Accessing variables in PHP files - php

Question

Is there anyway to access variables of one php file into another?
- I am trying to validate a form. I need to access variables from the validationConditions.php file in form.php file.
I have tried creating sessions but they are error prone.
I am using the latest version of dreamweaver.
Is it possible to use $_POST to achieve the results?
Any example will be welcome...
Thanks a lot in advance.

Answer 1

The easiest would be to use session variables. In the first page you could set the values like this
session_start();
$_SESSION['myvar'] = 'My Data';
Then in the second page you can retrieve the data like this...
session_start();
$myvar = $_SESSION['myvar'];
Which in turn sets $myvar to "My Data"

Answer 2

You can read a php file with another php file. Assume that we have 2 php files.
new.php
<?php
$a="something";
?>
serach.php ---> search in new.php
<?php
// What to look for
$search = '$a'; //WE are searching $a
$lines = file('new.php'); // in new.php
foreach($lines as $line)
{
// Check if the line contains the string we're looking for, and print if it does
if(strpos($line, $search) !== false)
echo $line;
}
?>
Something like that. You have to edit this file.

A somehow devious solution:
ob_start();
$request = array(
"_id"=>"0815",
"user"=>"john",
"email"=>"john#dunbar.com",
"phone"=>NULL
); // Don't know. Just how u need your request to look like.
include('validationConditions.php');
$response = getValidationConditions($request); // Function in 'validationConditions.php' that responds an array or a JSON
$out = ob_get_clean();
echo json_encode($out);
