list --
Assign variables as if they were an array
Description
void
list ( mixed ...)
Like array(), this is not really a function,
but a language construct. list() is used to
assign a list of variables in one operation.
Note:
list() only works on numerical arrays and assumes
the numerical indices start at 0.
Example 1. list() examples <?php
$info = array('coffee', 'brown', 'caffeine');
// Listing all the variables
list($drink, $color, $power) = $info;
print "$drink is $color and $power makes it special.\n";
// Listing some of them
list($drink, , $power) = $info;
print "$drink has $power.\n";
// Or let's skip to only the third one
list( , , $power) = $info;
print "I need $power!\n";
?> |

Example 2. An example use of list() <table>
<tr>
<th>Employee name</th>
<th>Salary</th>
</tr>
<?php
$result = mysql_query ("SELECT id, name, salary FROM employees",$conn);
while (list ($id, $name, $salary) = mysql_fetch_row ($result)) {
print (" <tr>\n".
" <td><a href=\"info.php?id=$id\">$name</a></td>\n".
" <td>$salary</td>\n".
" </tr>\n");
}
?>
</table> |
