MySql搜索查詢無法返回包含％20的行

Question

我的數據庫查詢出現問題。當我嘗試拉空間轉換爲％20的行時，查詢返回null。我測試了其他行工作正常，爲什麼會發生此問題？我是否需要從每行中手動刪除％20以使其正常工作？

謝謝！

<?php 

include_once 'includes/db_connect.php'; 

$query = "SELECT * FROM USERS WHERE LIKES= '$_GET[imgname]' "; 

//Creating resonse json array, with another array inside 
$jsonResponse = array("info" =>array()); 

if($result = mysqli_query($mysqli, $query)) { 
    while($row = mysqli_fetch_assoc($result)){ 

    $jsonRow = array(  

     'names'   =>  $row['USERNAME'], 
     'userIds'   =>  $row['USERID'] 

     );   

     //adding the $jsonRow array to the end of the "users" array as key/value 
     array_push($jsonResponse["info"], $jsonRow); 
    } 

} 
    //encoding to json for the app 
    echo json_encode($jsonResponse); 



?>

更改您的SQL查詢：

$query = "SELECT * FROM USERS WHERE LIKES= '".rawurlencode($_GET[imgname])."' "; 

的LIKES列有編碼的圖像路徑（空間轉換到%20）。因此，$_GET[imgname]應該被編碼以匹配數據庫記錄。
