警告:explosion()期望参数2是string，数组给定

The Script:

脚本:

<?php

    $tqs = "SELECT * FROM `table_two`";
    $tqr = mysqli_query($dbc, $tqs);
    $row = mysqli_fetch_assoc($tqr);
    $thearray[] = $row['some_text_id'];

    // Prints e.g.: Array ( [0] => 164, 165, 166 )
    print_r($thearray);

    echo "<br/><br/>";
    echo "<br/><br/>";

    $thearray = explode(", ", $thearray);
    print_r($thearray);

?>

I have the following entry in one row of the column "some_text_id":

在“some_text_id”列的一行中有以下条目:

164, 165, 166

I am looking to "explode" this by the comma and have it stored in an array, so I can select the numbers individually, e.g.:

我希望用逗号“爆炸”它，并将它存储在一个数组中，因此我可以分别选择数字，例如:

myarray[0], myarray[1], myarray[2]

Though I am getting the following error message:

虽然我得到以下错误信息:

Warning: explode() expects parameter 2 to be string, array given in ... (points to the explode function)

警告:explosion()期望参数2是string，数组在…(指向爆炸函数)

Any suggestions on how to do this?

有什么建议吗?

Skip the part where you put the database results into an array. It's completely unnecessary:

跳过将数据库结果放入数组的部分。这是完全不必要的。

<?php

    $tqs = "SELECT * FROM `table_two`";
    $tqr = mysqli_query($dbc, $tqs);
    $row = mysqli_fetch_assoc($tqr);

    // Prints e.g.: 164, 165, 166
    print_r($row['some_text_id']);

    echo "<br/><br/>";
    echo "<br/><br/>";

    $thearray = explode(", ", $row['some_text_id']);
    print_r($thearray);

?>
