关于数组取值的有关问题

关于数组取值的问题!

PHP code

//已知数组$info=array();//输出print_r($info);//结果Array(    [0] => Array        (            [name] => 8.gif            [md5] => b68d88dbdfc9d0af2e0bbd85a4ccd28f            [saveName] => 20120602080557_452.gif            [size] => 1            [type] => image/gif            [originalHeight] => 39            [originalWidth] => 31        )    [1] => Array        (            [name] => 9.gif            [md5] => 4988f85ebebf82f56d70eeaf39a67016            [saveName] => 20120602080557_776.gif            [size] => 2            [type] => image/gif            [originalHeight] => 39            [originalWidth] => 31        ))

PHP code

foreach($info as $value){foreach($value as $getValue){echo $getValue['saveName'];}}
[解决办法]
foreach($info as $v)  $temp[]=$v['saveName'];
print_r($temp);
[解决办法]
看来name是类似于唯一字段了，想取出来和name对应的savename字段。如果这样的话，需要接收你给的name字段值，当你用post表单提交的吧。

二维数组。一个foreach判断就够了

PHP code
$a=Array( Array (            'name' => '8.gif',            'md5' => 'b68d88dbdfc9d0af2e0bbd85a4ccd28f' ,            'saveName' => '20120602080557_452.gif',            'size' => 1       ,            'type' => 'image/gif'   ,            'originalHeight' => 39 ,            'originalWidth' => 31        ),Array(            'name' => '9.gif'      ,            'md5' => '4988f85ebebf82f56d70eeaf39a67016',            'saveName' => '20120602080557_776.gif'  ,            'size' => 2    ,            'type' => 'image/gif'  ,            'originalHeight' => 39 ,            'originalWidth' => 31 ,        ))   ;foreach ($a as $k=>$v) {if ($v['name']===$_POST['yourname']){//令$_POST['yourname']=‘8.gif’，将输出$v ['saveName']=20120602080557_452.gifecho '$v ['.'savename'.']='.$v ['saveName'] .'<br>'   ;  }  }    ?>
