尝试将混合字符串转换为数组但无法获得准确的输出

Question

您好，我正在尝试将混合字符串转换为数组，但无法获得准确的输出。

我已经使用 explode 函数删除管道符号，但我无法获得准确的输出

下面是我到目前为止尝试过的代码：

$customstring = "Eye Width=3/4 in|Finish=Nickel|Hook Opening=7/16 in|Locking Type=Spring Loaded Plunger|Material=Zinc Die Cast|Mounting=Swivel Eye|Overall Length [Nom]=3 1/2 in|Type=Swiveled Securing Hook|Wt.=0.09 lb";

echo "String :<br>".$customstring;
$testarray = explode("|",$customstring);

echo "ARRAY<br><pre>";
print_r($testarray);

我得到的输出如下：

Array
(
    [0] => Eye Width=3/4 in
    [1] => Finish=Nickel
    [2] => Hook Opening=7/16 in
    [3] => Locking Type=Spring Loaded Plunger
    [4] => Material=Zinc Die Cast
    [5] => Mounting=Swivel Eye
    [6] => Overall Length [Nom]=3 1/2 in
    [7] => Type=Swiveled Securing Hook
    [8] => Wt.=0.09 lb
)

但我想删除这个“=”等于并使左值为键，右值为值。在下面查看我的预期输出。

但我的预期输出是这样的：

Array
(
    [Eye Width] => 3/4 in
    [Finish] => Nickel
    [Hook Opening] => 7/16 in
    [Locking Type] => Spring Loaded Plunger
    [Material] => Zinc Die Cast
    [Mounting] => Swivel Eye
    [Overall Length [Nom]] => 3 1/2 in
    [Type] => Swiveled Securing Hook
    [Wt.] => 0.09 lb
)

非常感谢

Answer 1

我将遍历你的新数组并展开 = 字符上的每个项目。

foreach($testarray as $item){
    $arr = explode("=", $item);
    $testarray[$arr[0]] = $arr[1];
}

唯一的问题是您需要整理 $testarray 以删除数字键项。

为了解决这个问题，我只创建了一个最终数组

foreach($testarray as $item){
    $arr = explode("=", $item);
    $final[$arr[0]] = $arr[1];
}

<?php

$string = "Eye Width=3/4 in|Finish=Nickel|Hook Opening=7/16 in|Locking Type=Spring Loaded Plunger|Material=Zinc Die Cast|Mounting=Swivel Eye|Overall Length [Nom]=3 1/2 in|Type=Swiveled Securing Hook|Wt.=0.09 lb";

$formed_data = explode("|", $string);
$desired_data = [];
foreach ($formed_data as $single_string) {
    $words= explode("=", $single_string);
    $desired_data[$words[0]] = $words[1];
}
var_dump($desired_data);
/**
 * Output
 */
array(9) {
  ["Eye Width"]=>
  string(6) "3/4 in"
  ["Finish"]=>
  string(6) "Nickel"
  ["Hook Opening"]=>
  string(7) "7/16 in"
  ["Locking Type"]=>
  string(21) "Spring Loaded Plunger"
  ["Material"]=>
  string(13) "Zinc Die Cast"
  ["Mounting"]=>
  string(10) "Swivel Eye"
  ["Overall Length [Nom]"]=>
  string(8) "3 1/2 in"
  ["Type"]=>
  string(22) "Swiveled Securing Hook"
  ["Wt."]=>
  string(7) "0.09 lb"
}
[Finished in 0.0s]

通过使用 foreach 你可以获得想要的结果

连续显示的两种方法：

1) 使用额外的 explode 函数结合 list 函数：

$customstring = "Eye Width=3/4 in|Finish=Nickel|Hook Opening=7/16 in|Locking Type=Spring Loaded Plunger|Material=Zinc Die Cast|Mounting=Swivel Eye|Overall Length [Nom]=3 1/2 in|Type=Swiveled Securing Hook|Wt.=0.09 lb";

$pairs = explode("|", $customstring);
$result = [];
foreach ($pairs as $p) {
    list($k, $v) = explode('=', $p);
    $result[$k] = $v;
}

print_r($result);

2) 另一种替代解决方案是使用 preg_match_all 和 array_combine 函数：

$customstring = "Eye Width=3/4 in|Finish=Nickel|Hook Opening=7/16 in|Locking Type=Spring Loaded Plunger|Material=Zinc Die Cast|Mounting=Swivel Eye|Overall Length [Nom]=3 1/2 in|Type=Swiveled Securing Hook|Wt.=0.09 lb";
preg_match_all("/([^=|]+)=([^+|]+)/", $customstring, $m);
$result = array_combine($m[1], $m[2]);

print_r($result);

输出（两种方法相同）：

Array
(
    [Eye Width] => 3/4 in
    [Finish] => Nickel
    [Hook Opening] => 7/16 in
    [Locking Type] => Spring Loaded Plunger
    [Material] => Zinc Die Cast
    [Mounting] => Swivel Eye
    [Overall Length [Nom]] => 3 1/2 in
    [Type] => Swiveled Securing Hook
    [Wt.] => 0.09 lb
)

Answer 4

@Manthan Dave simply do with foreach with make a condition like below:

<?php
    $customstring = "Eye Width=3/4 in|Finish=Nickel|Hook Opening=7/16 in|Locking Type=Spring Loaded Plunger|Material=Zinc Die Cast|Mounting=Swivel Eye|Overall Length [Nom]=3 1/2 in|Type=Swiveled Securing Hook|Wt.=0.09 lb";
    echo "String :<br>".$customstring;
    $testarray = explode("|",$customstring);

    echo "ARRAY<br><pre>";
    print_r($testarray); // before
    foreach($testarray as $key => $val){
        if(strpos($val, "=") || strpos($val, "=") == "0"){
            $temp = explode("=", $val);
            $testarray[$key] = $temp[1];
        }
    }
    echo "ARRAY<br><pre>";
    print_r($testarray); // after
