PHP table appearance - php

Question

I wrote some code to display a html table with PHP.
It reads data from a file and checks whether the value is true or false.
The problem is the ugly appearance of the table at the end of the function:
True False
blue
Red
Red
blue
I would like to display the table like this:
True False
blue Red
blue Red
Also it displays the outcome before the function is finished c.q flush();
Here is the code:
?>
<table>
<tr>
<th>True</th>
<th>False</th>
</tr>
<?php foreach ($trimmed_array as $value) { ?>
<tr>
<?php if (check($value) == 0) { ?>
<td><?php print $value ?></td>
<td> </td>
<?php
} else { ?>
<td> </td>
<td><?php print $value ?></td>
<?php
}
sleep(1);
ob_flush();
flush();
} ?>
</table>
I realize this code outputs the table like the first example but I can`t seem to figure out how to change it to fit the second example?

Answer 1

Your code creates one table row per item in the array, so there will always be one blank column per row.
In the 'table' that you would like to display, the items in each row aren't related to each other.
So really you're creating 2 lists here, not a table as such.
I'd do something like this
<?php
$all_values = array('true' => array(), 'false' = array());
foreach($trimmed_array as $value){
if (check($value) == 0){
$all_values['true'][] = $value;
}else{
$all_values['false'][] = $value;
}
}
foreach($all_values as $name => $values){
?>
<ul class="<?php print $name;?>">
<?php
foreach($values as $value){
?>
<li><?php print $value; ?></li>
<?php
}
?>
</ul>
<?php
}
?>
You can then arrange your lists side by side with CSS

Answer 2

$true = array();
$false = array();
foreach ($trimmed_array as $value) {
if (check($value) == 0) {
$true[] = $value;
} else {
$false[] = $value;
}
}
for ($i = 0; $i < max(count($true), count($false)); $i++) {
echo '<tr>
<td>' . (isset($true[$i]) ? $true[$i] : '') . '</td>
<td>' . (isset($false[$i]) ? $false[$i] : '') . '</td>
</tr>';
}
