將Postgres數據庫轉換爲JSON時變爲空

Question

我試圖用PHP轉換Postgres數據庫中的表。事情是，我在運行腳本時得到空值，並且沒有數據被提取。

這裏是我的代碼：

<?php 
$connection = pg_connect("host=xxx port=5432 dbname=xxxxx user=xxxxx password=xxxxxxxxx"); 

$result = pg_query('SELECT * FROM deals'); 


$rows = array(); 
while($r = pg_fetch_assoc($result)) { 
$rows[] = $r; 
} 
print json_encode(array_values(pg_fetch_all($result))); 
?> 

這是實際的鏈接代碼：

Answer 1

您是否嘗試過消除像

$result = pg_query('SELECT * FROM deals WHERE *filed* != 'null'); 

或

null值

$result = pg_query('SELECT * FROM deals WHERE *filed* != '');
