Use PHP functions in PHP extension

Question

Can I use a PHP function such as explode() when creating an extension in C++?

Answer 1

Here it is: PHP_FUNCTION(explode) expands to zif_explode with these parameters. That's the function you should call.

Answer 2

PHP functions are usually implemented as parameter type checks followed by calling a native function, usually with the same name prefixed by php_.

For example, explode calls either php_explode or php_explode_negative_limit depending on the value of the third parameter (look at the source).

You can get the prototypes for these by including <ext/standard/php_standard.h>.

Make sure to check the implementation of the original PHP function for the preconditions on the arguments.
