PHP my code failed - php

Question

am i an idiot. 2 hours on something that seems to be simple and i don't get it.
I have an array like that:
Date | Surname
10/06/2016 Alex
10/06/2016 Marc
12/06/2016 John
12/06/2016 Steve
13/06/2016 Elliot
What i want is:
<div>
<div><h4>10/06/2016</h4></div>
<ul>
<li>Alex</li><li>Marc</li>
</ul>
</div>
<div>
<div><h4>12/06/2016</h4></div>
<ul>
<li>John</li><li>Steve</li>
</ul>
</div>
<div>
<div><h4>13/06/2016</h4></div>
<ul>
<li>Elliot</li>
</ul>
</div>
Here my failed code:
<?php
$dateShareHistoric = '';
$createShareHistoric = false;
foreach ($listFileShareHistoric as $tFilesShareHistoric) {
if($dateShareHistoric == $tFilesShareHistoric['dateShare'])
{
?>
<li rel="<?php echo $tFilesShareHistoric['idFiles']; ?>" data-uniqueid="<?php echo $tFilesShareHistoric['uniqueid']; ?>"><?php echo $tFilesShareHistoric['dateShare'] .' :: '. $tFilesShareHistoric['nomDonne']; ?></li>
<?php
}
else if($createShareHistoric){
$createShareHistoric = false;
?>
</ul></p></div>
<div class="callout callout-info"><h4><?php echo $tFilesShareHistoric['dateShare']; ?></h4><p><ul>
<li rel="<?php echo $tFilesShareHistoric['idFiles']; ?>" data-uniqueid="<?php echo $tFilesShareHistoric['uniqueid']; ?>"><?php echo $tFilesShareHistoric['dateShare'] .' :: '. $tFilesShareHistoric['nomDonne']; ?></li>
<?php
}
else{
$createShareHistoric = true;
?>
<div class="callout callout-info"><h4><?php echo $tFilesShareHistoric['dateShare']; ?></h4><p><ul>
<li rel="<?php echo $tFilesShareHistoric['idFiles']; ?>" data-uniqueid="<?php echo $tFilesShareHistoric['uniqueid']; ?>"><?php echo $tFilesShareHistoric['dateShare'] .' :: '. $tFilesShareHistoric['nomDonne']; ?></li>
<?php
}
$dateShareHistoric = $tFilesShareHistoric['dateShare'];
}
I feel ashamed to ask for that, sorry. If needed, i can post a picture of what it give to me. But it's logic, div, contain other div and other div...

Based on your php and output image I'm guessing that your array looks like this:
$data = [
[
'dateShare' => '10/06/2016',
'nomDonne' => 'Alex'
],
[
'dateShare' => '10/06/2016',
'nomDonne' => 'Marc'
],
[
'dateShare' => '12/06/2016',
'nomDonne' => 'John'
],
[
'dateShare' => '12/06/2016',
'nomDonne' => 'Steve'
],
[
'dateShare' => '13/06/2016',
'nomDonne' => 'Elliot'
]
];
In my opinion it would be best to transform given array and group items by dateShare which should make the rest easier
$groupedByDate = [];
foreach ($data as $item) {
$groupedByDate[$item['dateShare']][] = $item;
}
Now we can iterate given array and build a html that you needed
$html = '';
foreach ($groupedByDate as $date => $items) {
$html .= "<div><div><h4>{$date}</h4></div><ul>";
foreach ($items as $item) {
$html .= "<li>{$item['nomDonne']}</li>";
}
$html .= "</ul></div>\n";
}
echo $html;
Note that it does a lot of string concatenation but the end result is what you wanted:
<div><div><h4>10/06/2016</h4></div><ul><li>Alex</li><li>Marc</li></ul></div>
<div><div><h4>12/06/2016</h4></div><ul><li>John</li><li>Steve</li></ul></div>
<div><div><h4>13/06/2016</h4></div><ul><li>Elliot</li></ul></div>
