PHP, Regular expression to extract string to float number

Question

I have a string = '0.25MM X 1219MM X COIL'. Also sometimes those string is = '0.25MM X 1219MM'

I try With regular expression :

 preg_match_all('!\d+!', trim($modelCoil['size']), $matches);
 VarDumper::dump($matches);

I get :

[
   0 => [
      0 => '0'
      1 => '25'
      2 => '1219'
   ]
]

The result that expected :

[
    0 => '0.25.00'
    1 => '1219.00'
]

Please advise.

Answer 1

Your regex is just searching for \d+. You are wanting to include decimal points (.) in your results.

You might want to try searching for \d[\d\.]* or similar to include the dot.
