smarttemplate_extension_trunsize.php

这些都是我以前学习是用到的源码

<?php

	/**
	* SmartTemplate Extension
	* 大小转换字节 KB MB G
	*/
	function smarttemplate_extension_trunsize ( $param )
	{
		if($param < 1024) {
			$size = $param."字节";
		}elseif($param < 1048576) {
			$size = number_format($param/1024,1)."KB";
		}elseif($param < 1073741824) {
			$size = ($param/1048576);
			if(!is_int($size)) {
				$size  = number_format($size,1)."MB";
			}else {
				$size .= "MB";
			}
		}else {
			$size = ($param/1073741824);
			if(!is_int($size)) {
				$size  = number_format($size,2)."G";
			}else {
				$size .= "G";
			}
		}
		Return $size;
		
	}
?>
