Hi Experts

Could you point how to deal with this kind of PHP notation?

f.e.
%company_id$d

$query = static::procedure_query('call', 'get_dashboard_current',
            '%company_id$d, %date_begin$s, %date_end$s, %month$d, %group_id$s', $params);

Open in new window


The legacy code I'm maintaing is FuelPHP, I don't know if it's a particular feature of FuelPHP or of in general PHP.

Thanks in advance

I suspect that usage is peculiar to your code or FuelPHP.  The standard usage for '%' is as a modulus operator in arithmetic.  http://php.net/manual/en/language.operators.arithmetic.php

Hi

I really could not find the meaning of this code.
By the way the app is perfectly running...

Judging on my light research, I'm guessing this was a wrapper around a method used to call parameterized procedures through the FuelPHP DAL.  It does not appear to be any standard syntax from Fuel.  The syntax of the parameters looks like a custom format: '%', <name of parameter>, '$', <type of data>.  For example, the first would be a decimal/integer parameter named company_id.  I would also guess that $params is an array in which the keys match those parameter names.

This is all guesswork, though.  You'll need to find the definition of procedure_query() to know for sure.

Looks furiously like the arguments for a "prepared SQL statement" that the php code would pass to a SQL query.
