使用 for 循环将数据推入数组答案

【问题标题】：Push data into array with for loop使用 for 循环将数据推入数组

我需要像这样生成一个数组：

$person = array(
    array(
        "name" => "brian",
        "age" => "25"
    ),
    array(
         "name" => "simon",
         "age" => "21"
    )
);

我把这段代码放到一个简单的for循环中：

for ($x = 0; $x <= 10; $x++) {
    $new_array = array("name"=>'Brian', "age"=>'25');
    array_push($person, $new_array);
}

如果 for 循环必须重复 10 次，我应该有 10 行带有 Brian 姓名和 25 岁的行，但我有这个结果：

Array ( [1] => Array ( [name] => Brian [age] => 25 ) [value] => Array ( [name] => Brian [age] => 25 ) [0] => 0 [key] => 0 )

我对 array_push 做错了吗？谢谢

【解决方案1】：

创建$new_array = array();

for ($x = 0; $x <= 10; $x++) {
    $new_array[] = array("name"=>'Brian', "age"=>'25');   
}
print_r($new_array);

输出将是

Array ( [0] => Array ( [name] => Brian [age] => 25 ) 
    [1] => Array ( [name] => Brian [age] => 25 ) 
    [2] => Array ( [name] => Brian [age] => 25 ) 
    [3] => Array ( [name] => Brian [age] => 25 ) 
    [4] => Array ( [name] => Brian [age] => 25 ) 
    [5] => Array ( [name] => Brian [age] => 25 ) 
    [6] => Array ( [name] => Brian [age] => 25 ) 
    [7] => Array ( [name] => Brian [age] => 25 ) 
    [8] => Array ( [name] => Brian [age] => 25 ) 
    [9] => Array ( [name] => Brian [age] => 25 ) 
    [10] => Array ( [name] => Brian [age] => 25 ) 
)

【解决方案2】：

如果您已经将人员作为单个数组，array_push 可能对您很感兴趣，因为它允许您一步推送多个数组：

$brian = array(
                "name" => "brian",
                "age" => "25"
        );
$simon = array(
        "name" => "simon",
        "age" => "21"
);

$persons = [];
array_push($persons, $brian, $simon);
