在PHP中使用数组读取多个文本字段值

Question

Can you please help me in this context.

<form action="sample.php" method="post">
<input type="text" name="first[]" />
<input type="text" name="second[]" />
</form>

I am using this code in a loop and I need to get all the values in another page.
How can I get these value as array in another page.

Answer 1

you should be able to use $_POST array in the sample.php page

PHP's $_POST Array, taken from the docs :

An associative array of variables passed to the current script via the HTTP POST method.

first, add s submit button to your form, it should look like this:

<form action="sample.php" method="post">
  <input type="text" name="first[]" />
  <input type="text" name="second[]" />
  <input type="submit"> 
</form>

and in sample.php :

<?php
print_r($_POST);
?>

This is the most simple example,

once you get the hang of it, I recommend you read the docs on topics such as:

htmlspecialchars

htmlspecialchars — Convert special characters to HTML entities

Answer 2

You can access it as array

$_POST['first'][0] // 0 will be index for single

to list all just loop

foreach($_POST['first'] as $first) {
     ...
}

Answer 3

Your values will end up in $_POST , and because you're using the [] syntax, you'll get an array. So, to get your first array, do:

$first = $_POST['first'];

You could then iterate over it like so:

foreach ($first as $item) {
    ...
}

Answer 4

I think this will help you.

 $first=$_POST['first'];
  $second=$_POST['second'];
  foreach($first as $key=>$first){

   echo 'Your first value'.$first.'Your second value'.$second[$key];
}
