剧本:
<?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);
?>
我在“some_text_id”列的一行中有以下条目:
164, 165, 166
我希望用逗号“爆炸”它并将它存储在一个数组中,所以我可以单独选择数字,例如:
myarray[0], myarray[1], myarray[2]
虽然我收到以下错误消息:
警告:explode()期望参数2为字符串,数组以...给出(指向爆炸函数)
有关如何执行此操作的任何建议吗?

跳过将数据库结果放入数组的部分。这完全没必要:
<?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);
?>
