PHP - Quick Question About Sleep Function

how to open a site with curl that has frames ?

when ive tried it gives "your broswer does not support frames" ...

Does storing multiple values in 1 database field with a varchar let's say set at 150, all separated by
"|'s" so I don't have to create a field name for each one is it better performance wise or no? (storing 6-7 different |'s that will be outputted with a array ofc)

?

The Question

many thanks

code

<?php
//storecodefound.php v1.0
//purpose is to store the http refer and the code associated with the site to a db to be collected and verified by submitcode.php
$code = $_GET['code'];
$site = $_SERVER['HTTP_HOST'];


//check to see if the code already present
$connect = mysql_connect("localhost","root","") or die (mysql_error());
$check = mysql_query("SELECT code FROM hunter.codes WHERE code='$code'") or die (mysql_error());
$row = mysql_num_rows($check);
echo "result of \$row is ".$row;
echo "<br />";
if ($row = 0) {
//insert into db cause it's not there
mysql_query("INSERT INTO hunter.codes (id, code, site)
VALUES ('','$code','$site')") or die (mysql_error());
}
else {
//echo it's already here
echo "Code already found on server!";
}





?>

my question is the result of $row is infact 0 and the if statement says if $row is 0 to insert into db and instead it's given me the code is already found?

Is there a way to only output the first, say, 30 words of a variable? I have a way to do it in mind, but seems like it's messy and not practical.

Any suggestions?

E.g:

WITHOUT LIMIT: Welcome to my store. Would you like to buy something? We have really good noodles and fishes in doodle pools.
WITH LIMIT: Welcome to my store. Would you like...

Sort of like a short preview.

I am starting to learn PDO by re-writing one of my existing scripts. Do I still need to validate $_GET or does PDO do the work for me?  Currently I am using:

Code: [Select]
$id = $_GET['id'];

$sth = $dbh->prepare('DELETE FROM van_reservations WHERE id = :id');
$sth->bindParam(':id', $id, PDO::PARAM_INT);
$sth->execute();

I used to validate by using this:

Code: [Select]
$id = isset($_GET['id']) && is_numeric($_GET['id'])?(int) $_GET['id']:0;

What is the difference between these two lines


Code: [Select]
!isset($_POST[$requiredField])
and

Code: [Select]
!$_POST[$requiredField]

hi.
when i get into some function manual and there is a note says.
Quote

This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.

.
is that meaning that after 5.3.0 version this function will not be supported?
thanks , Mor.

hey! I have a site where I want to use multiple issets at the same time, like if I have four buttons and four issets:
if(isset($_POST['one']))
{
echo '<div class="example_box">one</div>';
}

if(isset($_POST['two']))
{
echo '<div class="example_box">two</div>';
}

if(isset($_POST['three']))
{
echo '<div class="example_box">three</div>';
}

if(isset($_POST['four']))
{
echo '<div class="example_box">four</div>';
}


but for some reason it seems like only one isset can be activate at a time, is there any way to work this out or something :s?

I've tried some variants of elseif stuff and such, but yeah, I'm pretty new at this stuff

Hi, I've seen code like this multiple times, but I don't really know what it means.

function funcName(&$something) {
    // whatever
}

What exactly does the "&" do before the variable?

How can I make this function say if $id is a set parameter, use it.  If not, use globals $user_info['uid']?

Code: [Select]
function fetch_user_info_by_id()
{
global $user_info;

$sql = "SELECT
`users`.`id`,
`users`.`firstname`,
`users`.`lastname`,
`users`.`username`,
`users`.`email`,
`users`.`gender`,
`users`.`accounttype`,
`users`.`personalweb`,
`users`.`guestviews`,
`users`.`iviews`,
`users`.`eviews`,
`users`.`credentials`,
`users`.`specialties`,
`users`.`country`,
`users`.`city`,
`users`.`state`,
`users`.`phonenumber`,
`users`.`dateofbirth` AS `dob`,
`iQuestions`.`investortype`,
DATE_FORMAT(`users`.`dateofbirth`,'%D \of %M %Y') AS `dateofbirth`,
DATE_FORMAT(`users`.`signupdate`,'%D %M %Y') AS `signupdate`,
SUM(`companies`.`capitalrequested`) AS `totalrequested`,
SUM(`iQuestions`.`capitalavailable`) AS `totalavailable`
FROM `users`
LEFT JOIN `companies`
ON `users`.`id` = `companies`.`adminid`
LEFT JOIN `iQuestions`
ON `users`.`id` = `iQuestions`.`userid`
WHERE `users`.`id` = '${user_info['uid']}'";

$result = mysql_query($sql);

return mysql_fetch_assoc($result);
}

Long story short i'm paginating database results. So pages = results / res-per-page-limit

but 28 / 10 will be 2.8 should i use round() or ceil()?

Say, Code: [Select]
$ok = 'ABCDEFG'
What is the command to check whether $ok contains 'C'?

I need to use a HTML  form to retrieve data in a certain order of ascending/descending using a drop down box and a true/false statement button for one of the values from a MySQL database. Im guessing I need a php script to query the database, but can I add the php code to the HTML or upload a php to the server that links the HTML thank you

Can I replace the set message text for $body and $subject with $_POST['message']; $_POST['subject']; so I can get a users input from a html form via php as the action.  Instead of the set text in the script.
