foreach loop in php

Question

$browsers = $day1;
foreach($browsers as $browser) 
{
 echo "<input type='checkbox'/>$browser";
}

When I use this code, it gives me output in single line, but I want to print two entries in single line and other in after the break.

Example:

1 2
3 4
5 6

Can anyone tell me how can we use a line-break in loop?

• Joseadrian: $browsers as $i => $browser and then use a condition for $i to break it
• Arda: Can you please be more spesific?
• Your Common Sense: Can you put your pencils on the table in groups by two? The algorithm is exactly the same
• Greg: @Joseadrian, that should be an answer. It would be the best one, but as a comment it might not be noticed.

Answer 1

If this is the output you want:

browser1 browser2
browser3 browser4
...
browserN-1 browserN

You could try this:

$bIndex = 0;
foreach($browsers as $browser) 
{
 echo "<input type='checkbox'/>$browser";
 if (($bIndex % 2) == 1) { // only true for odd bIndex values
 echo "<br>";
 }
 $bIndex++;
}

• gen_Eric: You could also do foreach($browsers as $bIndex => $browser) if it's a numerical array.

Answer 2

From what you're saying, I think you mean you want to have each checkbox and label on a new line.

foreach($browsers as $browser){
 echo '<p><input type="checkbox" /><label>'.$browser.'</label></p>';
}

Ofcourse, you'd want to be adding a name attribute on each the input tags (and the label tags), if you wanted to be able to process them on the server side.

Answer 3

If I got you correctly you want to show two in each line than after a break, try this

echo "<p>";
for($i=0;$i<count($browsers);$i++) {
if($i>0 && ($i%2==0)) { echo "</p><p>"; }
echo "<input type='checkbox' name='browser[".$browsers[$i]."]' /><label>".$browsers[$i]."</label>";
}
echo "</p>";

Edit for comment:

if it's not enumerated, still easy:

$i=0;
echo "<p>";
foreach ($browsers as $randomstuff=>$browser) { //or whatever array structure.
if($i>0 && ($i%2==0)) { echo "</p><p>"; }
echo "<input type='checkbox' name='browser[".$browsers."]' /><label>".$browsers."</label>";
$i++;
}
echo "</p>";

• Your Common Sense: what if $browsers is not enumerated list?
• Joseadrian: $kbrowser = array_keys($browsers); $browsers[$kbrowser[$i]]
• Arda: Updated the anser for the situations where it's not enumerated.
• joti: thanks can you tell me one more thing how can we submit the checked value in the database. because i want to submit the value of all checked in the database.
• Arda: Updated the code once again. After you submit, values will be sent as an array. e.g: For PHP, it'll be like $_POST['browser'] which will be an array, and with a foreach or for loop (like in the question or the examples) or with serializing you can process the data.
