[PHP-DB] data formats
I'm submitting form data which is a mixture of checkboxes and text inputs, some of which are integers and a couple text based. I am retrieving the data as follows: $var = (int)!empty($_POST['var']); for checkboxes, $var = (int)$_POST['var']; for integers and $var = mysql_real_escape_string($_POST['var']); Is this correct? -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DB] Re: Online PHP-Mysql Meeting
Due to time zone differences, people in various zones (countries/continents) can only avail of a live event within a certain time period. A recorded presentation can be viewed by anyone anytime anywhere. No time zone constraints. Obviously, whoever is taking on the role of tutor in a live event has their own time restrictions/schedule, so I think if this is is going to be a live event, see who is available/able to take on the role of tutor in various zones so everyone else knows which live event best suits their own schedule if they want to attend/tune in. Then decide/debate on the best available format for the event and any associated QA.

[PHP-DB] resources and resource types
When I did a search on resource(5) within the PHP online documentation, I found the resource page resource.php. While although it lists all the resources used with mysql, it does not mention how resources are related to resource numbers as above. A query such as a row count on a table results in an integer value. What is the best way of accessing or converting the integer value from the resource? I can't see any particular function in the function list which does this, without getting into strings or arrays, or have I missed something blaringly obvious, hope not? -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

giving me any error msgs such as cannot connect.

Still no luck then. Try selecting the DB without the connection parameter:
$dbConnect=mysql_select_db('questions');
And don't forget to set error_reporting(E_ALL) above your code.

Turn line 13 into

, so leave out the connection parameter and append the die()

and see what error that produces.
OK. Tried that and count comes back as 1.

Even if an array has only one value, it is still an array and foreach will run
it.
?php
$arr[] = I'm an array.;
if(is_array($arr))
{
foreach($arr as $val)
{
echo $val;
}
}
?
The above code outputs:
I'm an array.

So if I use:
$query = Select answer from answers where studentID='A123456789';
$result = mysql_query($query,$connection) or die(mysql_error());
while($row = mysql_fetch_assoc($result))
{
foreach($row as $answer)
{
echo $answer . \n;
}
}
I thought I would be able to print out each array element, but I am not getting
any output. Has anyone got a better idea?
