I have the following number: "4.000.00" I need to delete the point and the two 0 the right in (php 5) thank you!
I tried with:
preg_replace('/^(\d+)\.0+$/', '$1', $this->input->post('valor'));
trim($this->input->post('valor'),0); //solo quita el 00 pero no el "."
Following the example you added, you can delete the decimal point in the same way with trim :
The code would be like this:
trim(trim($this->input->post('valor'),0), '.');
Use the number_format function:
$var = 4000.00;
echo number_format($var,0);
Take into account that you should not have a , otherwise you would have problems with the variable, because PHP would try to take it as a string.
