使用PHP & codeigniter。 我下面张贴到我的PHP API 从前端提交 - >{"academicYear":"2015","subjectClassification":"Primary","subjectId":"55","teacherId":[10,16,17]}
PHP如何从字符串后找到数组值
我需要在我的PHP代码找到或打印teacherId值。 基本上我的目标是打印“HELLO”3次,如果在teacherId
阵列中有3个Id。
我的代码看起来像下面,
function subjectTeacherAllocation_post(){
$data = remove_unknown_fields($this->post() ,$this->form_validation->get_field_names('subjectTeacherAllocation_post'));
$this->form_validation->set_data($data);
var_dump($data);
$teacherList = array($data['teacherId']);
echo $teacherList[0];
echo array_values($teacherList);
的var_dump输出 - >array(3) { ["academicYear"]=> string(4) "2014" ["subjectId"]=> string(2) "55" ["teacherId"]=> array(3) { [0]=> int(9) [1]=> int(15) [2]=> int(32) } }
你得到的输出是什么echo'teacherList [0];'''''echo array_values($ teacherList);''' – Rifky
