Number Series (1,2,3,4,5)

[RomanRemake]

Hi! I'm trying to use a php foreach tag count from 1 to 5 (I have 5 things listed).

 

E.g. Right now I have:

Dogs

Cats

Squirrels

Mice

Rats

 

What I want is (using php for each):

1. Dogs

2. Cats

3. Squirrels

4. Mice

5. Rats

 

Any suggestions?

Where is the data coming from, an array? A database? If a database is it stored in seperate fields, exploded from one field??? Please give more info...

If these are in an array, you can do this:

<?php
$things = array('Dogs','Cats','Squirrels','Mice','Rats');
echo '<ol><li>' . implode('</li><li>',$things) . '</li></ol>';
?>

I would suggest using a for() loop, or merge()+range()... but if you HAVE to use a foreach loop...

 

<?php
$array = array('Dogs', 'Cats', 'Squirrels', 'Mice', 'Rats');
$i = 1;
$newArray = array();

foreach($array as $element)
{
  $newArray[] = "$i. $element";
  ++$i;
}
?>

 

If you're using it to display in html, I would suggest the method above.

Using a foreach:

<?php
$things = array('Dogs','Cats','Squirrels','Mice','Rats');
$i = 1;
foreach($things as $element)
   echo $i++ . '. '. $element . '<br>';
?>

<?php
$array = array('Dogs', 'Cats', 'Squirrels', 'Mice', 'Rats');

for ($i = 0; $i < count($array); $i++){

$n = $i + 1;

echo $n . '.' . $array[$i] . '<br />';

}
?>

Personally I would do it that way...

If these are in an array, you can do this:

<?php
$things = array('Dogs','Cats','Squirrels','Mice','Rats');
echo '<ol><li>' . implode('</li><li>',$things) . '</li></ol>';
?>

Ooh, that is slick!

Another method using a foreach:

<?php
$things = array('Dogs','Cats','Squirrels','Mice','Rats');
foreach($things as $n => $element)
   echo ++$n . '. ' . $element . '<br>';
?>

Yeh I just tested it and it worked, but I dont get how imploding an array works :S

You'll have to put the items into an array, but you don't have to use foreach()... You could ues a simple for() like so:

 

<?php

$info[1] = "Dogs";
$info[2] = "Cats";
$info[3] = "Squirrels";
$info[4] = "Mice";
$info[5] = "Rats";

for($i = 1; $i <= count($info); $i++){
   echo "$i. $info[$i]"."<br>";
}

?>

 

Outputs:

 

1. Dogs

2. Cats

3. Squirrels

4. Mice

5. Rats

an array is all you can implode http://us.php.net/implode

for the record, we should be in the habit of running the count() function outside of the for() loop, otherwise the loop runs it on every iteration and wastes valuable DIGIRESOURCES!!

[RomanRemake]

Thank you for all of the replies (and so fast!).

 

Sorry for not clarifying. I'm pulling the info from a database. Here's the current code:

 

  <?php foreach($listings AS $listing):?>

  <?php echo $Routes->content($listing['Listing']['title'],$listing);?>

    <?php endforeach;?>

 

Take care,

RR

:s my bad, long time since I used implode/explode lol

[kenrbnsn]

You really shouldn't go in and out of php for each line. Do something like this:

<?php
$i = 1;
foreach($listings AS $listing)
     echo $i++ . '. ' . $Routes->content($listing['Listing']['title'],$listing) . '<br>';
?>

NOT THE DIGIRESOURCES!!!111oneleven

 

:s my bad, long time since I used implode/explode lol

 

but they're EXPLODE and IMPLODE... they're the coolest named functions in the language..

 

Of course they lose to fopen (phhhhopen!!!!) in the "most fun to say" category.

 

Yeah, I hold my own language awards where I give awards to the "most *" functions in the library... that doesn't make me weird, right?

 

.. I'll shut up now.
