php delete file.pdf before packaging - php

Question

How do I go about deleting instructions.pdf from a temp directory?
My web script creates temporary folders with a unique id and requests some files from another server. One such file is "instructions.pdf". I want to delete this file before the temporary folder gets packaged into a zip file.
I think the easiest way would be to overwrite these files using some PHP code AFTER the package is downloaded from the API but before the package is zipped up for the user. Understanding the steps in the process may make this easier to conceptualize.
a) User click "package source code"
b) Self hosted panel contacts API
c) API returns a project package (containing the instructions.pdf) this is a zip archive
d) Self hosted panel unzips the archive for processing
e) Self hosted panel adds plugins and other assets and makes some adjustments to the package
f) Self hosted panel creates a zip archive in the /files/temp folder for the user to download.
This means that I would add an additional step before f). "Delete the instructions.pdf from the package and replace with "this file on my server" before creating the zip archive."
I want to add new logic approximately where it reads "process plugins". I need to do this in two places (same logic but a bit different for each platform) once for iOS and once for Android. Same file handles both packages.
I have tried unlink but it's not deleting anything. Here is the code I am using without success:
// delete pdf...
if($fh = fopen($rootFolder . "instructions.pdf", 'w')){
fclose($fh);
unlink('instructions.pdf');
}
the full php code is :
<?php require_once("../../config.php");
require_once("../../includes/zip.php");
//who's logged in
$guid = "";
if(isset($_SESSION[APP_LOGGEDIN_COOKIE_NAME])) $guid = fnFormInput($_SESSION[APP_LOGGEDIN_COOKIE_NAME]);
//init user object
$thisUser = new User($guid);
$thisUser -> fnLoggedInReq($guid);
$thisUser -> fnUpdateLastRequest($guid, "1");
//try to increase max execution time..This is only necessary on painfully slow servers!
if(!ini_get('safe_mode')){
#set_time_limit(120);
}
//project vars posted in AJAX request...
$appGuid = fnGetReqVal("appGuid", "", $myRequestVars);
$whatPlatform = fnGetReqVal("whatPlatform", "", $myRequestVars);
$saveToPath = "";
$packageURL = "";

$strMessage .= "<br>No app id found";

if(strlen($whatPlatform) < 1){
$bolPassed = false;
$strMessage .= "<br>There was a problem figuring out what platform to package the project for?";

Answer 1

You PHP code is too big for anyone here to read.
maybe you're doing it wrong from here:
// delete pdf...
if($fh = fopen($rootFolder . "instructions.pdf", 'w')){
fclose($fh);
unlink('instructions.pdf');
}
change it to (use file_exists as you don't need to read the file):
// delete pdf...
if(file_exists($rootFolder . "instructions.pdf"){
unlink($rootFolder . "instructions.pdf");
}
you should have permissions on that file.
