Is this possible?

Is there a way to create a foreach( loop, whereby every 3rd value does something different. For example, I have a file called test.txt, that contains this:

 

a
b
c
d
e
f
g
h
i
j
k
l
m
n
o
p
q
r
s
t
u
v
w
x
y
z

 

Now, say I create a loop like:

 

<?php
$file = file_get_contents('test.txt');
$letter = explode('\n', $file);
foreach($letter as $loopletter){
echo ('<td>'.$loopletter.'</td>');
}
?>

 

Now, what if I wanted every third value to do this:

 

echo ('<td>'.$loopletter.'</td></tr><tr>');

;

 

Is this possible?

It is, but it looks as though you want to know so you can create tabular data in columns.  If so then there's loads of posts on here about it, just search these forums.

I just searched for that. Your post was the only one I found.

Many ways:

<?php
$file = file_get_contents('test.txt');
$letter = explode('\n', $file);
$tot = count($letter);
echo "<table><tr><td></td></tr>";
for($i=0;$i<$tot;$i+3){
   echo ('<tr><td>'.$letter[$i+1].'</td><td>'.$letter[$i+2].'</td><td>'.$letter[$i+2].'</td></tr>');
}
echo "</table>";
?>

Hug's is right, there's loads... There's even one in the phpfreaks tutorial section...

Do you want to output a table to screen, or actually output a doc? (.txt, .csv, .xls, etc.)

 

You can do either or both...

 

Simply use the strategy that rarebit employed: a simple counter that keeps track of every third event, but don't forget that you will have to put some closes clauses that add what is appropriate depending on the column count when the data runs out.

That's fine. Topic solved.

 

PS. Still can't find one :\

I know I asked that same question like a year ago so I know there's at least ONE thread on it... but I'm glad you got it to work... That's what's important.

@LemonInflux,

 

People are asking for additional information because many times what a poster is asking for is not really what they are wanting. So, by explaining what you are trying to accomplish will allow us to provide a best practice solution because the process you are asking to solve might not be the best.

 

But, a simple answer is something like this:

 

<?php

$step = 1;
foreach ($arrayVar as $value) {

  if ($step<3) {
    //Do this
    $step++;
  } else {
    //Do alternative
    $step = 1;
  }

}
