I'm doing a quiz, and I saved the answers in an array, I want those answers to appear randomly that does not repeat in the quiz.
I used the following code.
<?php
$times = array('', 'Corinthians', 'Santos', 'Flamengo');
for ($i = 0; $i < 3; $i++) {
$rand = array_rand($times, 2);
?>
<div>
<input type="radio" name="quiz1" value="A">
<label for="questao1-A"><?php echo $times[$rand[1]]; ?></label>
</div>
<?php } ?>
You're using the wrong feature.
shuffle exists for this, see the manual at link .
The shuffle just causes the array to be randomized, so the defined order is ignored, including the indices!
The simplest way to solve what you want is, exactly:
PHP:
<?php
$times = array('', 'Corinthians', 'Santos', 'Flamengo');
shuffle($times);
foreach($times as $time){
?>
<div>
<input type="radio" name="quiz1" value="A">
<label for="questao1-A"><?= $time ?></label>
</div>
<?php } ?>
Result:
<div>
<input type="radio" name="quiz1" value="A">
<label for="questao1-A"></label>
</div>
<div>
<input type="radio" name="quiz1" value="A">
<label for="questao1-A">Flamengo</label>
</div>
<div>
<input type="radio" name="quiz1" value="A">
<label for="questao1-A">Corinthians</label>
</div>
<div>
<input type="radio" name="quiz1" value="A">
<label for="questao1-A">Santos</label>
</div>
Note: Changing to
foreachis optional, but for me it improves reading code and reduces the countless uses of[]next to the parameter, which can confuse.
