Question

I want something like the following:

$arrayOfValues = array(1,2,3,4);
$sqlArray = mysql_convertToSqlArray($arrayOfValues);

which then will return what in SQL would be:

(1,2,3,4)

but in php would be the string “(1,2,3,4)”

Answer 1

There’s no builtin function specifically for creating SQL arrays, but you could just join the array and wrap it in parentheses:

$arrayOfValues = array(1,2,3,4);
$sqlArray = '(' . join(',', $arrayOfValues) . ')';
