PHP - Fatal error: Call to undefined function

[erasam]

Recently i am doing a php project which involves the usage of RS232 interface (COM PORT)

 

I have find an example but i don't know how to run it.

 

I have followed the instruction given in the readme file, but when i run php/iol_info.php, it said

Fatal error: Call to undefined function iol_info() in c:\AppServ\www\class\php_iol.class.php on line 35

 

So, how can it solve this problem. Plz help me.

fatal error means that your version of php isn't compiled to use that function

 

echo php_info

and see the php manual on that function to see what library, and what version of php you need to use that function

 

if your php does support that function make sure you are using the correct syntax with the function, see the php manual for details on that syntax

 

BUT fatal always means your version of php doesn't support it, period
