How to get the function name of a module in PHP

PHP obtains the function name of the module, which can be achieved through the get_extension_funcs function. Such as searching XML, JSON functions.

Let’s use code examples to introduce how to get module function names in PHP.

The code example is as follows:

"; print_r(get_extension_funcs("JSON")); echo "
"; print_r(get_extension_funcs("XML"))."\n";

The output result is as follows:

Array ( [0] => json_encode [1] => json_decode [2] => json_last_error [3] => json_last_error_msg ) Array ( [0] => xml_parser_create [1] => xml_parser_create_ns [2] => xml_set_object [3] => xml_set_element_handler [4] => xml_set_character_data_handler [5] => xml_set_processing_instruction_handler [6] => xml_set_default_handler [7] => xml_set_unparsed_entity_decl_handler [8] => xml_set_notation_decl_handler [9] => xml_set_external_entity_ref_handler [10] => xml_set_start_namespace_decl_handler [11] => xml_set_end_namespace_decl_handler [12] => xml_parse [13] => xml_parse_into_struct [14] => xml_get_error_code [15] => xml_error_string [16] => xml_get_current_line_number [17] => xml_get_current_column_number [18] => xml_get_current_byte_index [19] => xml_parser_free [20] => xml_parser_set_option [21] => xml_parser_get_option [22] => utf8_encode [23] => utf8_decode )

Function introduction:

get_extension_funcs() function, returns an array of module function names.

array get_extension_funcs ( string $module_name )

This function returns the names of all functions defined within the module based on module_name.

The parameter module_name is the module name.

Note: This parameter must be lowercase (lowercase).

Return value, returns an array containing all function names, or returns FALSE if module_name is not a valid extension.
