我使用过两种办法：
第一种是数组序列化，简单，但是调用时比较麻烦一些；第二种是保存为标准的数组格式，保存时麻烦但是调用时简单。
第一种方法：
PHP代码
代码如下:
$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)));
$array = array("color" => array("blue","red","green"),
"size" => array("small","medium","large"));
//缓存
file_put_contents($file,serialize($array));//写入缓存
//读出缓存
$handle = fopen($file,"r");
$cacheArray = unserialize(fread($handle,filesize ($file)));
第二种方法：
比较复杂，先贴几个函数：
代码如下:
//写入
function cache_write($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: $cachefile write error.");
}
}
//数组转换成字串
function arrayeval($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 $evaluate;
}
//写入文件
function swritefile($filename,$writetext,$openmod='w') {
if(@$fp = fopen($filename,$openmod)) {
flock($fp,2);
fwrite($fp,$writetext);
fclose($fp);
return true;
} else {
runlog('error',"File: $filename write error.");
return false;
}
}
function cache_write($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: $cachefile write error.");
}
}
//数组转换成字串
function arrayeval($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 $evaluate;
}
//写入文件
function swritefile($filename,$writetext,$openmod='w') {
if(@$fp = fopen($filename,$openmod)) {
flock($fp,2);
fwrite($fp,$writetext);
fclose($fp);
return true;
} else {
runlog('error',"File: $filename write error.");
return false;
}
}
调用方法很简单：
PHP代码
代码如下:
cache_write('file','arrayName',$array);
使用上形同标准的include格式：
PHP代码
代码如下:
