把php代码保存到php文件实现方法

<?php
function cacheArr(&$data){
if(!$data)throw new Exception('数组不能为空');
foreach($GLOBALS as $key=>$value){
$str=$GLOBALS[$key];
$GLOBALS[$key]='changed';
if(&$data=='changed'){
$strName=$key;
break;
}
$GLOBALS[$key]=$str;
}
ob_clean();
ob_start();
echo "<?phpn";
function echoArr($arr,$arrName){
$arrCount=count($arr);$i==0;
foreach($arr as $key=>$value){
++$i;
if(is_array($value)){
echo "n".(is_numeric($key)?$key:'''.$key.''').'=>array(';
echoArr($value,$arrName.(is_numeric($key)?'['.$key.']':'[''.$key.'']'));
if($i!=$arrCount)echo '),';
else echo ')';
continue;
}
if($i!=$arrCount)echo ((is_numeric($key))?$key:'''.$key.''').'=>'.(is_numeric($value)？$value:'''.$value.''').',';
else echo ((is_numeric($key))?$key:'''.$key.''').'=>'.(is_numeric($value)?$value:'''.$value.''');
}
}
echo '$'.$strName.'=array(';
echoArr($data,'');
echo ');';
echo "n?>";
$file=fopen($strName.'.arr.php','w');
fwrite($file,ob_get_contents());
fclose($file);
ob_clean();
return true;
}
?>
测试
?
<?php
//存储数组
$hello=array(1=>'test',2=>array('http://www.hzhuti.com'));
cacheArr($hello);
unset($hello);
//读取数组
require 'hello.arr.php';
print_r($hello);
?>
