子句mysql中逗号分隔的字符串IN数组

I have a array like that :

 $myarray=  'zzz,aaa,bbb'  ;

and want use it in mysql IN clause like that :

 "...  WHERE ids IN ($myarray) "   // didnt work 
 "...  WHERE ids IN ('$myarray') " // didnt work

the error im getting is that the first value in that array zzz says that zzz is not a column name . so i understand that i must separate the values with quotes to be like that :

 $myarray=  ' "zzz","aaa","bbb" '  ;

But i have no clue to do that . any help would be much appreciated.

    You need to explode() your string and then implode() it - 

    $myarray = 'zzz,aaa,bbb'; 
$realArray = explode(',', $myarray);
$stringForIn = "'" . implode("','", $realArray) . "'";
echo "WHERE ids IN ($stringForIn)";

    $myarray = 'zzz,aaa,bbb';
$myarray = implode("','",explode(',',$myarray));
$query   = "..... WHERE ids IN ('$myarray')";

    Try that : 

    $myarray=  'zzz,aaa,bbb'  ; 
echo implode '"' . ('","', explode(',', $myarray)) . '"';
