ReflectionExtension::getFunctions()函数是PHP中的内置函数,用于从指定的扩展名返回扩展名函数。
用法:
array ReflectionExtension::getFunctions( void )
参数:该函数不接受任何参数。
返回值:此函数从指定的扩展名返回扩展名函数。
以下示例程序旨在说明PHP中的ReflectionExtension::getFunctions()函数:
程序_1:
<?php
// Defining an extension
$A = 'DOM';
// Using ReflectionExtension() over the
// specified extension
$extension = new ReflectionExtension($A);
// Calling the getFunctions() function
$B = $extension->getFunctions();
// Getting extension functions from
// the specified extension.
var_dump($B);
?>
输出:
array(1) { ["dom_import_simplexml"]=> object(ReflectionFunction)#2 (1) { ["name"]=> string(20) "dom_import_simplexml" } }
程序_2:
<?php
// Using ReflectionExtension() over
// a extension xml
$extension = new ReflectionExtension('xml');
// Calling the getFunctions() function and
// Getting extension functions from the
// specified extension.
var_dump($extension->getFunctions());
?>
输出:
array(24) { ["xml_parser_create"]=> object(ReflectionFunction)#2 (1) { ["name"]=> string(17) "xml_parser_create" } ["xml_parser_create_ns"]=> object(ReflectionFunction)#3 (1) { ["name"]=> string(20) "xml_parser_create_ns" } ["xml_set_object"]=> object(ReflectionFunction)#4 (1) { ["name"]=> string(14) "xml_set_object" } ["xml_set_element_handler"]=> object(ReflectionFunction)#5 (1) { ["name"]=> string(23) "xml_set_element_handler" } ["xml_set_character_data_handler"]=> object(ReflectionFunction)#6 (1) { ["name"]=> string(30) "xml_set_character_data_handler" } ["xml_set_processing_instruction_handler"]=> object(ReflectionFunction)#7 (1) { ["name"]=> string(38) "xml_set_processing_instruction_handler" } ["xml_set_default_handler"]=> object(ReflectionFunction)#8 (1) { ["name"]=> string(23) "xml_set_default_handler" } ["xml_set_unparsed_entity_decl_handler"]=> object(ReflectionFunction)#9 (1) { ["name"]=> string(36) "xml_set_unparsed_entity_decl_handler" } ["xml_set_notation_decl_handler"]=> object(ReflectionFunction)#10 (1) { ["name"]=> string(29) "xml_set_notation_decl_handler" } ["xml_set_external_entity_ref_handler"]=> object(ReflectionFunction)#11 (1) { ["name"]=> string(35) "xml_set_external_entity_ref_handler" } ["xml_set_start_namespace_decl_handler"]=> object(ReflectionFunction)#12 (1) { ["name"]=> string(36) "xml_set_start_namespace_decl_handler" } ["xml_set_end_namespace_decl_handler"]=> object(ReflectionFunction)#13 (1) { ["name"]=> string(34) "xml_set_end_namespace_decl_handler" } ["xml_parse"]=> object(ReflectionFunction)#14 (1) { ["name"]=> string(9) "xml_parse" } ["xml_parse_into_struct"]=> object(ReflectionFunction)#15 (1) { ["name"]=> string(21) "xml_parse_into_struct" } ["xml_get_error_code"]=> object(ReflectionFunction)#16 (1) { ["name"]=> string(18) "xml_get_error_code" } ["xml_error_string"]=> object(ReflectionFunction)#17 (1) { ["name"]=> string(16) "xml_error_string" } ["xml_get_current_line_number"]=> object(ReflectionFunction)#18 (1) { ["name"]=> string(27) "xml_get_current_line_number" } ["xml_get_current_column_number"]=> object(ReflectionFunction)#19 (1) { ["name"]=> string(29) "xml_get_current_column_number" } ["xml_get_current_byte_index"]=> object(ReflectionFunction)#20 (1) { ["name"]=> string(26) "xml_get_current_byte_index" } ["xml_parser_free"]=> object(ReflectionFunction)#21 (1) { ["name"]=> string(15) "xml_parser_free" } ["xml_parser_set_option"]=> object(ReflectionFunction)#22 (1) { ["name"]=> string(21) "xml_parser_set_option" } ["xml_parser_get_option"]=> object(ReflectionFunction)#23 (1) { ["name"]=> string(21) "xml_parser_get_option" } ["utf8_encode"]=> object(ReflectionFunction)#24 (1) { ["name"]=> string(11) "utf8_encode" } ["utf8_decode"]=> object(ReflectionFunction)#25 (1) { ["name"]=> string(11) "utf8_decode" } }
