php mysql查詢字符串數組

Question

我正在建立一個字符串，我檢查mysql數據庫。

eg: 
formFields[] is an array - input1 is: string1 
array_push(strings, formFields) 
1st string and mysql query looks like this: 
"select * from my table where id in (strings)" 

formFields[] is an array - input2 is: string1, string2 
array_push(strings, formFields) 
2nd string and mysql query looks like this: 
"select * from my table where id in (strings)" 

formFields[] is an array - input3 is: string1, string2,string3 
array_push(strings, formFields) 
3rd string and mysql query looks like this: 
"select * from my table where id in (strings)" 

我會想添加單引號和逗號陣列，這樣我有這樣的字符串數組： 「從我的表中選擇*，其中ID在（‘STRING1’，‘字符串2’，」 string3'）「

我試過使用數組implode，但仍然沒有運氣有任何想法？感謝

Answer 1

'SELECT ... WHERE id IN ("' . implode('","', $strings) . '")'; 

Answer 2

implode("','",$array); 

Answer 3

implode()是解決辦法，但你不應該忘記轉義數據：

$data = array(...); 
array_walk($data, function(&$elem, $key) { 
    $elem = mysql_real_escape_string($elem); 
}); 
$sql = 'SELECT ... id IN ("' . implode('", "', $data) . '");';
