How to randomize the columns in a selected row in PHP - php

Question

The selected id will select the row and randomize. However, it could randomize the same elements.
For example:
'I like to play the piano.'
The output I'm expecting is randomized to eg. ' Play the like to I piano '
But what I receives sometimes turns out to be ' I piano piano like to piano'
This words comes from the database(phpmyadmin). How do I make it such that the data will all appear but not repeat?
$strSQL = "SELECT * FROM sentences WHERE id
ORDER BY RAND() LIMIT 1;";
$x = rand(1,4);
echo "$x";
$y = rand(1,4);
echo "$y";
$z = rand(1,4);
echo "$z";
$c = rand(1,4);
echo "$c";
$rs = mysql_query($strSQL);
// Loop the recordset $rs
while($row = mysql_fetch_array($rs)) {
// Write the data of the person
echo "<dt>Sentence:</dt><dd>" . $row["$x"] . " " . $row["$y"] . " " . $row["$z"] . " " . $row["$c"] ."</dd>";
}

Answer 1

You can do:
//create an array with numbers 1-4
$order = array(1,2,3,4);
//shuffle them in random order
shuffle($order);
$rs = mysql_query($strSQL);
// Loop the recordset $rs
while($row = mysql_fetch_array($rs)) {
// Write the data of the person
//Display all the array values from 0-3 (array index starts from 0)
echo "<dt>Sentence:</dt><dd>" . $row[$order[0]] . " " . $row[$order[1]] . " " . $row[$order[2]] . " " . $row[$order[3]] ."</dd>";
}
Note:
Please, don't use mysql_* functions in new code. They are no longer maintained and are officially deprecated.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. If you choose PDO, here is a good tutorial.

Answer 2

Try using the shuffle() function.
$strSQL = "SELECT * FROM sentences WHERE id
ORDER BY RAND() LIMIT 1;";
// Loop the recordset $rs
while($row = mysql_fetch_array($rs)) {
shuffle($row);
// Write the data of the person
echo "<dt>Sentence:</dt><dd>" . implode(' ', $row) . "</dd>";
}
Unrelated: mysql_* are deprecated as of php 5.5 and will be removed in the future. Use mysqli or PDO instead.
