如何从数字中删除点？

Question

I have a form formatted with javascript, which makes numbers look like:

10.000 or 2.300

<form>
<input type="text" name="price_1" value="2.300">
</form>

But i want to store them in mysql without dots. How to remove them?

mysql_query("INSERT INTO prices price_a='price_1' WHERE id ='price_id'");

I see money_format and number_format, but its just format the numbers dont remove anything.

Try this :

str_replace(".", "", $string);
