直接返回数组的方法是最慢的
缓存文件,大家用的最多的估计就是 return array(); 实验证明,这种方法是较慢的,试考查以下的3个文件. 其一. $arr.php 直接返回 数组 return Array 其二, ini.php 为INI文件 return 分别对3个文件 进行10000次包含返回数组测试 $t1 = microtime(true); $file1 = ./arr.php; for($i=0; $i//$arr = require $file1; $t2 = microtime(true); 得出结果: arr.php 5.7820551395416 ini.php 5.3364160060883 str.php 5.5691919326782 其中,排得最快的居然是 INI文件. 其次是序列化, 最慢的是直接 return 数组 结论: ini 文件不错,方便书写(可以考虑) 保存数组, 用序列化!

其三,str.php 为序例化后的数组

?>
$file2 = ./ini.php;
$file3 = ./str.php;
//$arr = parse_ini_file($file2);
$arr = unserialize(require $file3);
}
echo $t2-$t1;
