php数组
<br />.....<br /><br />$str=array();<br />foreach($strarray as $k=>$v){<br /> $one=$v['one'];<br /> $two=$v['two'];<br /> $tree=$v['tree'];<br /> <br /> }<br /><br />
如何用 $str保存成如下
$str=array('one'=>$v['one'],'two'=>$v['two'], 'tree'=>$v['tree'])
------解决思路----------------------$strarray是一个数组,$str是单个元素,不知道数组结构怎么映射成一个元素的
如果$str是多个元素的数组的话,可以这么写
$str=array();
foreach($strarray as $k=>$v){
$str[] = array(
'one' => $v['one'],
'two' => $v['two'],
'tree' => $v['tree'],
);
}
当然还有更简单的方法:
$str=array();
foreach($strarray as $k=>$v){
$str[] = array_intersect_key($v, array('one' => 1, 'two' => 1, 'tree' => 1));
}
还有不是tree,是three吧
------解决思路----------------------<br /><?php<br />$str=array();<br />$strarray = array(<br /> array('one'=>1,'two'=>2,'three'=>3),<br /> array('one'=>1,'two'=>2,'three'=>3),<br /> array('one'=>1,'two'=>2,'three'=>3),<br />);<br />foreach($strarray as $k=>$v){<br /> $str['one'][] = $v['one'];<br /> $str['two'][] = $v['two'];<br /> $str['three'][] = $v['three'];<br />}<br />print_r($str);<br />?><br />
