array (0 => array ( 59 => ‘1’, 17 => ‘1’, 23 => ‘2’, 35 => ‘3’, 36 => ‘1’, 40 => ‘4’,43 => ‘1,3,7’, 44 => ‘1,2,6,9’, 70 => ‘15345178810’, ), )
上面的数组如何转换成下面的
array (0 => array ( 59 => ‘1’, 17 => ‘1’, 23 => ‘2’, 35 => ‘3’, 36 => ‘1’, 40 => ‘4’, 43_1 => ‘1’,43_3 => ‘1’,43_7 => ‘1’, 44_1 => ‘1’,44_2 => ‘1’,44_6 => ‘1’,44_9 => ‘1’, 70 => ‘15345178810’, ), )
回复讨论(解决方案)
$a = array (0 => array ( 59 => '1', 17 => '1', 23 => '2', 35 => '3', 36 => '1', 40 => '4',43 => '1,3,7', 44 => '1,2,6,9', 70 => '15345178810', ), );$R = array();foreach($a[0] as $k=>$v) { if(strpos($v, ',') !== false) { foreach(explode(',', $v) as $i) $r["{$k}_$i"] = 1; }else $r[$k] = $v;}print_r(array($r));
Array( [0] =><mark>@本文来源gaodaimacom搞#代%码@网-</mark><strong>搞代gaodaima码</strong> Array ( [59] => 1 [17] => 1 [23] => 2 [35] => 3 [36] => 1 [40] => 4 [43_1] => 1 [43_3] => 1 [43_7] => 1 [44_1] => 1 [44_2] => 1 [44_6] => 1 [44_9] => 1 [70] => 15345178810 ))
$a = array (0 => array ( 59 => '1', 17 => '1', 23 => '2', 35 => '3', 36 => '1', 40 => '4',43 => '1,3,7', 44 => '1,2,6,9', 70 => '15345178810', ), );$R = array();foreach($a[0] as $k=>$v) { if(strpos($v, ',') !== false) { foreach(explode(',', $v) as $i) $r["{$k}_$i"] = 1; }else $r[$k] = $v;}print_r(array($r));
Array( [0] => Array ( [59] => 1 [17] => 1 [23] => 2 [35] => 3 [36] => 1 [40] => 4 [43_1] => 1 [43_3] => 1 [43_7] => 1 [44_1] => 1 [44_2] => 1 [44_6] => 1 [44_9] => 1 [70] => 15345178810 ))
如果$a数组$a = array (0 =>array（）1=>array()…..)有多个是不是改成
$R = array(); $h=0; foreach($arr[$h] as $k=>$v) { if(strpos($v, ',') !== false) { foreach(explode(',', $v) as $i) $r["{$k}_$i"] = 1; }else $r[$k] = $v; $h++; } print_r(array($r));
那需要再套一层循环
