将值插入数组

Question

i have the following array

$block = array(
          **********,
          *****,
          **********,
          ***,
          ********);

Assuming max length of each array would be 10

I'm trying to insert new value in that array so my output would be as follows:

**********
*****00000
**********
***0000000
********00

So the following are my codes:

foreach($block as $key=>$newblock)
{
    $counter = 10 - strlen($newblock); 
    if ($counter > 0)
    {
      for($x=0; $x < $counter; $x++)
      {
          $block[$key] = implode("0",$newblock);
      }
    }
}

foreach($block as $x)
{
    print $x;
}

The codes seems not working..

Answer 1

Try this code

<?php
$block = array(
          '**********',
          '*****',
          '**********',
          '***',
          '********');

foreach($block as $key=>$newblock)
{
    $counter = 10 - strlen($newblock); 
    if ($counter > 0)
      for($x=0; $x < $counter; $x++)
          $block[$key] .= "0";
}

foreach($block as $x)
    print $x."<br/>";
?>

Output

**********
*****00000
**********
***0000000
********00

Answer 2

This is very simple, use function str_pad($input,$length,$pad_string) read more about str_pad()

<?php 
$block = array('**********','*****','**********','***','********'); 
foreach($block as $key=>$val)
{
    echo str_pad($val,10,"0");
    echo "</br>";
}
?>

This will Output :

**********
*****00000
**********
***0000000
********00
