php 把数组保存为标准的数组格式，存储到文件中

 

<?php 
$file='./test.php'; 
$array=array('color'=> array('blue','red','green'),'size'=> array('small','medium','large')); 
cache_write($file,$array,'rows',false); 
  
//写入 
function cache_write($filename,$values,$var='rows',$format=false){ 
  $cachefile=$filename; 
  $cachetext="<?php\r\n".'$'.$var.'='.arrayeval($values,$format).";"; 
  return writefile($cachefile,$cachetext); 
} 
  
//数组转换成字串 
function arrayeval($array,$format=false,$level=0){ 
  $space=$line=''; 
  if(!$format){ 
    for($i=0;$i<=$level;$i++){ 
      $space.="\t"; 
    } 
    $line="\n"; 
  } 
  $evaluate='Array'.$line.$space.'('.$line; 
  $comma=$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,$format,$level+1); 
    }else{ 
      $evaluate.=$comma.$key.'=>'.$val; 
    } 
    $comma=','.$line.$space; 
  } 
  $evaluate.=$line.$space.')'; 
  return $evaluate; 
} 
  
//写入文件 
function writefile($filename,$writetext,$openmod='w'){ 
  if(false!==$fp=fopen($filename,$openmod)){ 
    flock($fp,2); 
    fwrite($fp,$writetext); 
    fclose($fp); 
    return true; 
  }else{ 
    return false; 
  } 
}
