創建一個變量，同時循環導致

Question

while ($topic = mysql_fetch_assoc ($result)); { 
    echo "{$topic["overtag "]} "; 
} 

從我while循環的結果顯示爲這樣： 蘋果橘子香蕉

我希望能夠把所有這些成果，並把它們放在一個變量，並它看起來像這樣： $ fruits = apple orange banana

我該如何做到這一點？

Answer 1

concatination運營商。=

$fruits = ''; 
while ($topic = mysql_fetch_assoc ($result)); { 
    $fruits .= "{$topic["overtag "]} "; 
} 

Answer 2

你只需要每一個串聯到變量循環

$fruits = ""; 
while ($topic = mysql_fetch_assoc ($result)); { 
    echo "{$topic["overtag "]} "; 
    $fruits .= $topic['overtag'] . " "; 
} 
// This is going to result in an extra space at the end, so: 
$fruits = trim($fruits); 

哦裏面，另外，你有哪些是要打破一個錯誤分號你while循環：

while ($topic = mysql_fetch_assoc ($result)); { 
            --------^^^-- 

應該是：

while ($topic = mysql_fetch_assoc ($result)) { 

Answer 3

// I love arrays. 
$fruits = array(); 
while ($topic = mysql_fetch_assoc ($result)); { 
    $fruits[] = (string)$topic["overtag "]; 
} 

// If you don't want an array, but a string instead, use implode: 

$fruits = implode(' ', $fruits)

使用下面的PHP代碼，你可以在網頁從數據庫表並顯示數據：

$sql_query="select * from yourTable"; 
    $result=mysqli_query($connection,$sql_query); 
    if(mysqli_num_rows($result) > 0) 
    { 
     while($row = $result->fetch_array(MYSQLI_ASSOC)) 
     { 
     echo "ID ".$row[0];//echo "ID ".$row["ID"]; 
     echo "Name ".$row[1];//echo "Name ".$row["Name"]; 
     } 
    } 
    else 
    { 
     echo "No Record"; 
    }
