Here is my simple code and i'm not able to understand why and how...
$len = 5; // total number of numbers
$min = 1; // minimum
$max = 90; // maximum
$range = array(); // initialize array
foreach (range(0, $len - 1) as $i) {
while(in_array($num = mt_rand($min, $max), $range));
//$range[] = $num;
list($br1, $br2, $br3, $br4, $br5) = $range;
}
print_r($range);
//echo $br1." ".$br2." ".$br3." ".$br4." ".$br5;
Hope in your help...! Thanks!
Should be written as:
<?php
$len = 5; // total number of numbers
$min = 1; // minimum
$max = 90; // maximum
$range = array(); // initialize array
foreach (range(0, $len - 1) as $i) { // you need to repeat the loop $len times
// get a new random number in the given range and assign it to $num,
// do it until the generated number is unique (not present in $range)
// the loop body is empty, as all the action happens inside its condition
while(in_array($num = mt_rand($min, $max), $range));
// append the random number to array
$range[] = $num;
}
list($br1, $br2, $br3, $br4, $br5) = $range;
echo $br1." ".$br2." ".$br3." ".$br4." ".$br5;
Demo.
The existing version of your code never updates $range variable (the corresponding line is commented out for some reason), that's why it doesn't work.
You need simple modification in your code.Your are assign list in side loop.But which is put out site of loop. And your variable range array are need commented
$len = 5; // total number of numbers
$min = 1; // minimum
$max = 90; // maximum
$range = array(); // initialize array
foreach (range(0, $len - 1) as $i) {
while(in_array($num = mt_rand($min, $max), $range));
$range[] = $num;
}
list($br1, $br2, $br3, $br4, $br5) = $range;
print_r($br1);
print_r($br2);
//echo $br1." ".$br2." ".$br3." ".$br4." ".$br5;
