Question

I have got the following, but in the results is a long string, contained within that string is a server name which I am wanting to sort the results by, is this possible?
<?php
$dbQuery = mysql_query("SELECT * FROM opencall where cust_id = 'user.name#jpress' and status < 6 order by fixbyx asc") or die(mysql_error());//find call ref of open call with correct id
while ($PRTGdbresults = mysql_fetch_array($dbQuery)){
$SplitText = explode("\n", $probtext); //split the string by line break
echo'<div class="row">';
echo'<div class="inf_div" title="Current Server">';
echo $SplitText[1]; //this is the server name I wish to sort by
echo'</div></div>';
}
?>

You can define your own function for sorting and then use this function with the usort sorting function.
Using the code you gave I will simply compare the strings of the server names and sort them in alphabetical order. Here is the code;
<?php
$dbQuery = mysql_query("SELECT * FROM opencall where cust_id = 'user.name#jpress' and status < 6 order by fixbyx asc") or die(mysql_error());
$results = array();
while ($PRTGdbresults = mysql_fetch_array($dbQuery)){
array_push($results,$probtext);
}
usort($results, "sortProbtext");
foreach($results as $key => $probtext){
$SplitText = explode("\n", $probtext);
echo'<div class="row">';
echo'<div class="inf_div" title="Current Server">';
echo $SplitText[1];
echo'</div></div>';
}
function sortProbtext($a, $b){
$SplitTextA = explode("\n", $a);
$SplitTextB = explode("\n", $b);
if ($SplitTextA[1] == $SplitTextB[1] ) {
return 0;
}
return ($SplitTextA[1] < $SplitTextB[1] ) ? -1 : 1;
}
?>
