我得到了以下内容，但是结果中是一个长字符串，该字符串中包含我想对结果进行排序的服务器名称，这可能吗？
<?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>';
}
?>
您可以
定义自己的排序函数，然后将此函数与usort排序函数一起使用。
使用您提供的代码，我将简单地比较服务器名称的字符串并按字母顺序对它们进行排序。这是代码;
<?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;
}
?>
