Im trying to create an array with 100 random values from 1 to 1000, and multiply each by 4
so far I have:
$numbers = array(rand(1, 1000),rand(1, 1000),rand(1, 1000),
rand(1, 1000),rand(1, 1000),rand(1, 1000)
for($x=0; $x<100; $x++)
echo $numbers[$x]*4 . "<br/>";
How do I get rand(1,1000) to repeat 100 times without copy pasting? thanks!
<?php
$numbers = array();
for ($i = 0; $i < 100; $i++)
$numbers[] = rand(1, 1000);
foreach ($numbers as $number)
echo ($number * 4) . "<br />";
Have you tried this or I misunderstood your question:
$randArray=array();
for($x=0;$x<100,$x++)
{
$randArray[]=rand(1,1000)*4;
//echo $randArray[$x];
}
$numbers = array();
for ($x = 0; $x < 100; $x++) {
$numbers[] = rand(1,1000) * 4 . "<br>";
}
You could of course loop again if you need to have the values without them being multiplied by 4 for some reason.
Another possible solution without the inelegant loop:
array_map(function () { return rand(1,1000); }, range(1,1000));
<?php
$numbers = array();
for($i = 0; $i < 100; $i ++)
{
$numbers[] = rand(1, 1000);
echo $numbers[$i] * 4 . "<br/>\n";
}
?>
