使用PHP在同一页面上获取输入值？

Question

Well, first i'm new in PHP. Is there a way to get the input value from a existing input on the page on page load with php and pass it to a variable?

For example i have this input: <input type="text" name="g_id_p" id="example1" value"foo">

I want to do something like this: $got_it = $_GET['g_id_p'];

Sorry again if i wrote my code wrong, im noobie on this. Hope to someone help me.

You can't really get an associated value of an input tag within the same PHP page but what you can do is set the value of a variable beforehand.

What I mean is, create an array that will store all the values of all the input tags.

$inputValues = array();
$inputValues['g_id_p'] = 'foo';

Then when you have the tag later on just echo it from the PHP var.

<input type="text" name="g_id_p" id="example1" value="<?php echo $inputValues['g_id_p']; ?>">

As you can see, we aren't really 'getting' the value that you set but the end result is the same.
