[SOLVED] foreach Loops

[RichieG]

Hi all...

 

I'm having a little problem understand the syntax for foreach loops, and the PHP manual isn't helping much, as it doesn't seem to be as descriptive as other pages in the manual.

 

foreach ($errmsg as $a) {
      echo $errmsg[$a] . "<br>\n";
    }

 

That's my code.  The $errmsg is an array which holds different strings depending on what errors were formulated from the code above it ($errmsg[$errmsgno++] = "Your password was not correct"; is the code for one of those.  It's executing the code once, but not echoing the message given.  Do I have the foreach wrong, or is the error elsewhere in my code?

 

TIA,

try this

<?php
foreach ($errmsg as $key => $val)
{
    echo $key . " = " . $val . "<br>\n";
}
?>

That was a quick reply 

 

Yes - that works.  Thanks a lot.

 

I'm still a little confused over the syntax of the loop, but there we go - as long as it's working!
