I have tried to execute matlab code in Server in php to get back the result. The following code are my php code. The matlab code is successfully executed however I cannot get the similarityScore back.

However i got an empty text file. I cannot figure the problem.

$command = "matlab -nojvm -nodesktop -nodisplay -r\    "similarityScore=getSimilarityScore('".$musci_path."','./upload/test.jpg','".$photo_upload_path."');\"";
 $value=exec($command);echo $value;
 $fp = fopen("myText.txt","wb");
 fwrite($fp,$value);
 fclose($fp);
