Question

这是从数组输出。

[25.1] => Super Cylinder|2080
[25.2] => Main Post Powered Rotation|10780
[36.1] => Electric H-Frame Trolley|16630
[36.2] => Air Powered H-Frame Trolley|11028

我想要这样的输出如何获得此输出。如何将关联的键值设置为将成为圆数的主键。

[25]=> Super Cylinder|2080,Main Post Powered Rotation|10780
[36]= > Electric H-Frame Trolley|16630, Air Powered H-Frame

我如何获得这样的数组值。

Answer 1

使用常规foreach循环的简短解决方案：

$arr = [
    "25.1" => "Super Cylinder|2080",
    "25.2" => "Main Post Powered Rotation|10780",
    "36.1" => "Electric H-Frame Trolley|16630",
    "36.2" => "Air Powered H-Frame Trolley|11028"
];

$result = [];
foreach ($arr as $k => $v) {
    $rounded = round((int) $k);
    (isset($result[$rounded]))? $result[$rounded] .= ', '. $v : $result[$rounded] = $v;
}

print_r($result);

输出：

Array
(
    [25] => Super Cylinder|2080, Main Post Powered Rotation|10780
    [36] => Electric H-Frame Trolley|16630, Air Powered H-Frame Trolley|11028
)

Answer 2

您可以手动合并为：

<?php

$arr = array(
    "25.1" => "Super Cylinder|2080",
    "25.2" => "Main Post Powered Rotation|10780",
    "36.1" => "Electric H-Frame Trolley|16630",
    "36.2" => "Air Powered H-Frame Trolley|11028"
);

$ret = array();
foreach($arr as $key => $val){
    $key_new = intval($key);
    if(!isset($ret[$key_new])) $ret[$key_new] = array();
    array_push($ret[$key_new], $val);
}
//print_r($ret);

//merge the values
foreach($ret as $key => &$val){
    $val = implode(",", $val);
}
unset($val);
print_r($ret);

?>

这给出了：

Array
(
    [25] => Super Cylinder|2080,Main Post Powered Rotation|10780
    [36] => Electric H-Frame Trolley|16630,Air Powered H-Frame Trolley|11028
)

在php关联数组中需要帮助来替换键和值
