I learnt coding using cobol and pascal, and the dataease dbms which was
pretty lovely to use.

To break out of the current itteration and start the next itteration use
'continue'.
To exit the loop completely use 'break'.

I'm not exactly sure what you need but:-
// Read all lines in the file into an array, one line per array element.
$lines = file('filename');
// Cycle through the array starting at the first element (first line in the
file)
// $line_num is the current array element/line number.
// $line is the contents of the array element
foreach ($lines as $line_num => $line) {
// Process until 32nd line
if (($line_num + 1) == 32) {
// Exit loop
break;
}
process $line...
}
OR:
$lines = file('filename');
for ($c = 1; $c < count($lines); $c++) {
if ($c == 32) {
break;
}
process $lines[$c]...
}
If you want to start a new table at record 32 try:
$lines = file('filename');
echo "<table>\n";
for ($c = 0; $c < count($lines); $c++) {
echo "<tr><td>".$lines[$c]."</td></tr>\n";
if ($c == 32) {
echo "</table>\n<table>"
}
}
Or every 32nd record:
$lines = file('filename');
echo "<table>\n";
for ($c = 0; $c < count($lines); $c++) {
echo "<tr><td>".$lines[$c]."</td></tr>\n";
// Use modulus to test if current line cleanly divides into 32
// I may have cocked this bit up as I haven't tested any
// of this code, but I'm sure you get the idea.
if (32 % $c) {
echo "</table>\n<table>"
}
}
