Get some text with CURL and parse only the variables inside with PHP -

php getting external text variable curl domain like: https://somedomain.com/file.txt

this file.txt contains text , variables inside like:

welcome our $storename store, $customername

our store located @ $storeaddress in somewhere.

you see text contains variables inside.

when text in php file in domain like: https://example.com/emailer.php

this emailer.php file is:

<?php # defining variables use in text acquire: $storename = "candy"; $customername = "william"; $storeaddress = "123 store street";  # text domain: $curl = curl_init(); curl_setopt($curl, curlopt_url, "https://somedomain.com/file.txt"); curl_setopt($curl, curlopt_returntransfer, true); $result = curl_exec($curl);  echo "$result"; 

actual result:

welcome our $storename store, $customername

our store located @ $storeaddress in somewhere.

expected result:

welcome our candy store, william

our store located @ 123 store street in somewhere.

how php parse variables, not treat them text?

and without using functions eval() or without enabling remote include "allow_url_include" or without regex or without explode break text , re-merge...

your best option use str_replace in situation, this:

<?php  $storename = "candy"; $customername = "william"; $storeaddress = "123 store street";  $result = 'welcome our $storename store, $customername<br> our store located @ $storeaddress in somewhere.';  $result = str_replace(     array('$storename','$customername','$storeaddress'),     array($storename,$customername,$storeaddress),     $result );  echo $result;
