"--compact" :Produce less verbose output. This option enables the --skip-add-drop-table, --skip-add-locks, --skip-comments, --skip-disable-keys, and --skip-set-charset options.

PHP:取得变量名

源程序：

/* 取得变量的名字 */
function getVarName(&$src)
{
//存储当前变量值
$save = $src;
//存储所有变量值
$allvar = $GLOBALS;
//在函数中不要直拉遍历$GLOBALS,会出现堆栈问题
foreach($allvar as $k=>$v)
{
//变量值相同，可能不是相同变量,因多个变量的值可能相同
if ($src == $v)
{
//改变当前变量$src的值
$src = 'change';
//如果$GLOBALS[$k]也跟着改变，那就是同一个变量。
if ($src == $GLOBALS[$k])
{
echo "\$$k name is $k
";
}
}
}
//还原变量值
$src = $save;
}
$test = "helo";
$test2 = "helo";
getVarName($test);
?>

改进后：
function getVarName(&$src)
{

$save = $src;
$allvar = $GLOBALS;
foreach($allvar as $k=>$v)
{
if ($src == $v)
{
$src = 'change';
if ($src == $GLOBALS[$k] && $k != 'argc')
{
//echo "\$$k name is $k
";
$src = $save;
return $k;
}
}
}
$src = $save;
}

Prototype JS Event.observe

CODE:
/*
*you'd want this line of code to run once the form exists in the DOM; but putting *inline scripts in the document is pretty obtrusive, so instead we'll go for a simple *approach that waits till the page is fully loaded:
*/
Event.observe(window, 'load', function() {
Event.observe('percent', 'change', selectProPercent);
}

in main.js:
var selectProPercent = function()
