Count函数在PHP中不起作用以查找数组的大小

Question

$datas = array();

while($row = mysql_fetch_array($firstQueryResult)) {
    $phones["Id"] = $row['person_id'];
    $phones["Latitude"] = $row['lat'];
    $phones["Longitude"] = $row['lng'];
    $phones["Distance"] = $row['distance'];
    $phones["DateTime"] = $row['location_datetime'];
    $datas["mydata"][] = $phones;
}

echo "Count = ".count($datas); // always returning 1 while i have more than 1 recor
echo "Count = ".sizeof($datas); // always returning 1 while i have more than 1 record

任何人都可以帮助我。

Answer 1

试试这个

echo "Count = ".count($datas['mydata']);
echo "Count = ".sizeof($datas['mydata']);

Answer 2

$ datas只有1个元素 - ＆gt; “MYDATA”。

您想要计算mydata中的条目数，所以：

count($datas["mydata"]);
