please help.

To enable it you need to remove the ";" from thje beginning of the line. No need to type enabled.

Fatal error: Call to undefined function: gmp_mod() in /home/go/public_html/test/mod.php on line 3

Check your extension path and check that directory contains the php_gmp.dll file.

[systech44]

directory path:
C:\Program Files\LuckaSoft\EnginSite Editor for PHP\php\PHP-5.2.3\ext

Please help.

Well does php_gmp.dll exist?

[systech44]

Yes it exists. Please help.

[visualAd]

Does the extension path setting in PHP point to the directory in which it exists?

[systech44]

What is the extension path setting in PHP and how to observe it. Please help.

[visualAd]

The setting is in the php.ini:

http://de3.php.net/manual/en/ini.cor....extension-dir

It is called extension_dir and it needs to be set to either an absolute path i.e: one starting with C:\ or a path relative to the PHP.ini.
