How do you run a MySQL query from PHP file?

Here is a simple script that you can do to run a MySQL query after you have set a database up. <?php // Database Settings $db['hostname'] = "localhost"; $db['username'] = "<db username>"; $db['password'] = "<db password>"; $db['database'] = "<db name>"; // Connect to MySQL $connect = mysql_connect($db['hostname'], $db['username'], $db['password']); // Select Database mysql_select_db($db['database'], $connect); // Do MySQL Query mysql_query("INSERT INTO table_name SET field_name = '1234567890'"); // Close MySQL mysql_close($connect); ?> Obviously you will need to use your own MySQL settings and database details, but this gives you a general overview of how you can do it.


How do you convert db to mw?

To convert from dB (decibels) to mW (milliwatts), you can use the formula: mW = 10^(dB/10). Simply take the dB value and divide it by 10, then raise 10 to that power to get the mW value. For example, if you have 20 dB, the calculation would be mW = 10^(20/10) = 100 mW.


How do you convert 40w to db?

To convert power in watts to decibels (dB), you can use the formula: dB = 10 * log10(P2/P1), where P1 is the reference power (usually 1 watt) and P2 is the power you are converting (40 watts in this case). Plugging in the values, you would calculate: dB = 10 * log10(40/1) = 16.02 dB.

How many milliwatts in 36 dB?

To convert decibels to milliwatts, you can use the formula: milliwatts = 10^(dB/10). In this case, for 36 dB, the calculation would be: 10^(36/10) = 10^3.6 = 3981.07 milliwatts. Therefore, there are approximately 3981.07 milliwatts in 36 dB.

What do you measure noise in?

If you would like to measure how loud the sound is, dB, decibels, would be good. To give you a rough idea, a whisper is about 30 dB, a baby crying loudly about 100 dB. Also, if you like to measure the frequency or the wavelength, you can use Hertz.


How loud is 100 db?

100 dB is considered very loud and can cause hearing damage with extended exposure. It is approximately as loud as a chainsaw, a jackhammer, or a rock concert. It is recommended to use ear protection in environments with noise levels reaching 100 dB.


How do you converts ohms to dB?

You must find a resistance value for 0 dB as reference. If 1 Ohm = 0 dB then 10 ohms = 20 dB and 100 ohms = 40 dB.
