[RESOLVED] foreach()! FOREACH()! AAAAAAAARGHHH!

dek

this is the kind of problem which really wants to make me smash my powerbook on the wall.

so, I have created an array by means of multiple checkboxes. I know it's a valid array because print_r() returns something like:

Array ( [0] => 1 [1] => 2 [2] => 6 [3] => 17 )

so now I simply want to loop through the array and display the values. that should be easy enough using following code:

// create array
$a = array(1, 2, 6, 17);

// loop through array		
foreach ($a as $v) {
  echo 'Current value of '.$a.': '.$v.'';
}

BUT IT DOES NOT WORK!!!!

I keep getting a parse error along the lines of:

Parse error: syntax error, unexpected T_ECHO in /home/.ivanhoe/localprojects/localprojects.net/db/projects.php on line 138

where line 138 would be: echo 'Current value of '.$a.': '.$v.'';

I've dumbed down the code to a minimum, well, actually I've copypasted above code from php.net. my php installation is 4.4.2, so that shouldn't be the problem.

Someone got a hint where the error might be? or is it something obvious and I'm just plain stupid?

This error is not duplicated using the sample code provided.

Current value of Array: 1Current value of Array: 2Current value of Array: 6Current value of Array: 17

If I had to guess, I would say you are missing either a ; or } somewhere before line 138.

how about this?

// create array
$a = array(1, 2, 6, 17);

// loop through array

foreach ($a as $v) {
echo "Current value of the array is: $v";
}

Drakla

// loop through array        

foreach ($a as $k => $v) {
  echo 'Current value of $a['.$k.']: '.$v.'<br />';
}

is probably more like what you mean

thanks for all your suggestions!

finally it works! the most frustrating thing isn't that I lost a couple of hours trying to find the error, but rather that I have no idea what I changed to make it work. I was just copypasting some of your solutions, changing some variable names and bang... it worked.

I have the feeling, it might have something to do with a hidden symbol of some sort. I once spent a whole day trying to find a coding-error (though, that wasn't php), until I finally turned on hidden characters and found out, that a portion of copypasted code was using different line breaks as the rest of the code! WTF!

but maybe it's something completely different or the mightay php coding god is having a bad day and just wanted to mess around a little.

anyway. as unsatisfying as it may be, I'm calling it resolved...
