Question

i have use function for inserting data to my sql.
the data is

function mysql_insert($table, $arr){
if($arr!=''){
    $values = array_map('mysql_real_escape_string', array_values($arr));
    $keys = array_keys($arr);
    $q=('INSERT INTO `'.$table.'` (`'.implode('`,`', $keys).'`) VALUES (\''.implode('\',\'', $values).'\')');
    //$res = mysql_query($q)OR die(mysql_error());
    return $q;
}else{
    return false;
}

data and query is came from :

if($crud=='insert'){
$field= array(  'col1' => 'apel',
        'c0l2' => 'box1',
        'col3' => 200,//integer Quantity
    );
$data=mysql_insert('wh',$field);}echo json_encode($data);

and result is
= “INSERT INTO wh (col1,c0l2,col3) VALUES (‘apel’,’box1′,’200′)”
that col3 have value as string. i need that col3 as integer.
what wrong with this code?

Answer 1

This is happening because the command implode('\',\'', $values) is telling it to turn the array $values into a string, with single quotes and commas between each element. If you want to not put quotes around numbers, you’ll need to iterate over $values with a more specific function.

However, it doesn’t actually matter. If you give MySQL a string containing a number for a numeric field, it will just convert it to a number of the appropriate type. You can leave it as-is and everything should work.
