echoing values from two different arrays alternating

[greenheart]

I have two, arrays one of titles one of descriptions. I want to echo the title in the first array followed by the first description in the second array, then echo the second title and the second description in the same way and so on up until the 10th value in each array.

 

Can someone kindly give me an example which I can use for this?

 

Thank you.

Depends on the structure of the data, providing both arrays are the same length and it's a non-associative array...

 

<?php
$titles = array("title 1", "title 2", "title 3");
$decriptions = array ("Blah... 1", "Blah... 2", "Blah... 3");

foreach($titles as $k=$title) {
   echo $title;
   echo $descriptions[$k];
}
?>

Hello

 

I get the error message

 

unexpected '='

 

from the line

 

foreach($titles as $k=$title) {

 

When I try the example you gave me.

With regards to the error, it should be => not just =

 

You could instead make use of the SPL (specifically the ArrayIterator and MultipleIterator) to loop over both arrays at the same time. For example:

 

<?php

$titles       = new ArrayIterator(array("title 1", "title 2", "title 3"));
$descriptions = new ArrayIterator(array("Blah... 1", "Blah... 2", "Blah... 3"));

// Use a MultipleIterator to iterate over our two arrays at the same time!
$mit = new MultipleIterator(MultipleIterator::MIT_KEYS_ASSOC);
$mit->attachIterator($titles, 'title');
$mit->attachIterator($descriptions, 'desc');

foreach ($mit as $it)
{
echo '<h1>' . $it['title'] . "</h1>\n";
echo '<p>' . $it['desc'] . "</p>\n\n";
}

?>

Thanks, that correction solves the error and it works! 

 

The ArrayIterator and MultipleIterator is a good tip for me, I'm going to be doing a fair bit of iterating over multiple arrays.

Btw, the error with my code was down to a typo, it should have been $k=>$title, this basically creates $k as the key of the array and $title as each value, I used that logic to fetch the item out of the other array with the same index.

 

Salthe's solution is possibly the 'bettter' solution though.
