Variables.. Loop??

[Derick88]

Hello,
I would like to know if I could use this script more compact except to write all the variables.. Like a while function..

Thanks

$ta1 = $b1+1;
$ta2 = $b2+1;
$ta3 = $b3+1;
$ta4 = $b4+1;
$ta5 = $b5+1;
$ta6 = $b6+1;
$ta7 = $b7+1;
.........
......
...

Why not store them in an array?

EDIT

or you could do the following, although, it doesn't do much for code readability;

for($x=0;$x<8;$x++){

${"ta" . $x} = ${"b" . $x} + 1;

}

// With array example below

$b[1] = 0;
$b[2] = 0;
$b[3] = 0;
$b[4] = 0;
$b[5] = 0;
$b[6] = 0;
$b[7] = 0;

$ta = array();

foreach($t as $key => $value){
	$ta[$key] = $b[$key] + 1;
}

Because I don't know anything about array....
Thanks for the script!

[Derick88]

It look more compact with for()
Thanks

Because I don't know anything about array....

And you dont know anything about variable variables either (the technique used in dougal85's example), so it does not hurt to learn arrays.

[dougal85]

and arrays are far more versatile!

And once you've learnt about arrays, look into array_map().

Here's a quick spike:

/**
 * Add 1 to $int
 *
 * @param int $int
 * @return int
 */
function increment($int)
{
	return $int + 1;
}

// initialise test array
$b=array_fill(0,10,rand(1,100));

// apply increment to each value of $b and save to $ta
$ta = array_map('increment',$b);

// Test results 

// old vals
echo '<h2>Old values</h2>';
echo '<em>Randomly generated numbers filled initial array</em>';
echo '<pre>';
print_r($b);
echo '</pre>';

// new vals
echo '<hr />';
echo '<h2>New values</h2>';
echo '<em>Randomly generated numbers in initial array should be incremented by 1</em>';
echo '<pre>';
print_r($ta);
echo '</pre>';
echo '<hr />';
