if variable contains a character?

[patrick99e99]

Hi, I am just wondering how the best way to accomplish this is:

$discount = "20%"

$discount = "20$"

if ($var contains "%")
{
$discount=value of $discount
$discount_type="percent"
}
else if ($var contains "$")
{
$discount=value of $discount
$discount_type="dollars"
}

so ideally $discount will be set to "20" (no % or $)
and the discount_type will tell what it was...

thanks in advance.

strpos()

Thanks! That answers part of my question.. Now, how can I set a string to the numeric value of a string? In other words if $a="20%" or $a="$20", how can I make $a="20"

?

Thanks again.

This should do it:

if (strpos($discount, '%') !== false) {
    $discount = str_replace('%', '', $discount);
    $discount_type = 'percent';
} elseif (strpos($discount, '$') !== false) {
    $discount = str_replace('$', '', $discount);
    $discount_type = 'dollars';
} else {
    // Invalid data
}
