Re: Sorting output to be returned to a HTML page using PHP
Doug
Sorry if I am thick, but where does the sort write the data to?
I have been trying to get the script you sent me to work, with no joy.
I have 107 entries in my selection, but when I sort them my $info
ends up with no records.
I have printed the $a[sortfield][0] and the $b[sortfield][0] in the
various "if statements" and get nothing.
When I list $info after the sort I get 0=107 and 1 to 107 = array.
The code I am using is
<?php {
$ds=ldap_connect("localhost");
if ($ds)
$r=ldap_bind($ds);
$justthese = array ("sn", "givenname);
$sr=ldap_search($ds,"dc=xxx,dc=yy","sn=*");
$info=ldap_get-entries($ds,$sr);
print "no of records to be sorted =".$info["count"];
function EntryCompare(&$a,&$b)
{
$sortfield = "sn";
if (!is_array($a))
return -1;
elseif (!is_array($b))
return 1;
if($a[$sortfield][0]==$b[$sortfield][0])
{
return 0;
}
if($a[$sortfield]>$b[$sortfield])
{
return 1;
}
else
{
return -1;
}
}
usort($info,EntryCompare);
while (list($key,$value)=each ($info))
{ echo "$key: $value\n";}
print "no of records in the sorted file =".$info["count"];
for ($i=0, $i<$info["count"]; $i++)
{
echo statement
}
Thanks for your help so far
