Hi I am trying to search an array that comes from a power shell script, the array of strings that returns is ever changing as it receives variables from the script. Therefore I need to use preg_grep to search for the word "not" I am also using another array which inverts this I then need to compare these new two arrays to the original and separate the results $working and not working into a table. I would be most grateful for any advice/solutions. The preg_grep aren't displaying anything. <?php //phpinfo(); ini_set('display_errors', 'On'); error_reporting(0);//E_ALL echo '<html> <style> body { font-family:Calibri,Helvetica,sans-serif; font-size:100%; } </style> <head> <link rel="stylesheet" type="text/css" href="style.css"> <script type="text/javascript"> function uploadJS(){ String.prototype.trim = function() { return this.replace(/^\s+|\s+$/g, ""); }; var textAreaValue=document.getElementById(\'ServerList\').value; var trimmedTextAreaValue=textAreaValue.trim(); if(trimmedTextAreaValue!="") { document.myForm.submit(); } else{ alert("Server List Text Area is Empty"); } }; var input=document.getElementById(\'fileSelect\').value; if(input!="") { document.myForm.submit(); } else{ alert("You have not selected a file, please select one to proceed."); } var handleFileSelect = function(e) { var files = e.target.files; if(files.length === 1) { document.forms.myForm.filecsv.value = files[0].name; } } }; </script> </head>'; #Upload Code $target = "D:\Web\Upload/"; $target = $target . basename( $_FILES['uploaded']['name']) ; $ok=1; if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target)) { echo "The file ". basename( $_FILES['uploadedfile']['name']).
