Question

I have sentence table :

======================================================================
|  id_row  |  id_document |   id_sentence   |       sentence         | 
======================================================================
|     1    |       1      |       0         | Example sentences A    |
|     2    |       1      |       1         | Example sentences B    |
|     3    |       2      |       0         | Example sentences C    |
|     4    |       2      |       1         | Example sentences D    |
======================================================================

I wanna merge sentence that have same id_document into array like => Array( [1] => Array ( [0] => Example sentences A [1] => Example sentences B ) [2] => Array ( [0] => Example sentences C [1] => Example sentences D ))

Here’s the code :

<?php
require_once 'conf.php';
$sql = mysql_query('SELECT sentence FROM sentence group by id_document') or die(mysql_error());
while ($row = mysql_fetch_array($sql)) {
    $sentence[] = $row['sentence'];
}
print_r($sentence);
?>

but, I just get one sentence in every different id_document. Help me. Thank you 🙂

Answer 1

Index the array on id_document, and add new entries to the array like this:

while ($row = mysql_fetch_array($sql)) {
    $sentence[ $row['id_document'] ][] = $row['sentence'];
}
