Preg_grep find a partial match in a array of strings then compare to the original and display the output

curmudgeonly-grump · September 17, 2014

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>

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>';

Essentially this is the code that I am having issue with the rest is just for further reference. Output displays correctly and with the intended result coming from powershell thischanges based on the inputted CSV file . So it will display a mixture of "$destination is reachable on port $port using $protocol" and "$destination is not reachable on port $port using $protocol". So the keyword I am trying to search for with preg_grep is "not" and another preg_grep variable with "not" but inverted. Any reasons why the code below doesn't work? Thanks.

echo '<pre>';

$target="D:/Web/Upload/"; $target= $target . basename( $_FILES['uploaded']['name']) ;

$csv = $target;

//$filename= $_FILES['uploaded']['name'];

$output=shell_exec("powershell -Command D:/Web/scripts/PHPfwrules.ps1 $csv < NUL");

echo '<h6>';

print_r($output);

$nomatch=preg_grep('/^not/i',$output);

echo $nomatch;

$match=preg_grep("/not/",$output,PREG_GREP_INVERT);

echo $match;

if ($working1= array_intersect($output,$match))

{

echo"<link rel=stylesheet type=text/css href=style.css>

<tr>

<th>Server Name</th>

<th>Working</th>

</tr>

<tr>

<td>".$servername."</td>

<td>".$working1."</td>

</tr></table>

";

}

else if ($notworking1= array_intersect($output,$nomatch))

{

echo"<link rel=stylesheet type=text/css href=style.css>

<tr>

<th>Server Name</th>

<th>Not Working</th>

</tr>

<tr>

<td>".$servername."</td>

<td>".$notworking1."</td>

</tr></table>

";

}

Using $notworking = preg_match_all("/not/i", $output, $match, PREG_SET_ORDER); I am able to return the result "not" in a array. How do I get it to return the whole string this match was contained in or the indexed position of the element.
