XML;

  

$xml

 = simplexml_load_string(

$string

);

  

foreach

 (

$data

 

as

 

$d

) {

      

$xml

->addChild('Row'," ID=\" {$d['id']} \"  Name=\" {$d['name']}\" " );

  

}

  

return

}

 
调用时每个都加上大数循环操作,并记录时间
代码如下:
 

 

$loop

=10000;

  

$xml

='';

  

switch

(

$_GET

['id']){

   

case

 1:

     

$ts

=

$this

->microtime_float();

     

for

( 

$i

=0; 

$i

<

$loop

; 

$i

++)

      

$xml

=

$this

->directWriteXml(

$depdata

);

     

$te

=

$this

->microtime_float();

     

$t

=

$te

-

$ts

;

     

$this

->assign('times',

$t

);

     

$this

->assign('method','直接写');

     

break

;

   

case

 2:

     

$ts

=

$this

for
