php is the implementation code for storing an array in a file

Share the code for the first time; It's badly written.. Tension, tension, tension)
php's 10-point array is powerful, and some data is not stored in the database and written directly to the file, but require when used.
(it's actually useful for storing an array in a file, but the Shared code is a little different from the actual application.)

 
<?php 
function cacheArr(&$data){ 
if(!$data)throw new Exception(' The array cannot be empty '); 
foreach($GLOBALS as $key=>$value){ 
$str=$GLOBALS[$key]; 
$GLOBALS[$key]='changed'; 
if($data=='changed'){ 
$strName=$key; 
break; 
} 
$GLOBALS[$key]=$str; 
} 
ob_clean(); 
ob_start(); 
echo "<?php\n"; 
function echoArr($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; 
} 
?> 
<?php 
// The storage arrays  
$hello=array(1=>'test',2=>array('hello123')); 
cacheArr($hello); 
unset($hello); 
// Reads an array of  
require 'hello.arr.php'; 
print_r($hello); 
?>
