<?php

$batfile = fopen("CNC/$wrtID/$wrtID.bat", "w") or die("Unable to open file!");
$txt = "
@ECHO OFF
@ECHO **** Run NC-Generator WOODWOP 4.0 ****
NCWEEKE.exe -n=C:/WW4/$wrtID/$wrtID-sl.mpr
NCWEEKE.exe -n=C:/WW4/$wrtID/$wrtID-sr.mpr
NCWEEKE.exe -n=C:/WW4/$wrtID/$wrtID-tb.mpr
NCWEEKE.exe -n=C:/WW4/$wrtID/$wrtID-dc.mpr

include("defaultcnc.php");

if ( additional file pats needed ) {
    include("component-1.php");
}

";

fwrite($slfile, $txt);
fclose($slfile);
?>

Answer 1

I don't see a problem in the first block of code.

On the second block, the interpreter will consider the second double quotes to mean the end of the string $txt = " include(". So everything after that would produce a PHP error.

But even if you escape those the mpr file will have the string include("defaultcnc,php"); but not the actual contents of that file. For that you should do file_get_contents("defaultcnc.php").

something like:

<?php
$slfile = fopen("CNC/$wrtID/$wrtID-sl.mpr", "w") or die("Unable to open file!");
// set params to pass to defaultcnc.php
$value1 = 1;
$value2 = "I'm a text string";
$file = urlencode("defaultcnc.php?key1=".$value1."&key2=".$value2);
$txt = file_get_contents($file);

if ( additional file pats needed ) {
    $txt .= file_get_contents("component-1.php");
}

fwrite($slfile, $txt);
fclose($slfile);
?>

I assume additional file pats needed means something to you. It should be a condition evaluating either true or false.
