如何在现有数组中追加数据而不覆盖整个数组 [英] how to append data in existing array without overwrite whole array
问题描述
这是我的代码,在此代码中,我正在通过read_from_json函数读取现有数组,将JSON转换为数组,现在是从远程数据中获取新数据,因此我必须将这些数据附加到我现有的数组中,而不要覆盖整个数组。就像我得到一个ID一样,它使用in_array函数进行搜索,如果找不到它,则向其发送消息,然后将唯一的特定条目附加到现有数组中。由于foreach迭代存在问题,因此它会覆盖所有数组,我还能做什么。请看下面的代码:
This is my code, in this code, I am reading an existing array through a function read_from_json, which convert JSON to array, now from remote data I am getting new data so I have to append those data in my existing array without overwriting the whole array. Like if I am getting an id, it searches using the in_array function, if it is not found then sending a message to it, and then append the only specific entry to existing array. There is a problem due to foreach iteration so it overwrites all array, what else can I do. Please have a look at this code:
$read_data = $this->read_from_json( 'xyz.json' );
foreach ( $projects_id_tickcamp as $tick_id => $base_id ) {
if ( !$this->in_array( $base_id['base_id'], $read_data ) ) {
echo '<b>do post message function for ' . $tick_id . ' ' . $base_id['base_id'] . '</b><br />';
$i = count( $read_data );
while ( $i >= count( $base_id['base_id'] ) ) {
echo 'post message start' .'<br />';
$i++;
break;
$projects_id_tickcamp[$tick_id]['message_id'] = 1;
}
//echo 'posted message id of ' . $base_id['basecamp_id'] . '<br />';
} else {
echo 'do nothing' . '<br />';
//return false;
}
}
//echo 'write data if id similar' . '<br />';
$this->write_to_json( 'xyz.json', $projects_id_tickcamp );
return $projects_id_tick;
以上代码的输出如下:
Array
(
[125434] => Array
(
[base_id] => 1306755
)
[127354] => Array
(
[base_id] => 1287834
)
)
如果从远程获取新的id,则id仅写在数组的最后一个位置。
if a new id fetch from remote then id writes only in last place of array.
推荐答案
您有一些选择:
- array_push()
- array_merge($ curr_array,$ new_array)
- $ array [] = $ newValue
