I need to implement this method to my webpage. I want to echo the same sentence random times every time someone refresh my php webpage.
For example: Hello World!
You can do:
<?php
$min = 1; // Minimum 1 time
$max = 10; // Maximum 10 times
$string = "Hello world!\n"; // Print Hello World! and a new line
$x = rand($min,$max); // Make the random
$i = 0; // Set the iterator
do {
echo $string; // Echo the text
$i = $i + 1; // Increment the iterator
} while ($i < $x); // Test to make sure we didn't do it too many times
?>
This echos "Hello world!" anywhere from 1 to 10 times. You can search the PHP API to see how this works.

If i have a loop for example
for ($a=1; $a<6; $a++)
Is it possible to say for the first loop if another variable like $b is the same as one of the other numbers that will come like 2, 3, 4 or 5.
And what if i have a word split, so every letter is a variable like this:
$letter1 = str_split($word)[0];
$letter2 = str_split($word)[1];
$letter3 = str_split($word)[2];
$letter4 = str_split($word)[3];
$letter5 = str_split($word)[4];
How can i check if $a is at 1 in the loop,if it is not letter1 but letter2, 3, 4 or 5?
sure. Just check it against the counter:
for ($a=1; $a<6; $a++){
if ($a===$b){
echo ("b is caught!");
break;
}
}

I am trying to get a number between 1 to 6 with more chances to be close to 1.
i have tried this:
<li>{{Faker\Factory::create()->biasedNumberBetween($min = 10, $max = 20, $function = 'unbiased')}}</li>
What i am trying to do is to generate a number from 1 to 6 rand(1,6); but make the numbers be closer to one as the lower numbers will have more weight than the others.
Something like this ?
<?php
function weightedRand($min, $max, $weightedMax) {
$arr = array();
for($i = 0; $i < 10; $i++) {
$arr[] = rand($min, $weightedMax);
}
$arr[] = rand($min, $max);
return $arr[rand(0,10)];
}
echo weightedRand(1,6, 3);
?>
numbers below 4 will now be more likely than numbers above :)

Im trying to display 2 or more unique random results from a text file, How do I do that please?
But I need unique results and not 2 or more of the same.
Currently using this code, but it only returns 1 random result:
<?php
$text = file_get_contents('flatFileDB.txt');
$textArray = explode("\n", $text);
$randArrayIndexNum = array_rand($textArray);
$randPhrase = $textArray[$randArrayIndexNum];
?>
<?php echo $randPhrase ?>
I would use something like that
shuffle($textArray);
echo $textArray[0];
echo $textArray[1];
http://php.net/manual/tr/function.shuffle.php
You can give a shot to this also. Code is not tested. I am collecting the used into an array, and check, is that used before.
$text = file_get_contents('flatFileDB.txt');
$textArray = explode("\n", $text);
$used = array();
$countOfRandoms = 2;
$randoms = array();
$i = 1;
do {
if ($countOfRandoms == $i) {
break;
}
$randArrayIndexNum = array_rand($textArray);
if (in_array($randArrayIndexNum, $used)) {
continue;
}
$used[] = $randArrayIndexNum;
$random = $textArray[$randArrayIndexNum];
$i++;
} while (true);

I have long decimal numbers that I'd like to make easier to read. There's many 0's involved and I would like to bold the end of the string from where the numbers stop being just 0's. The number will always have 8 decimal places, no more, no less. It's worth noting that I would like any trailing zeros to also be bold, I don't just want to avoid bolding 0 as a whole.
Example:
Before - 0.00004320
After - 0.00004320
Any help or pointers in the right direction much appreciated.
Thanks.
You can do it using a loop and some string manipulation:
function doTheThing($number) {
$length = strlen($number);
$period = strpos($number, '.') + 1;
for ($i = $period; $i < $length; $i++) {
if ($number[$i] !== '0') {
$number = substr($number, 0, $i).'<b>'.substr($number, $i).'</b>';
break;
}
}
return $number;
}
echo doTheThing('0.00004320');
Or you can do it using a regular expression replacement:
function doTheThing($number) {
return preg_replace('/^(\d+\.0*)(\d+)$/', '$1<b>$2</b>', $number);
}
echo doTheThing('0.00004320');
echo doTheThing(sprintf('%.8f', 0.00004320)); // if your number is not a string
