<?php
function size_format( $bytes, $decimals = null ) {
	$quant = array(
		// ========================= Origin ====
		'TB' => 1099511627776,  // pow( 1024, 4)
		'GB' => 1073741824,     // pow( 1024, 3)
		'MB' => 1048576,        // pow( 1024, 2)
		'kB' => 1024,           // pow( 1024, 1)
		'B ' => 1,              // pow( 1024, 0)
	);
 
	foreach ( $quant as $unit => $mag )
		if ( doubleval($bytes) >= $mag )
			return number_format_i18n( $bytes / $mag, $decimals ) . ' ' . $unit;
 
	return false;
}

Dump variables

April 28, 2011 | Comments | PHP

This is my extension of an existing function, adatped for my requirements.

?View Code PHP
<?php
function dumpr($VARIABLE_NAME, $DATA){
    if (is_object($DATA)) {
        $data = (array) $DATA;
    } elseif (is_array($DATA)) {
        $data = $DATA;
    } else {
        $data = strval($DATA);
    }
    $output = "<table class='dumpr'>";
    $output .= "<head>";
    $output .= "<tr>";
    $output .= "<th colspan='2'>" . $VARIABLE_NAME . "</th>";
    $output .= "</tr>";
    $output .= "</head><body>";
    if (is_array($data)){
        foreach ($data as $key => $value) {
            //$value = dumpr($key, $value);
            $output .= "<tr>";
            $output .= "<td>$key</td>";
            $output .= "<td>$value</td>";
            $output .= "</tr>";
        }
    } else {
        $output .= "<tr>";
        $output .= "<td colspan=2>$data</td>";
        $output .= "</tr>";
    }
    $output .= "</body>";
    $output .= "</table>";
    return $output;
}
?>

Use like this:
echo dumpr(‘NAME’,$var);
echo dumpr(‘SESSION’,$_SESSION);
etc..

Displays a nicely formatted table, with values of a string / array / object clearly displayed.

Compressing CSS files – on the fly

July 20, 2010 | Comments | PHP

I hate compressing CSS files as they become totally unreadable for editing. I end up keeping 2 versions, compressed and uncompressed, etc.. But how about compressing all your CSS files into one file, ‘on-the-fly’. Now that has solved the problem.
