PHP | ReflectionExtension getFunctions()函数
ReflectionExtension::getFunctions()函数是PHP中的一个内置函数,用于从指定的扩展返回扩展函数。
句法:
array ReflectionExtension::getFunctions( void )
参数:此函数不接受任何参数。
返回值:该函数从指定的扩展返回扩展函数。
下面的程序说明了PHP中的 ReflectionExtension::getFunctions()函数:
程序_1:
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:
getFunctions());
?>
输出:
