These are my strings
2012-13
2013-14
2014-15
2015-16
2016-17
2017-18
I my string is 2014-15 as current financial year, I want my next my next financial year as 2015-16
How can I achieve this with PHP? I get these year list form mysql table, but I want next financial year in php
Try this:
$financial_year = "2012-13";
$fin_array = explode("-", $financial_year);
$next_fin_array[0] = $fin_array[0] + 1;
$next_fin_array[1] = $fin_array[1] + 1;
$next_financial_year = implode("-", $next_fin_array); // Gives 2013-14
Hope this helps.
$myStr = '2014-15';
$yr1 = (int) substr($myStr, 0, 4);
$yr2 = (int) substr($myStr, -2);
echo ($yr1+1).'-'.($yr2+1);
// 2015-16
$financeYear = DateTime::createFromFormat ( "Y-d" ,"2014-15");
$financeYear->modify('+ 1 year');
echo $financeYear->format("Y-d");
Result
2015-15

Hi am having 10 elements in array . Am trying to get my random element mostly from first 5 elements. Which means random element appearance from first 5 elements should be much greater than next 5 elements
$arr = array('a','b','c','d','e','f','g','h','i','j');
$random = $arr[array_rand($arr)];
Am using above one to get the random element normally
Use function rand(min_num, max_num):
function rand5($array) {
$part = rand(1, 10);
return ($part > 3) ? $array[rand(0, 4)] : $array[rand(5, 9)];
}
$arr = array('a','b','c','d','e','f','g','h','i','j');
$random = rand5($arr);
Try this simple and easy code :-
$arr = array('a','b','c','d','e','f','g','h','i','j');
$rand = rand(0,9);
echo $arr[($rand <= 6 ? ($rand%5) : $rand)];
You just have to get the random number between 0 to 9 and divide that number in 70%(0-6) and 30%(7-9). If its greater than 5 then only use the remainder else directly get that number

I just want to know how to convert inch based on the integer inputted in the field.
For Example:
$int = $_POST['int']; //value 1
//computation here...
$inch = //formula
//echoing the inch
echo $inch;
If you want convert from centimeter can you use this source
function cm2inches($cm)
{
$inches = $cm/2.54;
$inches = $inches%12;
return sprintf('%d ins', $inches);
}
echo cm2inches(162);
You will have result
3 ins

I want to decompose a time in two part, I mean by that, I want to take the left side and the right side, like a cut off right ?
22:02:00
23:00:00
23:12:00
Imagine those number, it doesn't matter if there's seconds or not, so we can kick them
22:02
23:00
23:12
Now, I to take the separate hour and minute. How can we do that ?
The simplest way would be to just cut out the first 5 characters of the string:
$time = '22:02:00';
echo substr($time, 0, 5); // 22:02
You can also parse the time using e.g. the DateTime class:
$time = '22:02:00';
$parsed = DateTime::createFromFormat('H:i:s', $time);
echo $parsed->format('H:i');
As Mark Baker commented, the strptime() function can also be used:
$time = '22:02:00';
$parsed = strptime($time, '%H:%M');
echo str_pad($parsed['tm_hour'], 2, '0', STR_PAD_LEFT) . ':' . str_pad($parsed['tm_min'], 2, '0', STR_PAD_LEFT);
Regular expressions would also work:
$time = '22:02:00';
preg_match('/^(?P<hour>\d{2}):(?P<minute>\d{2})/', $time, $result);
if (count($result) > 0) {
echo "{$result['hour']}:{$result['minute']}";
}

I want to know how I can randomize first and last two digits in php? Suppose the current code is:
FJA793HIYX
then after randomizing it should be:
HJA793HIGD
How can I do that?
Try
$str = 'HJA793HIGD';
$filter = substr($str,1,7);
echo $newstr= randLetter().$filter.randLetter().randLetter();
function randLetter() {
$int = rand(0,26);
$alpha = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
$rand_letter = $alpha[$int];
return $rand_letter;
}
Try this!
$randomDigit = substr( "123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ" ,mt_rand( 0 ,34 ) ,1 ) .substr( md5( time() ), 1)

How to solve this equation in php:
Ym = Zm * Zm+1 * Zm+2...Zm+n
Where,
Y = Unknown
m = array if numbers (1,2,3,4...)
z = array of numbers (8,6,9,10...). Number of elements of "Z" and "Y" array dependent from array "m".
For instance:
m = (1,2,3,4);
z = (5,6,10,7);
Y1=5*6*10*7
Y2=6*10*7
Y3=10*7
Y4=7
This equation was written by me. I think I've done something wrong while writing equation (Ym = Zm * Zm+1 * Zm+2...Zm+n). What I need is the example above.
Thanks!
Something in the lines of:
$m = array(0, 1, 2, 3);
$z = array(5, 6, 10, 7);
$Y = array(1, 1, 1, 1);
for ($x=0; $x<count($m); $x++) {
for ($w=$x; $w<count($m); $w++) {
$Y[$m[$x]]=$Y[$m[$x]]*$z[$w];
}
print "Y[{$m[$x]}]={$Y[$m[$x]]}\n\r";
}
Example http://sandbox.onlinephpfunctions.com/code/063e363111f4da275475c9c39dd8e7281083d22b
In functional programming language like Mathematia aka Wolfram language this would just be:
Y=FoldList[Times,1,{5,6,10,7}]
