PHP newbie here. I've created a function that increases prices based on their price range:

function update_price ( $price) 
 If (isset($price) ) 
 if ($price < 60 ) 
 return $price + 40;
 
 elseif ($price >= 60 && $price < 100) 
 return $price + 60;
 
 elseif ($price >= 100 && $price < 200) 
 return $price + 70;
 
 elseif ($price >= 200 && $price < 300) 
 return $price + 80;
 
 elseif ($price >= 300 && $price < 450) 
 return $price + 90;
 
 elseif ($price >= 450) 
 return $price + ($price * .2);
 
 

The function is called when I import a CSV file. Works great, except for the last part of the function. I'm trying to raise the price of those qualifying products by 20%, so I'm taking $price and adding ($price * .2). But a product that was $628.74 is coming out as $754,888.00 instead of $754.88.

What did I do wrong?

It's OK that PHP returns 754.488, it's the same value returned by a calculator:
628.74÷5+628.74=754.488

Here you would need to round the precision to 2 decimal numbers, this can be done with the round() function.

Also, I would write your function like this:

 function update_price($price) (!is_numeric($price)) 

im not sure what your doing to give you that error but

Testcode

$base = 628.74;
$change = round($base * 0.2,2);
$new = $base + $change;
$allatonce = round(($base+($base*0.2)),2);
print_r(array($base,$change,$new,$allatonce));

Output

Array ( [0] => 628.74 [1] => 125.75 [2] => 754.49 [3] => 754.49 )

the all at once value would fit your needs.
