PHP float / double is stored as MySQL DECIMAL
I am having a really strange problem with storing values ββin MySQL. Package:
I have a table that uses DECIMAL(15,8)
to store monetary values ββ(like the whole order), but when I try to insert like:
2,45545345
this is saved as
2.00000000
I tried MySQL FORMAT / CAST but still the same result.
This is how the request is generated:
$db->query("INSERT INTO `random_table_name` SET currency_value = '" . floatval($value) . "'");
I have also tried doubleval
but same result. The funny thing is, this same piece of code worked great a couple of weeks ago and I can't remember any changes to the db structure or db class that might cause this.

Use number_format to replace ,
with.
Like this:
number_format($value, 8, '.') // 8 = number of decimals, . = decimal separator
However, your problem seems to be related to the current locale. You need to look into the following: setlocale () and localeconv
setlocale(LC_ALL, 'en_US'); // NOT TESTED, read up on the appropriate syntax
This is a suitable way to do it, an alternative would be (as suggested below) to do it str_replace(',', '.')
, but you must do the opposite every time you want to output lines.
There is another option, but you can set the MySQL locale to en_US
.

Replace ,
with .
before inserting into db:
$value = str_replace( ',', '.', $value);
This will create a valid number that can be safely inserted into the database. Or just add it directly to your request:
INSERT INTO `random_table_name` SET currency_value = '" . str_replace( ',', '.', $value ) . "'
