Eregi problems moving to preg-match

[yobo]

Hey all I have some old code that i did a while back but now that I am running php 6 it says the eregi function is depreciated I have tried replacing this old function with preg-match but I am unable to do so I was wondering if you all good take a look at my coding and see how i can remove the validation check altogether

 

I have two pages the first page processes the orders

<?php
/* Program name:  ProcessOrder.php
  * Description:   Processes order when it's been submitted.
  */
session_start();                                         #5
include("functions_main.inc");
if(!isset($_SESSION['order_number']))                    #7
{
   echo "No order number found<br>\n";
   header("Location: ShopCatalog.php");
   exit();
}
if(@$_GET['from'] == "cart")                            #13
{
   include("fields_ship_info.inc");
   include("single_form.inc");
   exit();
}
elseif(isset($_POST['Summary']))                        #19
{
   foreach($_POST as $field => $value)                  #21
   {
      if ($value == "")
      {
         $blanks[] = $field;
      }
   }  
   if(isset($blanks))
   {
      $message = "The following fields are blank. 
                  Please enter the required information:  ";
      foreach($blanks as $value)
      {
         $message .="$value, ";
      }
      extract($_POST);
      include("fields_ship_info.inc");
      include("single_form.inc");
      exit();
   }
   foreach($_POST as $field => $value)                  #41
   {
     if($field != "Summary")
     {

have a look at this

 

<?php 
if(ereg('[^0-9A-Za-z]',$test_string)) // will be true if characters arnt 0-9, A-Z or a-z. 

if(preg_match('/[^0-9A-Za-z]/',$test_string)) // this is the preg_match version. the /'s are now required. 
?>

Sorry ignore that post above, I used ereg which has been removed...

 

<?php
// The "i" after the pattern delimiter indicates a case-insensitive search
if (preg_match("/php/i", "PHP is the web scripting language of choice.")) {
    echo "A match was found.";
} else {
    echo "A match was not found.";
}
?>

 

Have a look at that.
