php把數組儲存成檔案格式

標籤：

php把數組儲存為檔案格式的函數執行個體，或許有的還沒聽說過可以把數組儲存成檔案，其實這樣做也是另有它用的，兩種方法各有千秋，有興趣的PHP愛好者敬請參閱：

$file="./cache/file.cache";//定義要儲存的數組檔案路徑、名稱 $array = array("color" => array("blue", "red", "green"), "size" => array("small", "medium", "large")); file_put_contents($file,serialize($array));//寫入緩衝 //讀取緩衝 $handle = fopen($file, "r"); $cacheArray = unserialize(fread($handle, filesize ($file)));

下面是第二種方法，儲存較麻煩，但調用很省事：

function cache_write($name, $var, $values) {     $cachefile = S_ROOT.‘./data/data_‘.$name.‘.php‘;     $cachetext = "<?php\r\n".     "if(!defined(‘CHECK_CODE‘)) exit(‘Access Denied‘);\r\n".     ‘$‘.$var.‘=‘.arrayeval($values).     "\r\n?>";     if(!swritefile($cachefile, $cachetext)) {         exit("File: $cachefile write error.");     } } //數群組轉換成字串 function arrayeval($array, $level = 0) {     $space = ‘‘;     for($i = 0; $i <= $level; $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 $evaluate; } //寫入檔案 function swritefile($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;     } }

複製以上代碼為：data_cache.php檔案，使用時include：

@include (‘data_cache.php‘); //數組重新排序 sort($arrayName); 

調用方法：

cache_write(‘file‘,‘arrayName‘,$array);
