    foreach statements - can you help?

    Hi all

    I cant itterate through an array! Why doesn't this code work?

    <html>
    <title> Hello World Script </title>
    <body>
    <?php
    $Name="Joe Blogg";
    $a=a;
    $b=b;
    $rabbit[0]="Test";
    $rabbit[1]="The";
    $rabbit[2]="Array";

    echo "Hello World";

    echo "<p> My name is "."$Name </p>";

    echo $a." ".$b;

    echo "$rabbit[0] $rabbit[1] $rabbit[2]";

    echo "<p>";

    for ($i=1;$i<13;$i+ +)
    {
    echo "\n Multiply by $i : ";
    echo "<p>";
    for($e=1;$e<13; $e++)
    {
    $result = $i * $e;
    echo "$i x $e = $i * $e";
    echo "<p>";
    }
    }

    /* for(p=0;p<3;p++ )
    {
    echo $rabbit[$p];
    }
    */

    foreach($k as $rabbit);
    {
    echo "$k";
    }

    ?>
    </body>
    </html>

      In your first (commented out) iteration of $rabbit, you left out the $
      symbol in the for() statement. for(p=0;p<3;p++ ) should be
      for($p=0;$p<3;$ p++).

      In your second iteration (the foreach() one), you gave the foreach()
      "parameters " in the wrong order. It should be foreach($rabbit as $k). Also,
      take away the semicolon at the end of that line.

          Figuring out what arguments functions expect makes coding unnecessarily
          difficult. That's why there's a manual that explains it ;-)
