How to keep all the POST information while redirecting in PHP?

header('Location: ' . $uri);

This will miss all the $_POST information.

if u want to carry forward your POST data to another pages ( except the action page) then use

session_start();
$_SESSION['post_data'] = $_POST;

You can use is_uploaded_file():

if(!file_exists($_FILES['myfile']['tmp_name']) || !is_uploaded_file($_FILES['myfile']['tmp_name'])) {
    echo 'No upload';
}

From the docs:

Returns TRUE if the file named by filename was uploaded via HTTP POST. This is useful to help ensure that a malicious user hasn't tried to trick the script into working on files upon which it should not be working--for instance, /etc/passwd.

This sort of check is especially important if there is any chance that anything done with uploaded files could reveal their contents to the user, or even to other users on the same system.

EDIT: I'm using this in my FileUpload class, in case it helps:

public function fileUploaded()
{
    if(empty($_FILES)) {
        return false;       
    } 
    $this->file = $_FILES[$this->formField];
    if(!file_exists($this->file['tmp_name']) || !is_uploaded_file($this->file['tmp_name'])){
        $this->errors['FileNotExists'] = true;
        return false;
    }   
    return true;
}

you would need 2 forms on your page, one form that posts back to index.php and a second form that posts to paypal

after the first form posts back to index.php, echo javascript in the body tag to submit the paypal form when it loads

    <?php
   if(isset($_POST['mydatafield'])){

        do database stuff

        $LOAD = 'document.paypal.submit();';
    }
    ?>
    <body onload="<?php echo $LOAD ?>">
    <form name="paypal" action="paypal.com?yadayada">
    paypal fields
    </form>
    <form name="myform" action="index.php">
    your form stuff
    submit button
    </form>

Your post data is JSON so use json_decode to turn it into an array containing anobject and access the object_id property

$rawPostData = file_get_contents('php://input');
$json = json_decode($rawPostData);
$json = $json[0];
$all = date("F j, Y, g:i a") . " " . $json->object_id. "rn";
file_put_contents("Activity.log", $all, FILE_APPEND);

$array = array('3X' => '3X','EX'=> 'EX','VG'=>'VG','G'=>'G','F'=>'F','P'=>'P');
$start = "3X";
$end ="F";
$new_array = [];
$i=0;$go=false;
foreach ($array as $element) {
    if($go){
        $new_array[$i] = $element; 
        $i++;
    }
    if($element==$start){
        $go = true;
    }
    if($element==$end){
        $go = false;
    }
}
$total_elems_new = count($new_array);
unset($new_array[$total_elems_new-1]);
print_r($new_array);
