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:

<?php
echo "<pre class="brush:php;toolbar:false">";
print_r(get_extension_funcs("JSON"));
echo "<br>";
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:
