str_replace help needed

[smith.james0]

I have the following code to replace some values in a template

$page_contance_before = file_get_contents('includes/contact.php');                    

$postname = $_SESSION['post']['name'];
$postemail = $_SESSION['post']['email'];
$postmessage = $_SESSION['post']['message'];
$None = $_SESSION['n1'];
$Ntwo = $_SESSION['n2'];


$PAGE_VARScontact = array(
                 'NAME' => $postname,
                 'EMAIL' => $postemail,
				 'MESSAGE' => $postmessage,
				 'None' => $None,
				 'Ntwo' => $Ntwo,
               );
               
print_r($PAGE_VARScontact);

foreach ($PAGE_VARScontact as $K => $V) {       
   $page_contance = str_replace("{".$K."}",$V,$page_contance_before);
   echo "k $K - v $V <br />";
}	

 

The problem I have is only 'Ntwo' is being replaced, if I delete 'Ntwo' => $Ntwo, from the array, then only 'None' gets replaced. Why is it only replacing the last value in the array, I have the same code working else were in the site no problem!

$page_contance = str_replace("{".$K."}",$V,$page_contance_before);

Because you keep replacing from the original string, not the one that has previous replacements.

A less resource intensive solution would be:

 

 

$search = array("{NAME}", "{EMAIL}", "{MESSAGE}", "{none}", "{Ntwo}");
$replace = array($postname, $postemail, $postmessage, $None, $Ntwo);
$page_contance = str_replace($search, $replace, $page_contance_before);
