PHP - Dealing With Notices?

How to turn off notices in PHP 5.3.

Is it possible to turn it off in php.ini?

Hello,

I have just upgraded my wampserver and with it MySQL, PHP and PhpMyAdmin versions. And my scripts, which ran normally before, not burst hundreds of undefined variable and undefined index notices. I realize it's "notices", not "errors" but this is quite irritating. I believe it might be due to some upgrade in PHP scripting rules or something but I don't know what. I hope you can help me.

The first type of notice is "undefined variable". This function will return the notice if I remove the bold red line, where I define the variable as empty before I use it in the loop. I didn't need to do this before.
function statistics($array) {

[color=red][b]$list = '';[/b][/color]

if(is_array($array)) {
foreach($array as $name => $value) {
// Rip out the name of the client.
$list .= "<li>".$name." - ";
// set an integer so we know how many tier2 values we have read.
$x = 0;
foreach($value as $difference => $sum_total) {
// if this is the more than the first tier2 values, use a '+' between the units.
$list .= (++$x > 1) ? " + ".$sum_total." ".$difference : $sum_total." ".$difference;
}
// close the line out.
$list .= "</li>";
}
}
return $list;
}

To avoid the 10+ like notices on the page I declare them empty before the variable's first occurrence. But this sounds stupid to me. Wasn't this one of PHP's benefits, not to have to declare the variable before using it?

I also get about 30+ undefined index notices, e.g.
Quote

Notice: Undefined index: COMPANY XXX in F:\wamp\www\Project Management\main.php on line 37

Notice: Undefined index: USD in F:\wamp\www\Project Management\main.php on line 37

Notice: Undefined index: USD in F:\wamp\www\Project Management\main.php on line 41


Here are those lines:
$income_total = calculate("income");
foreach($income_total as $row) {
$clientID = $row['clientID'];
$clientname = $row['clientname'];
//$client = "<a href=\"index.php?page=Client&amp;do=view&amp;clientID=$clientID\">".$clientname."</a>";
$client = "<a href=\"index.php?page=Project&amp;do=view&amp;sortby=$clientID\">".$clientname."</a>";
$currency = $row['currency'];
$client_sum = $row['client_sum'];
$year_sum = '';
$year_sum  += $client_sum;
$income = '';
$income[$client][$currency] += $client_sum;

$income_list = statistics($income);
$income_all = '';
$income_all[$currency] += $client_sum;
}


Line 37 is: Quote

$income[$client][$currency] =

It's the values assigned to $client and to $currency that seem to cause the notice.

How do I deal with this? I don't just want to turn error/notice display off, I want to resolve this issue.

<?php
if ($beyondportal % 26 == 0 || $beyondportal == 0){ ?>
MY CONTENT
<?php } ; ?>


This code compares my variable $beyondportal and if it is a multiple of 26 counting up from 0, it prints my content.

This is great but sometimes the number comes up a negative that is a multiple counting down from 0 like  -26, -52, etc..

if I could do the opposite of a modulus I would think it would work but I'm not sure how to in php. any suggestions?

Hi

I found a tutorial on dealing with databases he http://www.phpfreaks.com/tutorial/php-basic-database-handling

It's great, except that I need it to do more than just a name; I need first, last, dob and email. I have it figured out how to order, insert and delete, but can someone help me figure out how to do the updating?

The tutorial creates an array called cname and loops through it to do the update, but when I add more fields, it only holds the last fileds (emails in this case)

I just need to be able to update all the fields for each user instead of just the name. Sounds easy but I've gotten nowhere

Everything I have tried is posted below.

Any help? Thanks

Code: [Select]
// INSERT: if we have a name to add...
if($_POST['fname']) {   
// little bit of cleaning...   
$fname = mysql_real_escape_string($_POST['fname']);
$lname = mysql_real_escape_string($_POST['lname']);
$dob = mysql_real_escape_string($_POST['dob']);
$email = mysql_real_escape_string($_POST['email']);
// check for previous entry
$sql_check = "SELECT id FROM test WHERE fname='$fname' AND lname='$lname'";
$res_check = mysql_query($sql_check, $conn) or trigger_error("SQL", E_USER_ERROR);
if (mysql_num_rows($res_check) == 1) {
while ($row = mysql_fetch_assoc($res_check)) {
$id = $row['id'];
}
// update
$sql = "UPDATE test SET Current=1 WHERE id='$id'";
$res = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);
} else {
// insert new name into table   
$sql = "INSERT INTO test (id, fname, lname, dob, email) VALUES ('', '$fname', '$lname', '$dob', '$email')";   
$result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);
}
} // end if
// UPDATE: if we have name(s) to change...

for ($i = 0; $i < count($_POST['udata']['fname']); $i++) {

}

I am using file_get_contents to get file off the internet for  further processing but somtetimes there is error fetching that file off the web in which case it would be nice to try to reload it again but I am not sure what would be best way to do it? How can I jump back on error? I guess there would have to be some jump to label condition, but how do I implement this?
