Execute program in shell script using php

Question

I'm trying to automatise some Unity3D process to can call this from a PHP script.

I've already create an shell script that call some UNITY command line to create a project and for execute methods and if I use it in the terminal, works fine. The problem is when I use it into a PHP script: - I'm using shell_exec command to execute my script and all shell methods works (ls, mkdir, echo) but when I call to application nothing happend.

I was reading that is a permission problem into apache but after some hours I still without find a solution so.

I've mounted a server in my mac (Sierra) enabling apache and PHP 5 to test.

Regards, Gabriel

EDIT 1
I add here my code

This is my shell_script that works fine if i execute it in a terminal.

#!/bin/bash

UNITY_EXEC=/Applications/Unity_5.6.1f1/Unity.app/Contents/MacOS/Unity

if [ -z "$2" ]; then echo "You must provide a path to the bundle assets and a path to the resulting bundle."; exit 1; fi

export UNITY_ASSET_BUNDLE_PATH=${2}

CREATION_TIME=`date +%s` 
ASSET_BUNDLE_PROJECT_DIR=/tmp/AssetBundle-${CREATION_TIME}

echo "Creating temporary project."; 
${UNITY_EXEC} -batchmode -quit -createProject ${ASSET_BUNDLE_PROJECT_DIR};

echo "Copying resources from source folder to assets folder.";
cd $1; cp -r . ${ASSET_BUNDLE_PROJECT_DIR}/Assets;

echo "Finding assets."; 
cd ${ASSET_BUNDLE_PROJECT_DIR}; 
ASSETS_TO_BUNDLE=`find Assets -type f -not -name *.meta -not -name .DS_Store -not -name AssetsBundler.cs | sed 's/^.\///g' | sed 's/^/assetPathsList.Add("/g' | sed 's/$/");/g'`

mkdir ${ASSET_BUNDLE_PROJECT_DIR}/Assets/Editor/;
cat << EOT >> ${ASSET_BUNDLE_PROJECT_DIR}/Assets/Editor/AssetsBundler.cs
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEditor;

public class AssetsBundler{
    public static void Bundle(){
        List<string> assetPathsList = new List<string>();
        ${ASSETS_TO_BUNDLE}
        ArrayList assetList = new ArrayList();
        foreach(string assetPath in assetPathsList)
        {
            UnityEngine.Object[] assets = AssetDatabase.LoadAllAssetsAtPath(assetPath);
            foreach(UnityEngine.Object asset in assets)
            {
                assetList.Add(asset);
            }
        }
        UnityEngine.Object[] allAssets = (UnityEngine.Object[]) assetList.ToArray(typeof(UnityEngine.Object));

        BuildPipeline.BuildAssetBundle(allAssets[0], allAssets, "${UNITY_ASSET_BUNDLE_PATH}", BuildAssetBundleOptions.CollectDependencies | BuildAssetBundleOptions.CompleteAssets, BuildTarget.Android);
    }
}

EOT

echo "Building the bundle."; 
${UNITY_EXEC} -batchmode -quit -projectProject ${ASSET_BUNDLE_PROJECT_DIR} -executeMethod AssetsBundler.Bundle;

And this is my PHP_script

<?php

$old_path = getcwd();
chdir('./AssetBundleBuilder/');
$output = shell_exec('./AssetBundleBuilder ./Bundlify ./result.unity3d');
chdir($old_path);

echo $output;

?>

If i execute my PHP script from firefox, i receive as output all echo messages so thats tell me that the script is working. The thing is that the UNITY calls doesn't works.

Show some code friend.

I'll response my self.

Finally i got a solution using sockets. I've created a server socket in python to call the bash script in every connection and my client socket is in php that is the file that i call from a browser.

Thanks! Gabriel
