Question

在类里面调用自定义函数提示函数未定义

class Test
{
function __construct()
{
;//空构造函数
}
public
function testFun()
{
testChildFun();
}
private function
testChildFun()
{
echo "Test Success!";
}
}

然后

$myTest
= new Test();
$myTest ->testFun();

就提示:
PHP Fatal error: Call to
undefined function testChildFun() in
...
testChildFun()我明明已经定义了啊～～难道要事先声明么?

Answer 1

public function testFun()
{
$this->testChildFun();
}
