Php To Bash Script Help

Can someone help me make gen.sh from this php code?

<?
$total = 0; // Just for testing, can be removed
$file = "known.list";
$page = join("",file("$file"));
$kw = explode("\n", $page);
// Create known.out file with mac adresses from known.list
exec("$ > known.out");
for($i=0;$i<count($kw);$i++){
$total = $i+1;
exec("cat /tmp/dhcp.leases | grep $kw[$i] >> known.out");
}
// Create unknown.out file with all connected mac adresses excluding mac's from known.list
exec("cat /tmp/dhcp.leases > connected.list");
exec("cat connected.list > unknown.out");
for($i=0;$i<count($kw);$i++){
exec("sed -i '/$kw[$i]/d' unknown.out");
}
?>
[/CODE]

I solved my problem

#!/bin/bash
rows=0;
mac="xx:xx:xx:xx:xx"
file="known.list"
for f in known.list;
  do
    let rows+=`wc $f | awk '{print $1}'`
  done

# Use known.list to filter mac adresses from dhcp.leases
rm known.out
saveIFS="$IFS"
IFS=$'\n'
array=($(<$file))
IFS="$saveIFS"
for i in "${array[@]}"; do cat /tmp/dhcp.leases | grep $i >> known.out; done
# Create unknown.out
cat /tmp/dhcp.leases > connected.list
cat connected.list > unknown.out
saveIFS="$IFS"
IFS=$'\n'
array=($(<$file))
IFS="$saveIFS"
# echo ${array[0]}    # outputs first line
for i in "${array[@]}"; do sed -i '/'$i'/d' unknown.out; done
