If I have the following values:
$var1 = AR3,373.31
$var2 = 12.322,11T
How can I create a new variable and set it to a copy of the data that has any non-numeric characters removed, with the exception of commas and periods? The values above would return the following results:
$var1_copy = 3,373.31
$var2_copy = 12.322,11

You could use preg_replace to swap out all non-numeric characters and the comma and period/full stop as follows:
$testString = '12.322,11T';
echo preg_replace('/[^0-9,.]+/', '', $testString);
The pattern can also be expressed as /[^\d,.]+/
