来自MySQL Assoc的PHP数组

Question

Confusing my values so messy

Home Code

$user = getventList();
    $response = array();
    if(mysql_num_rows($user) > 0){
    while ($row = mysql_fetch_assoc($user)){
         $response[] = $row;
         echo json_encode($response);
    }
    } else {
         return false;
    }


enter code here

Function event this one is function to generate result from mysql

$result = mysql_query("SELECT * from event where status = '2'"); return $result;

Bad Result

[  {"cPID":"123","image_event":"enjoy.jpg"} 
]

[  {"cPID":"123","image_event":"enjoy.jpg"},
   {"cPID":"1234","image_event":"enjoy.jpg"}
]

[  {"cPID":"123","image_event":"enjoy.jpg"},
   {"cPID":"1234","image_event":"enjoy.jpg"},
   {"cPID":"12345","image_event":"enjoy.jpg"}
]

[  {"cPID":"123","image_event":"enjoy.jpg"},
   {"cPID":"1234","image_event":"enjoy.jpg"},
   {"cPID":"12345","image_event":"enjoy.jpg"},
   {"cPID":"123456","image_event":"enjoy.jpg"}
]

[  {"cPID":"123","image_event":"enjoy.jpg"},
   {"cPID":"1234","image_event":"enjoy.jpg"},
   {"cPID":"12345","image_event":"enjoy.jpg"},
   {"cPID":"123456","image_event":"enjoy.jpg"},
   {"cPID":"1234567","image_event":"enjoy.jpg"}
]

i wanna get only like the last array

[  {"cPID":"123","image_event":"enjoy.jpg"},
   {"cPID":"1234","image_event":"enjoy.jpg"},
   {"cPID":"12345","image_event":"enjoy.jpg"},
   {"cPID":"123456","image_event":"enjoy.jpg"},
   {"cPID":"1234567","image_event":"enjoy.jpg"}
]

Answer 1

Move json_encode out of the while loop. Additionally quit using mysql and start using mysqli or PDO functions.

$user = getventList();
    $response = array();
    if(mysql_num_rows($user) > 0){
    while ($row = mysql_fetch_assoc($user)){
         $response[] = $row;          
    }
    } else {
         return false;
    }
    echo json_encode($response);

Now your output will be the expected one

[  {"cPID":"123","image_event":"enjoy.jpg"},
   {"cPID":"1234","image_event":"enjoy.jpg"},
   {"cPID":"12345","image_event":"enjoy.jpg"},
   {"cPID":"123456","image_event":"enjoy.jpg"},
   {"cPID":"1234567","image_event":"enjoy.jpg"}
]
