如何从单个文本框中获取多个值并将其存储在数组中以及如何将其存储在数据库中

Question

Can I use php to get multiple values from one input text box and store it in array? I want to read multi integers from the user and store it in array For example, I add one input text and one submit:

Answer 1

You could do it in this way.

Make an form in HTML having an input which should take comma seperated integer values like this:

<form action="url" method="POST">
    <input id="dataInput" type="text" name="data" value="12,34,56">
    <button id="submitBtn">Submit</button>
</form>

Now on submitting the form, you should receive the data in PHP, and you can use php's explode method like this:

<?php

$data = $_POST['data'];
$data_arr = explode(',', $data); // <----- explode the string here from commas
// Now you can store these values into the database

So the output for the $data_arr would be:

$data_arr = array(
    0 => '12',
    1 => '34',
    2 => '56'
);

Hope this helps!

Answer 2

Use explode () function Then array_walk () function to make sure you get the NUMERIC values

<?php

// Assuming your method is POST 
// and assuming the delimiter (entered by user) is UNITED as a COMMA "," 
$_POST['input_name'] = explode(",", $_POST['input_name']);
$_POST['input_name'] = array_walk($_POST['input_name'], 'floatval');

?>
