PHP mySQL get table headers function - php

Question

I'm trying to build a PHP function that allows me to have an array of the headers of MySQL database for finding a particular field.
function table($tablename,$id) {
$post = mysql_query("SELECT * FROM $tablename WHERE ID = '$id'");
}
How would I then output the table headers as effective miniature queries for the row in question.
eg. $post->title, $post->timestamp, $post->field4

Answer 1

You need MySQLi or PDO_MySQL, but in your case:
while ($row = mysql_fetch_assoc($post)) {
echo $row['title'];
}
Documentation
Remember that the use of mysql_* function is discouraged.

Answer 2

A simple PHP Script to fetch the field names in MySQL:
<?php
$sql = "SELECT * FROM table_name;";
$result = mysql_query($sql);
$i = 0;
while($i<mysql_num_fields($result))
{
$meta=mysql_fetch_field($result,$i);
echo $i.".".$meta->name."<br />";
$i++;
}
?>
OUTPUT:
0.id
1.todo
2.due date
3.priority
4.type
5.status
6.notes
Hope this helps! Taken from php.net documentation.

Answer 3

How about mysql_fetch_assoc($post)?
To get all field names int a seperate array:
$post = mysql_fetch_assoc($post);
$fields = array();
foreach($post as $title => $value){
$fields[] = $title;
}
You can use this in a while loop to go through all rows and get theri field values(as well as their names):
while($p = mysql_fetch_assoc($post)){
$title = $p['title'];
$timestamp = $p['timestamp'];
//And so on...
}
Edit: And Pierpaolo is right, you should use another mysql implementation as the old one is gonna be removed in PHP 5.5/5.6 or a bit later...

You can get just the column names by executing this:
DESCRIBE `MyTable`;
It will return a result set that contains Field, Type, Key, etc.
$query = mysql_query("DESCRIBE `MyTable`");
while($result = mysql_fetch_assoc($query)) {
echo $result['Field'] . "\n";
}
