@stereorog：我同意，还要检查['printf（）的'变换器]（HTTP：//键盘。 viper-7.com/eVhuuJ）[hakre]（http://stackoverflow.com/users/367456/hakre）。 – alex

首先它不是数组的数组，而是数组的对象。只要循环他们，并进行有条件检查。像这样：

<?php 
$with_hits = array(); 
foreach ($objects as $object){ 
    if ($object->hits > 0){ 
    $with_hits[] = $object; 
    } 
} 
?>

答

您可以使用array_walk或array_map功能测试hits。

$hits = array(); 

function fill_hits($key, $item) 
{ 
    global $hits; 
    if ($item->hits > 0) $hits[] = $obj; 
} 

array_walk('fill_hits', $array);

假设> = PHP 5.3 ...

$newArr = array_filter($arr, function($obj) { 
    return $obj->hits > 0; 
});

参数需要交换。 –

<?php 
$ret = array(); 
foreach($data as $key => $obj) { 
    if($obj->hits > 0) { 
     $ret[$key] = $obj; 
    } 
} 

print_r($ret); // your filtered data here 

?>
