過濾掉鑰匙,我有以下陣列:從多維數組
array(2) {
[0] => array(4) {
["presentation_id"] => int(143)
["user_id"] => int(2)
["session_id"] => int(46)
["submission_id"] => int(190)
}
[1] => array(4) {
["presentation_id"] => int(144)
["user_id"] => int(2)
["session_id"] => int(46)
["submission_id"] => int(190)
}
我想是有由該陣列的只是某些鍵的陣列,例如:
array(2) {
[0] => array(4) {
["presentation_id"] => int(143)
["user_id"] => int(2)
}
[1] => array(4) {
["presentation_id"] => int(144)
["user_id"] => int(2)
}
任何想法?
你有沒有考慮過使用循環? – Rijk
