get_extension_funcs 


php128 apg

GETS an ARRAY with the names of the functions of a module.



<?php

array|false get_extension_funcs string $extension )

where,

$extension Name of the extension to be checked
                          
                          One of the extension names 
                          obtained through the 
function:
                          
get_loaded_extensions 
?>
 

  $extension   


The module name to get the extension functions.




In order to have a complete list of all the functions available in each of the installed extensions, we use get_loaded_extensions which provides the names of said extensions in the format of an ARRAY.


<?php
              
array get_loaded_extensions([ bool $zend_extensions FALSE ] ) 


where

$zend_extensions = if TRUE only return Zend extensions 
                             The 
default, FALSE return regular extensions 

?>
 


So, we use get_extension_funcs to know the names of the functions available in each extension.

Therefore, run the next exercise to see what functions are available in each extension present in your system.

For arbitrary precision mathematics PHP offers the Binary Calculator which supports numbers of any size and precision up to 2147483647, (or 0x7FFFFFFF), decimals, if there is sufficient memory, represented as strings.

We will study all MATHEMATICS functions available in the bcmath extensions.

As this depends on the PHP version, run the next exercises on your system.
