你好,
我有这个代码很好用
function show_aval($place) {
echo $place;
}
ob_start();
show_aval(london);
$show_aval = ob_get_contents();
ob_clean();
ob_start();
show_aval(york);
$show_aval2 = ob_get_contents();
ob_clean();
ob_start();
show_aval(liverpool);
$show_aval3 = ob_get_contents();
ob_clean();
但我想像这样简化这段代码:
$avalrooms = [];
$cities = ["london", "york", "liverpool"];
foreach ($cities as $city) {
ob_start();
show_aval($city);
$avalrooms[$city] = ob_get_contents();
ob_clean;
}
但是,这似乎无效ob_get_contents
,因为该功能正在按show_aval($city);
所述立即执行。
为什么会这样?
谢谢你。
