Looping for string comparison

Looping for string comparison

I developed code to search for - and / and then compare and arrange them.
Unfortunatly, it only works for two strings to compare and if more than
two strings compared by loop, it gives redundant data.
for($x=1, $y = 2; $x<$arrlength, $y<$arrlength; $x++, $y++) {
switch ($sort[$x])
{
case (strncasecmp($sort[$x],$sort[$y],strpos($sort[$x],'-')) == 0):
if
(substr(substr($sort[$x],0,strpos($sort[$y],'/')),0,strpos($sort[$y],'-'))
== false ){
echo " <TH class=\"tr1 td26\"><table><caption><P class=\"p16
ft4\">".substr($sort[$y],0,strpos($sort[$x],'-'))."</P></caption></table>";
echo "<P class=\"p12
ft4\">".ltrim(substr($sort[$x],strpos($sort[$x],'-')),"-")."</p></TH>";
echo " <TH class=\"tr1 td26\"><P class=\"p12
ft4\">".ltrim(substr($sort[$y],strpos($sort[$y],'-')),"-")."</P></TH>";
}
else {
echo " <TH class=\"tr1 td26\">";
echo " <table><caption><u><P class=\"p16
ft4\">".rtrim(rtrim((ltrim(substr(substr($sort[$x],strpos(strpos($sort[$x],'-'),'/')),strpos($sort[$x],'/')),"/")),ltrim(substr($sort[$x],strpos($sort[$x],'-')),"-")),"-")."</p><u></caption></table>";
echo "<P class=\"p12
ft4\">".ltrim(substr($sort[$x],strpos($sort[$x],'-')),"-")."</p></TH>";
echo " <TH class=\"tr1 td26\"><P class=\"p12
ft4\">".ltrim(substr($sort[$y],strpos($sort[$y],'-')),"-")."</P></TH>";
}
break;
case (strncasecmp($sort[$x],$sort[$y],strpos($sort[$x],'-')) <= 0):
echo " <TH class=\"tr1 td26\"><P class=\"p12
ft4\">".$sort[$x]."</P></TH>";
break;
case ((strncasecmp($sort[$x],$sort[$y],strpos($sort[$x],'/')) == 0) &&
(substr(substr($sort[$y],0,strpos($sort[$y],'/')),0,strpos($sort[$y],'-'))
!== false )) :
echo " <P class=\"p17
ft4\">".substr($sort[$y],0,strpos($sort[$x],'/'))."</P>";
break;
}
}
