How to save php code to php file_PHP tutorial

Many times we need to save the PHP code generated by PHP into the PHP file. For example, if the cache is used, some basic data will be directly saved to a specified PHP cache file. Let's take a look at an example.

代码如下

复制代码

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]=$str; } ob_clean(); ob_start(); echo " function echoArr($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; } ?>

Example

The code is as follows  代码如下 复制代码 //存储数组 $hello=array(1=>'test',2=>array('hello123')); cacheArr($hello); unset($hello); //读取数组 require 'hello.arr.php'; print_r($hello); ?>	Copy code

//Storage array
$hello=array(1=>'test',2=>array('hello123'));
cacheArr($hello);
unset($hello);
//Read array
require 'hello.arr.php';
print_r($hello);
?>
