Print result of an array in php list format

I have two arrays in php, which I compare and create a third and want to print this difference on a list.

I’ve tried the foreach, but this method prints a huge list in string.

This is my code:

$sql = mysqli_query($cx, "SELECT IPS FROM ipvalidos ORDER BY IPS ASC ");

while($aux = mysqli_fetch_assoc($sql)) {
    $arrayip[ ] = $aux["IPS"];
        }

$diferenca = array_diff($arrayip, $arraycompara);

foreach ($diferenca as $diferencas)
{
        $stringArrayF = $stringArrayF.$diferencas;
}       
echo $stringArrayF;

The printed result comes out:

192.168.0.1192.168.0.2192.168.0.3192.168.0.4192.168.0.5...

I wish I could put that result into one select html

<select><option value="$stringArrayF">$stringArrayF</option>;

<html>
$sql = mysqli_query($cx, "SELECT IPS FROM ipvalidos "); 






while($aux = mysqli_fetch_assoc($sql)) { 
	$arrayip[ ] = $aux["IPS"]; 
} 

$diferenca = array_diff($arrayip, $arraycompara); 

?> 




<body>
<select>
<?php	foreach ($diferenca as $diferencas) { 
	$stringArrayF = $stringArrayF.$diferencas; 
?> 

<option value="$diferencas"><?php echo $stringArrayF; ?></option> 

</body>


<?php } ?> 
</select>

Fixed kkk again , now go

It got better! But it stayed that way <select>
<option value="192.168.0.100">192.168.0.100</option> 
<option value="192.168.0.100192.168.0.104">192.168.0.100192.168.0.104</option> 
<option value="192.168.0.100192.168.0.104192.168.0.105">192.168.0.100192.168.0.104192.168.0.105</option> 
</select> The problem is separating the results of _ array_ by position.

declare that i = 0 , in which case we could in value exchange for an i++, type option value = $difca for option value = $i; i++ understood ?

I believe it has more to do with printing each position separately, I think the iteration, with a for wouldn’t do that in the <select> It would have to be somewhere else :/. I just don’t know where

Try to exchange your foreach for this code:

echo "<select>";
foreach ($diferenca as $value)
{
    echo '<option value="'.$value.'">'.$value.'</option>';
}       
echo "</select>";

Very good @Guilherme Corrêa Peralta! I had managed to make the list, but without the value . <select>
<?php
$sql = mysqli_query($cx, "SELECT IPS FROM ipvalidos WHERE RORDER BY IPS ASC");
 
 while($aux = mysqli_fetch_assoc($sql)) {
 $arrayip[ ] = $aux["IPS"];
 }

$diferenca = array_diff($arrayip, $arraycompara);

 
 $ipdisponiveis = implode("</option>\n<option>" , $diferenca);
 
?>

<option><?php echo $ipdisponiveis;?></option></select> His solution was Genial!

Make it fixed

$sql = mysqli_query($cx, "SELECT IPS FROM ipvalidos ORDER BY IPS ASC ");

while($aux = mysqli_fetch_assoc($sql)) {
    $arrayip[ ] = $aux["IPS"];
        }

$diferenca = array_diff($arrayip, $arraycompara);


?>

<?php


foreach ($diferenca as $diferencas)
{

$stringArrayF = $stringArrayF.$diferencas;
?>

<select><option value="<?php $stringArrayF ?>">$stringArrayF</option>;


<?php        
}    

?>

It’s coming up like this <html>
<form>

<select><option value="192.168.0.100">192.168.0.100</option>
<select><option value="192.168.0.100192.168.0.104">192.168.0.100192.168.0.104</option>
<select><option value="192.168.0.100192.168.0.104192.168.0.105">192.168.0.100192.168.0.104192.168.0.105</option>
<select><option value="192.168.0.100192.168.0.104192.168.0.105192.168.0.106">192.168.0.100192.168.0.104192.168.0.105192.168.0.106</option>

</form>

Fixed, just see the quotes ai, $sql = mysqli_query($Cx, "SELECT IPS FROM ipvalidos "); &#Xa while($aux = mysqli_fetch_assoc($sql)) { $arrayip[ ] = $aux["IPS"]; } $difca = array_diff($arrayip, $arraycompara); ? > <? php foreach ($differs from $differentials) { $stringArrayF = $stringArrayF. $differentials; ? > <select><option value="<? php echo $stringArrayF; ? >"></option></select> <? php } ?>

Unfortunately, it hasn’t changed much: <select><option value="192.168.0.100">192.168.0.100</option></select> 



<select><option value="192.168.0.100192.168.0.104">192.168.0.100192.168.0.104</option></select> 



<select><option value="192.168.0.100192.168.0.104192.168.0.105">192.168.0.100192.168.0.104192.168.0.105</option></select>

What I think the problem is in separating each position of the array into one <option> . I put the <select > at the beginning of everything and appeared only a combobox, but the result is not as it should be.

see la, fixed 2 kkk, pq actually, select has to this before for each, pq actually it was, multiplying the select

That we had already corrected. The foreach is doing an arithmetic progression look at Position 1; Position 1 + Position 2, Position 1 + Position 2 + Position 3 and so on! <select>
<option value="192.168.0.100">192.168.0.100</option>
<option value="192.168.0.100192.168.0.104">192.168.0.100192.168.0.104</option>
<option value="192.168.0.100192.168.0.104192.168.0.105">192.168.0.100192.168.0.104192.168.0.105</option>
</select>

You know @Victor, I don’t know if I made it clear, but there are 3 arrays . $diff = diff array_f($arrayip, $arraycompara). The $difference I turn into string with the foreach.

got that result <select>
<option value="192.168.0.10
192.168.0.100 
192.168.0.101 
192.168.0.102 
192.168.0.103 
192.168.0.104 
192.168.0.106 
192.168.0.107 
192.168.0.108 ..</option>
</select>
</form> with that code: while($aux = mysqli_fetch_assoc($sql)) {
 $arrayip[ ] = $aux["IPS"];
 }
 



$diferenca = array_diff($arrayip, $arraycompara);


 $ipdisponiveis = implode("\n", $diferenca);
 




?>
<select>


<option value="<?php echo $ipdisponiveis; ?>"><?php echo $ipdisponiveis; ?></option>


</select>
