PHP转换阵列关联数组

Question

如何转换数组

Array 
(
    [1] => a,b,c 
    [2] => x,y,z 
) 

到一个关联数组一样

Array 
(
    [a]=> b,c 
    [x]=> y,z 
) 

基本上要一个数组的值转换成键。

Answer 1

试试这个，

$newArray = array(); 
foreach($array as $data){ 
    $values = explode(",",$data); 
    $key = array_shift($values); 
    $newArray[$key] = implode($values,","); 
} 
print_r($newArray); 

DEMO。

Answer 2

尝试像

$res = array(); 
foreach($my_arr as $value) 
{ 
    $my_var[] = explode(',',$value); 
    $i = 0; 
    foreach($my_var as $ky) 
    { 
     if($i++ != 0) 
     $exp_arr[] = $ky; 
    } 
    $res[$my_var[0]] = implode(',',$exp_arr); 
} 

，或者你可以不设置像

foreach($my_arr as $value) 
{ 
    $my_var[] = explode(',',$value); 
    $temp = $my_var[0]; 
    unset($my_var[0]); 
    $res[$temp] = implode(',',$my_var); 
} 

Answer 3

这样做：

$myArray=array(1=>'a,b,c', 2=>x,y,z); 
foreach($myArray as $val){ 
    $Xval=explode(",",$val); 
    $newKey=$Xval[0]; 
    unset($Xval[0]); 
    $newArray[$newKey]=implode(",",$Xval); 
} 

Answer 4

如何：

$arr = array('a,b,c','x,y,z'); 

$newArr = array(); 


foreach($arr as $key => $value) { 

    $value = explode(",",$value); 
    $firstValue = $value[0]; 
    array_shift($value); 
    $newArr[$firstValue] = implode(",",$value); 

} 

print_r($newArr); //Array ([a] => b,c [x] => y,z) 

Answer 5

试试这个

<?php 
$array=array('a,b,c', 'x,y,z'); 
foreach($array as $key=>$val) 
{ 
    $array[substr($val,0,1)]=substr($val,2); 
    unset($array[$key]); 
} 

print_r($array); 
?> 

See Demo

Answer 6

一个更快的解决方案：

foreach($array as $item){ 
    $x = explode(',',$item); 
    $new_array[$x[0]] = implode(','array($x[1],$x[2])); 
} 
print_r($new_array);
