Populating a table with changing variables

[TheServant]

Hey guys,
Basically I have a really big table with lots of variables all over the place.
eg.
[PHP]
<table>
<tr><td><?php echo( $var1." is ".$var2 ); ?></td></tr>
<tr><td><?php echo( $bar1." is ".$bar2 ); ?></td></tr>
<tr><td><?php echo( $dar1." is ".$dar2 ); ?></td></tr>
<tr><td><?php echo( $sar1." is ".$sar2 ); ?></td></tr>
...
[/PHP]

Now I want to do a for loop which will make the table for me echo-ing the <td> and <tr> aswell, however I want to change the variable name, so something like making an array:
[PHP]$array = array('var', 'bar', 'dar', 'sar');[/PHP]
And then having a for loop with something like:
[PHP]for ( i=0; name1=$array[i]; i++ ) {
echo( "<tr><td>".$nam e.1." is ".$name.2." </td></tr>" );
}[/PHP]

Firstly, is my for loop condition correct? Regardless, my main question is the echo line: How do you add a number (or characters) to the end of a variable name to change what variable it is? Can you?

There are several things that might be what you're after.

The foreach loop. This loops through each element of an array.
e.g.[PHP]$my_array=array ('cow','sheep', 'dog','cat');
foreach($my_arr ay as $element){
print "$element<b r>";
}[/PHP]That would print out:
cow
sheep
dog
cat

Another thing that might help you is variable variables. They are variables where the name of the variable can itself be a variable.

I would try to explain but I think this explanation is as good as any:

http://uk.php.net/manual/en/language.variables.variable.php

So you can do things like this:[PHP]$variable1='cow ';
$varaible2='she ep';
$varaible3='dog ';
$varaible4='cat ';

for($i=1; $<=4; $i++){
$variable_name= 'variable' . $i;
print $$variable_name ;
}[/PHP]
That's a totally useless example because you might as well have used an array, but you get the idea (I hope).

Cheers mate,
I think that is what I want. I will try it a bit later to make sure. Never used that $$variable way.

See for the use of these type of variables also markusn00b's article in the PHP article section titled Turn array indices into variables.
