在PHP中將多維數組放大為單個逗號分隔的列表

Question

如果我有一個像這樣的數組：

Array ( [0] => abcdef )
Array ( [0] => abcdef [1] => abcdef )
Array ( [0] => abcdef [1] => abcdef [2] => abcdef )
Array ( [0] => abcdef [1] => qwerty ) 

並想要創建一個逗號分隔的列表，例如：

abcdef, abcdef, abcdef, abcdef, abcdef, abcdef, abcdef, qwerty

我該怎么做？

當我嘗試像這樣分解數組時：

while($row = mysql_fetch_array($search)){ 
    $row2 = $row['scholarshipid']; 
    $newarray = unserialize($row2);
    $unique_array = array_unique($newarray, SORT_REGULAR);
    $commaList = implode(', ', $unique_array);
    echo "$commaList";
    //print_r($newarray); 
} 

$commaList = implode(', ', $unique_array);

我得到：

abcdefabcdefabcdefabcdef, qwerty

Answer 1

從評論中可以看出，您顯示給我們的輸出來自循環。 因此，您首先必須將每次迭代中的所有數組收集到1個變量中，然后可以將其內爆，例如

$result = [];

while($row = mysql_fetch_array($search)){
    $row2 = $row['scholarshipid'];
    $newarray = unserialize($row2);
    $unique_array = array_unique($newarray, SORT_REGULAR);
    $result = array_merge($result, $unique_array);
}

echo implode(",", $result);

Answer 2

你可以像這樣更新

$temp = array();
while($row = mysql_fetch_array($search)){ 
    $row2 = $row['scholarshipid']; 
    $newarray = unserialize($row2);
    $temp = array_merge($temp, $newarray);

}
$commaList = implode(', ', $temp);
print_r($commaList);

一切都完成了：P
