中的键来拉出其中的一些值
对php来说很新鲜。如果有人能提供使用php映射数组值的指导我将不胜感激这是var_dump
的输出array(3) {
["k"]=>
string(78) "method,from_tag,to_tag,callid,sip_code,sip_reason,time,from_user,to_user,token"
["v"]=>
string(326) "BYE,gFNk8BZBg,B2B.269.327,KjmE8oPOV1,200,OK,Wed May 28 23:11:43 2014
,patientdemo1.gmail,sip:join.me@192.168.1.20:5060;transport=udp,037d30d7239a0a16a658474822c3c9acf7995ac781a9c1c8b4b1a7361f24400d71216209c18eff8b8b0400bb55890bb2a78eb3064b603e6ac4e270b76c36be0e365bf096e426cfb6621aac13fdec54e7bbce74b3d63244b4cb622b16e27da1c4"
["query_type"]=>
string(6) "insert"
}
你可能已经注意到列键在第一个数组中键为"k"值在"v"下
我需要通过引用"k"
如评论所述。您可以使用 explode() 将keys和values分别设置为它们的数组。
如下所示:
<?php
$things = array(
'k' => 'method,from_tag,to_tag,callid,sip_code,sip_reason,time,from_user,to_user,token',
'v' => 'BYE,gFNk8BZBg,B2B.269.327,KjmE8oPOV1,200,OK,Wed May 28 23:11:43 2014
,patientdemo1.gmail,sip:join.me@192.168.1.20:5060;transport=udp,037d30d7239a0a16a658474822c3c9acf7995ac781a9c1c8b4b1a7361f24400d71216209c18eff8b8b0400bb55890bb2a78eb3064b603e6ac4e270b76c36be0e365bf096e426cfb6621aac13fdec54e7bbce74b3d63244b4cb622b16e27da1c4'
);
$keys = explode(',', $things['k']);
$values = explode(',', $things['v']);
?>
返回:
<键/strong>
Array
(
[0] => method
[1] => from_tag
[2] => to_tag
[3] => callid
[4] => sip_code
[5] => sip_reason
[6] => time
[7] => from_user
[8] => to_user
[9] => token
)
Array
(
[0] => BYE
[1] => gFNk8BZBg
[2] => B2B.269.327
[3] => KjmE8oPOV1
[4] => 200
[5] => OK
[6] => Wed May 28 23:11:43 2014
[7] => patientdemo1.gmail
[8] => sip:join.me@192.168.1.20:5060;transport=udp
[9] => 037d30d7239a0a16a658474822c3c9acf7995ac781a9c1c8b4b1a7361f24400d71216209c18eff8b8b0400bb55890bb2a78eb3064b603e6ac4e270b76c36be0e365bf096e426cfb6621aac13fdec54e7bbce74b3d63244b4cb622b16e27da1c4
)
现在只需要使用foreach():
$data = array();
foreach($keys as $i => $key) {
$data[$key] = $values[$i];
}
这将产生您的最终输出:
Array
(
[method] => BYE
[from_tag] => gFNk8BZBg
[to_tag] => B2B.269.327
[callid] => KjmE8oPOV1
[sip_code] => 200
[sip_reason] => OK
[time] => Wed May 28 23:11:43 2014
[from_user] => patientdemo1.gmail
[to_user] => sip:join.me@192.168.1.20:5060;transport=udp
[token] => 037d30d7239a0a16a658474822c3c9acf7995ac781a9c1c8b4b1a7361f24400d71216209c18eff8b8b0400bb55890bb2a78eb3064b603e6ac4e270b76c36be0e365bf096e426cfb6621aac13fdec54e7bbce74b3d63244b4cb622b16e27da1c4

这可能不是处理/做你想做的事情的最有效的方法。您应该重新考虑如何创建包含列/值的第一个数组，并对其进行重构以满足您的需求。
使用 array_combine() 相反!
