PS the output from my changes i tried above can be viewed here: http://culmstocklights.com/bingo-dev.php as you can see it simply creates extra rows with sequesnced numbers 

 

this is generated byu the following code: 

<?php
	/*
		Random bingo Generator - by Shane Nelson
	*/

	DEFINE('BR', "<br />\n");
	
	$number_of_cards = 6; // the amount of unique cards to generate. don't make too many!

	$columns = array(
		range(1,9),
		range(10,19),
		range(20,29),
		range(30,39),
		range(40,49),
		range(50,59),
		range(60,69),
		range(70,79),
		range(80,89),
		range(90,99)
	);

	$bingo_cards = array();
	$card_hashes = array();
	$i = 0;
	
	/* GENERATE THE CARDS */
	while($i < $number_of_cards) {
		$bingo_card = array();

		for($j=0; $j<5; $j++) {
			$random_keys = array_rand($columns[$j], 9);
			$random_values = array_intersect_key($columns[$j], array_flip($random_keys)); // http://stackoverflow.com/a/18047331/3625228
			$bingo_card = array_merge($bingo_card, $random_values);
		}

		// generate a unique hash for this card and compare it to the ones we already have
		$card_hash = md5(json_encode($bingo_card)); // or whatever hashing algorithm is preferred

		if(!in_array($card_hash, $card_hashes)) {
			$bingo_cards[] = $bingo_card;
			$card_hashes[] = $card_hash;
			$i += 1;
		}

		if($i > 10000) break; // safety exit
	}

	/* OUTPUT, if needed (output with monospace font). could be made into an html table. */
	foreach($bingo_cards as $card) {
		for($k=0; $k<(sizeof($card)/5); $k++) {
			echo(str_pad($card[$k], 2, ' ', STR_PAD_LEFT).' | ');
			echo($card[$k+5].' | ');
			echo($card[$k+10].' | ');
			echo($card[$k+15].' | ');
			echo($card[$k+20].BR);
			if($k < 4) echo(str_repeat('-', 22).BR);
		}
		echo(BR.BR);
	}

?>

gw1500se, thank you for your repsonse - i was hoping that given the non commecial - comunity nature of this request that your answer may have been a little more charitable, im a complete beginner to PHP so really dont understand the code. That said i have tried what you suggested already I spotted the: 

$columns = array(
		range(1,15),
		range(16,30),
		range(31,45),
		range(46,60),
		range(61,90)
	);

part and expanded this to 9 'ranges' with the number outputs i was looking for i then changed 

$random_keys = array_rand($columns[$j], 5);

to 

$random_keys = array_rand($columns[$j], 9);

hoping that would solve my problem however the output didnt match my expecations i suspect thats becuase the output is driven from here: 

foreach($bingo_cards as $card) {
		for($k=0; $k<(sizeof($card)/5); $k++) {
			echo(str_pad($card[$k], 2, ' ', STR_PAD_LEFT).' | ');
			echo($card[$k+5].' | ');
			echo($card[$k+10].' | ');
			echo($card[$k+15].' | ');
			echo($card[$k+20].BR);
			if($k < 4) echo(str_repeat('-', 22).BR);
		}
		echo(BR.BR);

however thats so far away from my basic HTML knowledge that i cant even begin to see what i might change here to fix it!

Hi All, im a beginner so please bear with me - as part of teh COVID-19 response we have been running a little free bingo night for our local village the numbers are called on facebook live on a saturday night and the village join in for a bit of fun, its taken off well and were finding that issuing the tickets is taking all day so were trying to simplify it - Ive got half way there with a peice of code i found online - but i cant quite get 'the whole way'! Wouldbe greatful if someone could helpo with a few issues! 

<?php


	DEFINE('BR', "<br />\n");
	
	$number_of_cards = 6; // the amount of unique cards to generate. don't make too many!

	$columns = array(
		range(1,15),
		range(16,30),
		range(31,45),
		range(46,60),
		range(61,90)
	);

	$bingo_cards = array();
	$card_hashes = array();
	$i = 0;
	
	/* GENERATE THE CARDS */
	while($i < $number_of_cards) {
		$bingo_card = array();

		for($j=0; $j<5; $j++) {
			$random_keys = array_rand($columns[$j], 5);
			$random_values = array_intersect_key($columns[$j], array_flip($random_keys)); // http://stackoverflow.com/a/18047331/3625228
			$bingo_card = array_merge($bingo_card, $random_values);
		}

		// generate a unique hash for this card and compare it to the ones we already have
		$card_hash = md5(json_encode($bingo_card)); // or whatever hashing algorithm is preferred

		if(!in_array($card_hash, $card_hashes)) {
			$bingo_cards[] = $bingo_card;
			$card_hashes[] = $card_hash;
			$i += 1;
		}

		if($i > 10000) break; // safety exit
	}

	/* OUTPUT, if needed (output with monospace font). could be made into an html table. */
	foreach($bingo_cards as $card) {
		for($k=0; $k<(sizeof($card)/5); $k++) {
			echo(str_pad($card[$k], 2, ' ', STR_PAD_LEFT).' | ');
			echo($card[$k+5].' | ');
			echo($card[$k+10].' | ');
			echo($card[$k+15].' | ');
			echo($card[$k+20].BR);
			if($k < 4) echo(str_repeat('-', 22).BR);
		}
		echo(BR.BR);
	}

?>

This code does what i need - sort of but creates a grid / table /array (?) thats 5 rows / 5 columns - what i would like to do is replciate (as close as possible) the tickets we have been sending out for the last few weeks 

these are 3 rows per ticket and 9 columns with the numbers 1-9 in C1, 10-19 in C2, 20-29 in c3 etc tec this makes it easy for older users to find the numbers while they are been called - see example below 

So far ive achieved this: http://culmstocklights.com/bingo.php each user visiting the page is presented with 3 Games (Green Pink and Brown) and 6 sets of numbers in each game (thats how we do it at the moment) 

Im 75% of the way there just need to get this to 3 rows and 9 columns per game and if possible randomly add the blanks. 

Any help would be massivly appreciated! Thanks in advance
