字符串中十进制数的正则表达式

Question

SetColoursSizes('0', '[Select Colour]', '0', '[Select Size]', 0,585.00,500.00);

This is an example of the string I'd like to match in PHP, and then caputre the last two variables, in case, '585.00' and '500.00'. Note: these numbers should be flexible in that they could be anything from 0.50 to $1500.00.

Can anyone help with the PHP/RegEx for this?

Cheers, Michael

Answer 1

This regex will work:

SetColoursSizes\s*\([^(]+,\s*([0-9.$]+)\s*,\s*([0-9.$]+)\s*\)

Answer 2

$matches = array();
preg_match('~([\d\.]+),\s*([\d\.]+)\);$~', $yourString, $matches);

$matches[1] and $matches[2] should have the two numbers.

Answer 3

The following code captures your final two number/decimal arguments in $matches[2] and $matches[3]:

<?php
  $matches = array();
  preg_match('/SetColoursSizes\(([^,]+,\s*){5}(\d+\.?\d*),\s*(\d+\.?\d*)/', "SetColoursSizes('0', '[Select Colour]', '0', '[Select Size]', 0,0.50,500.00);", $matches);
  print_r($matches);
?>
