$file=./cache/file.cache; $array = array(color => array(blue, red, green), size => array(small, medium, large)); //缓存 file_put_contents($file,serialize($array));//写入缓存 //读出缓存 $handle = fopen($file, r); $cachearray = unserialize(fread($handle, filesize ($file)));

第二种方法：
先贴几个函数：
//写入 function cache_write($name, $var, $values) { $cachefile = s_root.'./data/data_'.$name.'.php'; $cachetext = ; if(!swritefile($cachefile, $cachetext)) { exit(file: $cachefile write error.); } } //数组转换成字串 function arrayeval($array, $level = 0) { $space = ''; for($i = 0; $i $space .= \t; } $evaluate = array\n$space(\n; $comma = $space; foreach($array as $key => $val) { $key = is_string($key) ? '\''.addcslashes($key, '\'\\').'\'' : $key; $val = !is_array($val) && (!preg_match(/^\-?\d+$/, $val) || strlen($val) > 12) ? '\''.addcslashes($val, '\'\\').'\'' : $val; if(is_array($val)) { $evaluate .= $comma$key => .arrayeval($val, $level + 1); } else { $evaluate .= $comma$key => $val; } $comma = ,\n$space; } $evaluate .= \n$space); return $evaluate; } //写入文件 function swritefile($filename, $writetext, $openmod='w') { if(@$fp = fopen($filename, $openmod)) { flock($fp, 2); fwrite($fp, $writetext); fclose($fp); return true; } else { runlog('error', file: $filename write error.); return false; } }

调用：
cache_write('file', 'arrayname', $array); include格式：
@include ('./data/data_cache.php'); //数组重新排序 sort($arrayname);
