    ▪PHP 计算代码执行耗时的代码修正网上普遍错误       代码如下: $t1 = explode(' ', microtime()); // ... 执行代码 ... $t2 = explode(' ', microtime()); echo ($t2[1]-$t1[1]).'s '.($t2[0]-$t1[0]).'ms'; 其实稍微试一下, 就能发现这份代码有个严重的问题. 虽然 t2 得到的时间.........

    ▪PHP与C#分别格式化文件大小的代码       PHP 版: 代码如下: function format($size) { $sizetext = array(" B", " KB", " MB", " GB", " TB", " PB", " EB", " ZB", " YB"); return round($size/pow(1024,($i=floor(log($size,1024)))),2).$sizetext[$i]; } C# 版: 代码如下: public string form.........

    ▪PHP读取ACCESS数据到MYSQL的代码       代码如下: <?php header('ontent-Type:text/html;charset=GB2312');//避免输出乱码 $dbhost ="localhost"; $dbuser ="root"; $dbpassword = "123456"; $dbname = "139miaosha"; mysql_connect($dbhost,$dbuser,$dbpassword) or die("error!"); mysql_quer.........

代码如下:

$t1 = explode(' ', microtime());
// ... 执行代码 ...
$t2 = explode(' ', microtime());
echo ($t2[1]-$t1[1]).'s '.($t2[0]-$t1[0]).'ms';

代码如下:

$t1 = microtime(true);
// ... 执行代码 ...
$t2 = microtime(true);
echo '耗时'.round($t2-$t1,3).'秒';

代码如下:

function format($size)
{
$sizetext = array(" B", " KB", " MB", " GB", " TB", " PB", " EB", " ZB", " YB");
return round($size/pow(1024,($i=floor(log($size,1024)))),2).$sizetext[$i];
}

代码如下:

public string formatSize(long size)
{
if (size == 0) return "0";
string[] sizetext = new string[] { " B", " KB", " MB", " GB", " TB", " PB" };
int i = (int)Math.Floor(Math.Log(size, 1024));
return Math.Round(size / Math.Pow(1024, i), 2).ToString() + sizetext[i];
}

代码如下:

<?php
header('ontent-Type:text/html;charset=GB2312');//避免输出乱码
$dbhost ="localhost";
$dbuser ="root";
$dbpassword = "123456";
$dbname = "139miaosha";
mysql_connect($dbhost,$dbuser,$dbpassword) or die("error!");
mysql_query("set names 'gbk'");
