        [99] => 0.0
        [100] => 3.0

    )

我想删除0.0怎么能轻易做到请帮帮我我想用循环

来做这个

Answer 1

您可以使用＆＃39; array_filter＆＃39;从PHP函数过滤null，空字符串或0.0值

$array = array_filter($array);

Answer 2

我会选择上面的Benz回答

但另一种选择可能是array_diff：

$remove = array(0.0);
$filtered = array_diff($source_array, $remove);

Answer 3

function is_zero($string) {
    $remove = array("0", "0.0");
    if (in_array($string, $remove)) {
        return FALSE;
    }
    return TRUE;
}

$clean_array = array_filter($your_array, "is_zero");

这将删除0或0.0的所有内容。使用强制转换比较（int / float）可能比检查字符串更好......

在array_filter（）

上查看http://php.net/manual/en/function.array-filter.php有关信息的信息

Answer 4

您可以尝试以下操作：

<?php

$array=array('0.0','0.0','0.0','0.0','0.0','0.0','0.0','0.0','2.0','13.0','17.0','3.0');

function myFilter($string) {
  return strpos($string, '0.0') === false;
}

$newArray = array_filter($array, 'myFilter');

echo '<pre>';
print_r($newArray);
echo '<pre>';

?>

从php数组中删除特定字符
