Detailed description of php checkbox value_PHP tutorial

Suppose we have an html page with the following code:

Copy the code The code is as follows:

Pay attention to the name attribute of the input above. The content of each attribute is the same, and they are all test[]. The reason for adding [] is to transfer the content of test into an array. The code content of
checkTest.php is as follows:

Copy code The code is as follows:

echo implode(",",$_POST['test']);
?>

When we output the content, we only need to pay attention to using the implode function to convert the array content into a string. .
Note: This function can be used in situations such as deleting multiple records. For example, Delete from tbl where ID in (implode(",",$_POST['test'])).
Example code:

Copy code The code is as follows:

< ;title>Untitled document


If the html checkbox is to be sent to the php script for processing in the form of a data group, it must be in the form of checkbox[ ]This form

//Determine whether to click submit
if( $_POST)
{
$array = $_POST[' checkbox'];
print_r($array);
}
/*
Result:
Array
(
[0] => 1
[1 ] => 2
[2] => www.jb51.net
[3] => jb51.net
)
Many simple things feel complicated before you do them, but when you do them It's easy, just like this checkbox code.
