PHP: For each different key value, group together - php

Question

I have this mysql sample table:
+----+---------------+-------+
| id | company | value |
+----+---------------+-------+
| 1 | google | 50 |
+----+---------------+-------+
| 2 | microsoft | 24 |
+----+---------------+-------+
| 3 | google | 12 |
+----+---------------+-------+
| 4 | microsoft | 89 |
+----+---------------+-------+
| 5 | stackoverflow | 45 |
+----+---------------+-------+
And I want to print it as such so that they are grouped by company:
<ul class="google">
<li>50</li>
<li>12</li>
</ul>
<ul class="microsoft">
<li>24</li>
<li>89</li>
</ul>
<ul class="stackoveflow">
<li>45</li>
</ul>
This is my current code:
$resultx = mysql_query();
$temp=0;
$p = array();
while ($row = mysql_fetch_array($resultx)) {
$p[$temp]['id']=$row['id'];
$p[$temp]['company']=$row['company'];
$p[$temp]['value']=$row['value'];
$temp++;
}
foreach ($p as $obj) {
echo '<ul class="'.$obj["company"].'"><li>'.$obj["value"].'</li></ul>';
};
But my code prints all the company together.
EDIT:
I want to group the company in different UL's.
I would assume that I would have to use another foreach inside my foreach.

Answer 1

When building your array, make the key of the array be the company name or company id. Since I don't see a company id in your query, I will go with name. Now have it be a multidemsional array, with the inner array beging the values.
$resultx = mysql_query();
$p = array();
while ($row = mysql_fetch_array($resultx)) {
$p[$row['company']]['id']=$row['id'];
$p[$row['company']]['company']=$row['company'];
$p[$row['company']]['values'][]=$row['value'];
}
foreach ($p as $obj) {
echo '<ul class="'.htmlspecialchars($obj["company"]).'">';
foreach ($obj['values'] as $value) {
echo '<li>'.htmlspecialchars($value).'</ul>';
}
echo '</ul>';
};

Answer 2

Let us begin:
SELECT * FROM `yourTableName` ORDER BY `company`
Then you do this:
for($i = 0; $i<sizeOf($p); $i++)
{
if ($p[$i] == 0 || $p[$i]['company'] != $p[$i-1]['company'])
echo '<ul class="'.$obj["company"].'">';
ecoh '<li>'.$obj["value"].'</li>';
if ($p[$i] == 0 || $p[$i]['company'] != $p[$i-1]['company'])
echo '</ul>';
}

Answer 3

$resultx = mysql_query();
$temp=0;
$companies = array();
while ($row = mysql_fetch_array($resultx)) {
$companies[$row['company']][]=$row;
}
foreach ($companies as $company=>$values) {
echo '<ul class="'.$company.'">';
foreach($values as $value){
echo '<li>'.$value["value"].'</li>';
}
echo'</ul>';
}
There are of course other ways to do it, to make it simple I used 2 different loops.

Answer 4

$companies = array();
//One array that will have companies' names as keys
// and the value would be an array of values.
$resultx = mysql_query();
while ($row = mysql_fetch_array($resultx)) {
$companies[ $row['company'] ][] = $row['value'];
}
foreach ($companies as $company => $values) { //Loop the companies
echo '<ul class="'.$company.'">';
foreach($values as $value) //Loop the values of that company
{
echo '<li>'.$value.'</li>';
}
echo '</ul>';
}
** Haven't tested it.

Answer 5

I hope that this will solve your problem
$p = array(array());
while ($row = mysql_fetch_array($resultx)) {
$p[$row['company']][] = $row['value'];
}
foreach ($p as $key => $obj) {
echo '<ul class="'.$key.'">';
foreach ($obj as $val) {
echo '<li>'.$val.'</li>';
}
echo '</ul>';
};
