mysql query is not fetching all the elements from the table - php

Question

it's just fetching the first element from the table.
Table name is categories which contains 2 columns : id, category
I cant understand why is it fetching just first row from the table.
<?php
$sql = "SELECT category FROM categories";
$result = mysql_query($sql);
$row = mysql_fetch_assoc($result);
//print_r($row);
?>

Answer 1

You need to iterate through the result set in order to retrieve all the rows.
while($row = mysql_fetch_assoc($result)) {
print($row);
}
Also, stop using mysql_ functions. They are no longer maintained and are officially deprecated. See the red box? Learn about prepared statements instead, and use PDO or MySQLi - this article will help you decide which.

Answer 2

Use this in while loop :
while ($row = mysql_fetch_assoc($result)) {
print_r($row);
}

Answer 3

Just like you wrote mysql_fetch_assoc($result); will get only one row. You have to use loop to get it all.

Answer 4

If you call mysql_fetch_assoc just once, you'll get only the first row...
while(false !== $row = mysql_fetch_assoc($result)) {
print_r($row)
}

Answer 5

The function you are using only does one record.
Try. ..while($row = mysqli_fetch_array($result))
{
echo $row['id'] . " " . $row['category'];
echo "";
}

Answer 6

For retrieve result set Use loop as per your need
foreach
Use when iterating through an array whose length is (or can be) unknown.
as
foreach($row as $val)
{
echo $val;
}
for
Use when iterating through an array whose length is set, or, when you need a counter.
for(i=0;i<sizeof($row);i++)
{
echo $row[$i];
}
while
Use when you're iterating through an array with the express purpose of finding, or triggering a certain flag.
while($row=mysqli_fetch_array($query))
{
echo $row['flag'];
}
