PHP數組值

Question

我有一個數組：

Array 
(
    [0] => hello;string1 
    [1] => bye;string2 
) 

我想要得到的陣列，所以我有字符串的值（後）是數組鍵的值，因此它成爲多維

Answer 1

$arr = array 
(
    "hello;string1", 
    "bye;string2" 
); 
$newArr = []; 
foreach ($arr as $a) { 
$e = explode(";", $a); 
    $newArr[$e[1]] = $e[0]; 
} 
print_r($newArr); 

Answer 2

你能做到這一點使用爆炸

的explode爆炸的變量上delimitter，你的情況; 它把內部數組中的分解值

<?php 
$arr = ['test;hi', 'another;one']; 
$newarr = []; 
foreach ($arr as $key => $value) { 

    $value = explode(';', $value); 
    $newarr[$value[0]] = $value[1]; 
} 
var_dump($newarr); 

輸出的var_dump：

array(2) { ["test"]=> string(2) "hi" ["another"]=> string(3) "one" } 

Answer 3

$array=Array 
(
    0 => "hello;string1", 
    1 => "bye;string2" 
); 
$result=array(); 
foreach($array as $data) 
{ 
    list($value,$key)=explode(";", $data); 
    $result[$key]=$value; 
} 
print_r($result); 

Answer 4

你應該使用這樣的事情！

$cars = array 
(
array("Volvo",22,18), 
array("BMW",15,13), 
array("Saab",5,2), 
array("Land Rover",17,15) 
); 

for ($row = 0; $row < 4; $row++) { 
echo "<p><b>Row number $row</b></p>"; 
echo "<ul>"; 
for ($col = 0; $col < 3; $col++) { 
echo "<li>".$cars[$row][$col]."</li>"; 
} 
    echo "</ul>"; 
} 

Outout

Row number 0 

Volvo 
22 
18 
Row number 1 

BMW 
15 
13 
Row number 2 


Saab 
5 
2 
Row number 3 

Land Rover 
17 
15

Answer 5

感謝您的幫助，這實際上是我想要的，對不起模糊

foreach ($arr as $a) { 
$e = explode(";", $a); 
$newarr[] = array('hello' => $e[0], 'bye' => $e[1]); 
}
