在做APP接口的時(shí)候，返回的數(shù)據(jù)需要全部是
string類型仑撞，在返回?cái)?shù)據(jù)之前聋袋，可以使用這個(gè)函數(shù)
/** int類型轉(zhuǎn)換成string類型
* @param $arr
* @return array|string
*/
function intToStr($arr)
{
if (!is_array($arr)) {
return (string)$arr;
}
foreach ($arr as $key => $value) {
if (is_array($value)){
$arr[$key] = intToStr($value);
}else{
$arr[$key] = (string)$value;
}
}
return $arr;
}
- 將數(shù)組寫入文件
function get_team_arr()
{
global $le_db1;
$sql = "select * from sb_team_names";
$stmt = $le_db1->query($sql);
$res = $stmt->fetchAll();
$team_arr = array();
foreach ($res as $array){
$team_arr[$array['team_id']] = $array['team_name'];
}
$url = './team_arr.php';
$str = '<?php return ' .'$team_array='.var_export($team_arr,true).';';
file_put_contents($url,$str);
}
- 數(shù)組和獨(dú)享互轉(zhuǎn)函數(shù)
public function arrayToObject($e)
{
if (gettype($e) != 'array') return;
foreach ($e as $k => $v) {
if (gettype($v) == 'array' || getType($v) == 'object')
$e[$k] = (object)$this->arrayToObject($v);
}
return (object)$e;
}
public function objectToArray($e)
{
$e = (array)$e;
foreach ($e as $k => $v) {
if (gettype($v) == 'resource') return;
if (gettype($v) == 'object' || gettype($v) == 'array')
$e[$k] = (array)$this->objectToArray($v);
}
return $e;
}
}
