Unable to run shell script with full permissions (UNIX)

Question

I have a shell script that is created inside a PHP script (with full permissions). When I try to start a script shell from Terminal, I get no errors, but the script does not start (none of the commands are executed). Although, after copying the contents of the shell script, paste them into a new file in Xcode and overwrite the old shell script, it works correctly.

Any suggestions? I tried to figure this out for a very long time without any success.

I assume that there is a problem with writing a shell script from a PHP script, since it works when written in Xcode or a text editor.

Here is the php script that writes the shell script:

<code>
    $filePath = "/Applications/MAMP/htdocs/php/Batch/modulator/Release23/Library/irShell.sh";
    $script = fopen($filePath, 'w+');
    chmod($filePath, 0777);
    fwrite($script,"#!/bin/sh");
    $irPath = "/Applications/MAMP/htdocs/php/Batch/modulator/Release23/Library"; //path to .ir files
    $modPath = "/Applications/MAMP/htdocs/php/Batch/modulator";

    if($dir = opendir($irPath)){        
        while(($file = readdir($dir)) !== false){
            $posA = strpos($file, ".IR");
            $posB = strpos($file, ".ir");
            $posC = strpos($file, ".Ir");
            if ($posA == true){
                $fileName = trim($file, ".IR");
                $noT = substr_replace($fileName, "", 0, 1);
                echo "$noT\n";
                fwrite($script, "\r" . $modPath . "/mod -o " . $irPath . "/codes/" . $noT . " " . $fileName . ".IR"); 
            }
            else if ($posB == true){
                $fileName = trim($file, ".ir");
                $noT = substr_replace($fileName, "", 0, 1);
                echo "$noT\n";
                fwrite($script, "\r" . $modPath . "/mod -o " . $irPath . "/codes/" . $noT . " " . $fileName . ".ir");
            }
            else if ($posC == true){
                $fileName = trim($file, ".Ir");
                $noT = substr_replace($fileName, "", 0, 1);
                echo "$noT\n";
                fwrite($script, "\r" . $modPath . "./mod -o " . $irPath . "/codes/" . $noT . " " . $fileName . ".Ir");
            }
        }
    }
</code>

And here is an example shell script that is generated by this php:

#!/bin/sh

/Applications/MAMP/htdocs/php/Batch/modulator/mod -o /Applications/MAMP/htdocs/php/Batch/modulator/Release23/Library/codes/1294 T1294.ir
/Applications/MAMP/htdocs/php/Batch/modulator/mod -o /Applications/MAMP/htdocs/php/Batch/modulator/Release23/Library/codes/1295 T1295.ir
/Applications/MAMP/htdocs/php/Batch/modulator/mod -o /Applications/MAMP/htdocs/php/Batch/modulator/Release23/Library/codes/1296 T1296.ir

\r fwrite \n ( fwrite($script, "\n"); , ( fclose(), ).

fwrite($script,"#!/bin/sh" . "\n");
...
fwrite($script, $modPath . "/mod -o " . $irPath . "/codes/" . $noT . " " . $fileName . ".IR" . "\n");
...
fclose($script);

fwrite($script,"#!/bin/sh");
...
fwrite($script, "\n" . $modPath . "/mod -o " . $irPath . "/codes/" . $noT . " " . $fileName . ".IR" . "\n");
...
fwrite($script, "\n");
fclose($script);
