我陷入了项目的一部分，我需要将我在数据库中输入的复选框输入与另一个值进行比较。
我需要使用explode拆分输入并比较每个值以查看它们中的任何一个是否与输入列表匹配。如果它们中有任何一个，我想回应那些匹配的值。
拆分输入有效，但比较不起作用。以下是我的代码。
<?php
$cou = explode(',' , $row_rsCourse['courses']);
foreach($cou as $mark){
$mark1 = $mark."<br>";
}
if ($mark1 = $row_rsCourselist['code'] ){echo $row_rsCourselist['name'];}else {echo "Failed";}
?>
/*
For example:
$row_rsCourse['courses'] = (a,b,d,g,i)
$row_rsCourselist['code'] = is a database column which contains letters a - z in different input
$row_rsCourselist['name'] = is a database column which contains names from a - z in different inputs e.g (Andre Ben Charlie etc)
*/
以下是完整的源代码

答案 0 :(得分：0)
我使用了“行”和“行”，以便更清楚地看到正在发生的事情，而不是您正在使用的实际$ row_rsCourse。它更清洁，更容易让别人看到。你需要做一些编辑才能完成这项工作，但你应该得到你需要的东西。请记住，您正在使用POST来获取PHP复选框的值。
<?php
// Set the value of your input to a variable
$input_value = isset($_POST['your_checkbox_name']);
// You also need to set an array of all of the rows in the database that have code, name, course, etc.
$rows = your_rows_in_the_database;
// for each row in the database that has a code, name, course, etc.
foreach($rows as $row){
// If your input value matches with $row['code'] of the current object in the loop
if ($input_value == $row['code']) {
// Whatever you want to echo out
echo $row['name'];
} else {
echo 'No matches were found';
}
}
?>
