PHP 数组
Array
(
[0] => pid=2
[1] => action=save
[2] => 9=a
[3] => 10=a
[4] => 14=a
[5] => 20=a
[6] => 15=a
[7] => 15=b
[8] => 21=a
[9] => 21=b
[10] => 16=c
[11] => 16=d
[12] => 19=c
[13] => 19=d
[14] => 17=we
[15] => 22=keywork
[16] => 18=you
[17] => 23=thanks
)
上面数组，如何把它转成下面样子:
Array
(
[0] => pid=2
[1] => action=save
[2] => 9=a
[3] => 10=a
[4] => 14=a
[5] => 20=a
[6] => 15=ab
[7] => 21=ab
[8] => 16=cd
[9] => 19=cd
[10] => 17=we
[11] => 22=keywork
[12] => 18=you
[13] => 23=thanks
)
------解决方案--------------------
$a = array(
'pid=2',
'action=save',
'9=a',
'10=a',
'14=a',
'20=a',
'15=a',
'15=b',
'21=a',
'21=b',
'16=c',
'16=d',
'19=c',
'19=d',
'17=we',
'22=keywork',
'18=you',
'23=thanks',
);
foreach($a as $v) list($b[$v][],$v) = array_reverse(explode('=', $v));
array_walk($b, create_function('&$v,$k', '$v="$k=".join("",$v);'));
print_r(array_values($b)); Array
(
[0] => pid=2
[1] => action=save
[2] => 9=a
[3] => 10=a
[4] => 14=a
[5] => 20=a
[6] => 15=ab
[7] => 21=ab
[8] => 16=cd
[9] => 19=cd
[10] => 17=we
[11] => 22=keywork
[12] => 18=you
[13] => 23=thanks
)
