Question

I know this question is simple, but I have little experience with arrays and am having difficulty. Anyway I have this array:

$variables=array("$value1" => "int",$value2 => "var",$value3 => "int");

I want to cycle through it and for each $value I would like to add

$stmt->bindValue(1,$value, PDO::PARAM_INT); if $value is ‘int’ or

$stmt->bindValue(1,$value); if $value is ‘var’

and have the ‘1’ increase as it cycles through the variables. Does anyone know how to do this?

Answer 1

A foreach loop lets you loop through your array. The foreach ($array as $k=>$v) syntax lets you define a variable to hold the current key ($k) and one for the current value ($v). I also used a simple variable that is incremented in every cycle ($i).

Then a simple if–elseif combo is used to do something different.

$i=1;
foreach ($variables as $k=>$v) {
    if ($v=='int') {
        $stmt->bindValue($i, $k, PDO::PARAM_INT);
    }
    elseif ($v=='var') {
        $stmt->bindValue($i, $k);
    }
    $i++;
}

This can be optimized further, I wanted to show the logic.
