Handling PHP array of unknown size - php

Question

I have the following code that should select all the users in the relevant table in my database:
$hof = mysql_query("SELECT * FROM users");
$name = array();
$website = array();
$i=0;
while($result = mysql_fetch_array($hof)){
$name[$i] = $result['company'];
$website[$i] = $result['website'];
}
$i++;
I want to echo out the names and websites of all in the html section of my script (below the php) which will be a Hall of Frame of sorts. How would i do is? The fact that i do not know the size of the array deters me.
Usually, if i knew the size, i would so something like:
<?php echo $name[1];?>
<?php echo $name[2];?>
//and so on
Many thanks in advance. P.S. I plan to move across to MySQLi when i have the functionality of the website sorted first on localhost. Cheers

Answer 1

Your $i++; statement should be inside while loop
while($result = mysql_fetch_array($hof)){
$name[$i] = $result['company'];
$website[$i] = $result['website'];
$i++;
}
Better You do it like this,
$rows = array();
while($result = mysql_fetch_assoc($hof)){
$rows[] = $result;
}
and you echo them like this,
<?php
$len = count($name);
for($i=0;$i<$len;$i++){
echo $name[1];
}
?>
And for the alternative method use this,
<?php
foreach($rows as $row){
echo $row['name']; // use $row['website'] to echo website.
}
?>

Answer 2

foreach($name as $key=>$value){
echo $name[$key];
echo $website[$key];
}
Also there no need to take $i++, you can use following way
while($result = mysql_fetch_array($hof)){
$name[] = $result['company'];
$website[] = $result['website'];
}
See array in manual

Answer 3

First off the $i++ should be inside the loop.
To output them all, you could use implode(), or maybe foreach.

Answer 4

First, take your data into array
$data = array();
$sql = "SELECT * FROM users";
$res = mysql_query($sql) or trigger_error(mysql_error()."[$sql]");
while($row = mysql_fetch_array($res)){
$data[] = $row;
}
then use it anywhere you wish, say, in the template:
<ul>
<? foreach($data as $row): ?>
<li><?=$row['company']?></li>
<? endforeach ?>
</ul>

Answer 5

How about:
foreach ($name as $val)
{
echo $val;
}

Answer 6

you can use mysql_num_rows() to know the number of results returned by your query

Answer 7

$arrarySize = mysql_num_rows($hof);
