Number Increase

Jul 22, 2007

I have a code which starts with a letter and then digits follow, an example code looks like

D002482

How can I get php to increase the codes number by 1, leaving the letter the same.

The above would look like

D002483

I tried

$codenum = substr('D002482', 1);
$codelet = substr('D002482', 0,1);
$code2 = $codenum+1;
print $codelet.$code2;

But that seems to remove the 00 at the start of the code.

Increase Number Of Iterations From Within The Loop?

Jul 19, 2010

I'm working on custom pagination system and encountered following problem. When one of the elements is filtered out of the set, the size of the final array is smaller than needed. Therefore I'm looking for a solution to increase the number of iterations from within the loop to always get array consisting of 50 elements.

$limit = 50; //Number of elements I want to fetch
for($x=0; $x<$limit; $x++){
if ($elementIsNotFiltered) {
//add element to $someArray;
}
else {
//increase the number of iterations, so even if some elements are filtered out,
//the size of $someArray will always be 50
}
}

Automatically Increase Number In Table?

Jun 28, 2011

I have a ranking system for a game that me and my friend are designing. What I've done here is get the data from the table and order it by score with the highest score at the top. This way I can automatically create a ranking based on the score. In the code there is a line that says: echo ''; there is where I need the number to be. Starting at 1 and going until there are no more rows to get.

Here's the code:
Code: [Select]<?php
$query="select*fromgamedataORDERBYgamedata.scoreDESC";
$result=mysql_query($query);
$rank=mysql_num_rows($result);

Codeigniter: Make Field Increase By 1 Up To A Number?

Jan 3, 2010

In my validation class I have this:

$fields['a_1'] = 'First Question';
$fields['a_2'] = 'Second Question';
$fields['a_3'] = 'Third Question';
$fields['a_4'] = 'Fourth Question';

This is getting old--I have about 40 of these to write, and each set has matching validation rules:

$rules['a_1'] = 'hour';
$rules['a_2'] = 'hour';
...

Is there a way to say:

$fields['a_' . 1 - 17] = "One, Two"

Etc...

Just curious... if not, I'll brute force it.

Increase A Number In MySQL Through Action Form?

Apr 9, 2009

I was making a voting script so that you click the vote button (when logged in) you would gain points. Here's my current code:

$account = $_SESSION['account'];
mysql_connect($dbhost,$dbuser,$dbpass);
@mysql_select_db("$dbname");
$sqlquery = "UPDATE `accounts` SET `votepoints`='+2' WHERE (`username`='$account'";
$result = mysql_query($sqlquery);
$number = mysql_numrows($result);

Ofcourse the +2 is wrong so I was wondering how im suppose to do that.

Str_replace - /text Displays Correct Number Of Characters, But When A Replacement Is Made, A Check With Strlen() Gives An Increase Of 1?

Something odd going on with str_replace. When I replace a set of double characters with another set (double characters), I get a text length increase of 1.

$gw = array("ll","ch");

//text displays correct number of characters, but when a replacement is made, a check with strlen() gives an increase of 1.This is driving me bonkers!

Increase Date

Nov 22, 2005

So if I have: Code:

$month = date(m);

I want to increase this by one to get the next month, I can add one which is fine. But if we are in December, is there an easy way to have this "rotate" to January (1) instead of going to 13? Not sure if there is a way to do this with the date function. So before somebody posts it, I want to avoid the following if possible: Code:

$curr_month = date(m);
if ($curr_month == "12") {
$next_month = "1";
} else {
$next_month = $curr_month + 1;
}

Memory - Increase Memory_limit?

Sep 15, 2009

In a system I am currently working on, there is one process that loads large amount of data into an array for sorting/aggregating/whatever. I know this process needs optimising for memory usage, but in the short term it just needs to work.Given the amount of data loaded into the array, we keep hitting the memory limit. It has been increased several times, and I am wondering is there a point where increasing it becomes generally a bad idea? or is it only a matter of how much RAM the machine has?The machine has 2GB of RAM and the memory_limit is currently set at 1.5GB. We can easily add more RAM to the machine (and will anyway).
