警告：explode（）期望参数2为字符串，给定[闭合]数组

Question

The Script:

<?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":

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.:

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

Though I am getting the following error message:

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

Any suggestions on how to do this?

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

<?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);

?>
