smarttemplate_extension_size.php

这些都是我以前学习是用到的源码

<?php

	/**
	* SmartTemplate Extension
	* 大小转换KB MB G
	*/
	function smarttemplate_extension_size ( $param )
	{
		if($param < 1024) {
			$size = $param."KB";
		}elseif($param < 1048576) {
			$size = ($param/1024);
			if(!is_int($size)) {
				$size  = number_format(($param/1024),1)."MB";
			}else {
				$size .= "MB";
			}
		}else {
			$size = ($param/1024/1024);
			if(!is_int($size)) {
				$size  = number_format(($param/1024/1024),2)."G";
			}else {
				$size .= "G";
			}
		}
		Return $size;
		
	}
?>
