我試圖用我的數(shù)據(jù)庫的數(shù)據(jù)生成一個 json，所以當我收到數(shù)據(jù)時一切都很好，當我將數(shù)據(jù)以 JSON 格式放置時就會出現(xiàn)問題，看起來這是錯誤的：{"comment":[{"id_comment":1,"photo":"imgU\/default.png","full_name":"MercadoPago","comment":"Primero"}]}{"comment":[{"id_comment":2,"photo":"imgU\/default.png","full_name":"MercadoPago","comment":"Segundo"}]}所以我想生成一個看起來像這樣的json：[{"id_comment":1,"photo":"imgU\/default.png","full_name":"MercadoPago","comment":"Primero"},{"id_comment":2,"photo":"imgU\/default.png","full_name":"MercadoPago","comment":"Segundo"}]我的代碼是下一個：global $id_comentador;global $id_comentario;global $comment;$arregloComentarios = json_decode($row['comentarios'], true);foreach ($arregloComentarios as $value) { $id_comentario = $value["id_comentario"]; $id_comentador = $value["id"]; $comment = $value["comment"]; $consultarComentador = "select id,first_name,last_name,foto from users where id='$id_comentador';"; $coo["comment"] = array(); $arregloProyectos = traerDatos($consultarComentador); $num = count($arregloProyectos); if ($num > 0) { foreach ($arregloProyectos as $row2) { $foto = $row2["foto"]; $foto2 = $row2["first_name"]; $foto3 = $row2["last_name"]; $tmp = array(); $tmp["id_comment"] = $id_comentario; $tmp["photo"] = $foto; $tmp["full_name"] = $foto2.''.$foto3; $tmp["comment"] = $comment; global $coo; $coo['comments'] = array(); array_push($coo["comments"], $tmp); }//Cierra foreach echo json_encode($coo); }}我將不勝感激您的回答。

$comments在頂部之外創(chuàng)建一個數(shù)組foreach并推入該數(shù)組而不是$coo["comments"]. 然后，echo json_encode($comments)在外面做之后foreach。
global $id_comentador;
global $id_comentario;
global $comment;
$arregloComentarios = json_decode($row['comentarios'], true);
$comments = [];
foreach ($arregloComentarios as $value) {
$id_comentario = $value["id_comentario"];
$id_comentador = $value["id"];
$comment = $value["comment"];
$consultarComentador = "select id,first_name,last_name,foto from users where id='$id_comentador';";
$arregloProyectos = traerDatos($consultarComentador);
$num = count($arregloProyectos);
if ($num > 0) {
foreach ($arregloProyectos as $row2) {
$foto = $row2["foto"];
$foto2 = $row2["first_name"];
$foto3 = $row2["last_name"];
$tmp = array();
$tmp["id_comment"] = $id_comentario;
$tmp["photo"] = $foto;
$tmp["full_name"] = $foto2.''.$foto3;
$tmp["comment"] = $comment;
$comments[] = $tmp;
}//Cierra foreach
}
}
echo json_encode($comments);
