I have a textarea and I want to insert values of that textarea to a mysql table. But I want to insert each line to each field. Like the textarea has 3 lines...each line should be inserted in 3 each field in the table. Can anyone please help me with this.
Regards,
Explode the value of the textarea (see PHP manual for the syntax of explode). You will end up with a string array with 3 items. Now you can process each of these items individually.
Do you really mean columns (fields) and not rows? If someone enters 100 lines in the textarea you would neet 100 columns. This is considered to be bad data design.

I want to duplicate the last record in my table every minute, i'm using php and mysql.
I can use a cronjob to run it every minute, i know how to do that.
But i don't know how to duplicate the last row, i only have an id that auto_increment and value column.
For example :
Id, Value
10, Green
11, Green
12, Green
13, Green
I think select into is what you are looking for.

When user from specific area see properties list on website and if he selects acre in dropdown list then he can see the every property area in the acre though the property was listed in another unit.

table 2: [1,1,2,100],[1,3,1,0.000001]
First entry in the table to for converting CM to M and second row is to convert from KM to CM.
Hope it helps..

I'm trying to obtain a column name EmailId from the table named Users. But it returns only the first string and nothing else?
PHP:
$sql="SELECT EmailId FROM Users;";
$result =mysqli_query($conn,$sql);
$col=mysqli_fetch_array($result);
The database has 3 email-ids but count($col) returns only 1. Why so?
Thanks in advance.
The database has 3 email-ids but count($col) returns only 1. Why so?
Because
$col=mysqli_fetch_array($result);
only fetch the first row according to the internal pointer of the dataset, and therefore
count($col)
returns 1 because $col is an array having 1 item.
