[FX.php List] PHP Question

[DC]

steve,

i think there is a flaw in the example you gave... wouldn't the code 
posted result in an unclosed row if the mod value (column count) was not 
a factor of the array count?

here's a little general function set i put together that will close rows 
properly - i think it could still be improved however with the addition 
of the ability to add missing cells if the number of cells does not fill 
the last row. (exercise for the reader i guess.)

this wraps up variable column number table making into one tidy little 
function:

<?php
// shows how to make a generic
// variable column table maker

// dummy table data array akin to calendar
$t = range(1, 30);
// change this to change number of cols
$x = 7;
// that's it, call the function
print_r(make_x_column_table($t,$x));

// iterate over an array generate table
// with variable number of columns
function make_x_column_table($t,$x) {
	$cols = '';
	$table = '';
	$c = count($t)-1;
	// loop relies on zero indexed
	// keys to determine table close
	// here we force zero index keys
	$t = array_values($t);
	foreach ($t as $key => $data) {
		// we wrap each data bit in a column
		if ($c>=$key) {$cols .= column($data);}
		// only wrap the mod value in a row or the last row
		if (($key % $x)+1 === $x OR $c==$key) {
			// add on the row
			$table .= row($cols);
			// erase the cols
			$cols = '';
		}
	}
	// at end of array wrap in table
	return table($table);
}

// customize these to your liking
// they are here so HTML is sequestered from PHP
function column($s) {return '<td>'.$s.'</td>';}
function row($s) {return '<tr>'.$s.'</tr>';}
function table($s) {return '<table border="1" 
cellpadding="10">'.$s.'</table>';}
?>
