开发时遇到叫用函数 错误.
可能原因应该是dll未加载.
这边可以使用 方法测试.?
get_extension_funcs
官方说明如下:
http://php.net/manual/en/function.get-extension-funcs.php
function testGD(){
$testGD = get_extension_funcs("gd"); // Grab function list
if (!$testGD){ echo "GD not even installed."; exit; }
echo"
".print_r($testGD,true)."
";
}
若未加载, 会输出?GD not even installed.
这是官方的范例:
会输出如下内容.
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

[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
