Putting all parts of an array into one variable..

[Sesquipedalian]

Hey everyone,

 

What I'm curious of, is how do you put all parts of an array side by side into one variable?

 

What I mean is if you have

array('a', 'b', 'c', 'd')

how do you take it and put it into a variable, so the new variable ends up being

$var = 'abcd';

, where all of the array parts are next to eachother.

 

Appreciate your help!

$array = array('a', 'b', 'c', 'd');
$var = join('', $array); // $var contains: abcd

try something like this:

 

<?php

$array = array('a', 'b', 'c', 'd');

foreach($array as $letter){
$var .= $letter;
}

echo $var;

?>

thanks..

that answered my question.. but i realize it didn't help what i was trying to do.

 

I have a string full of parts that are seperated by |, so something like this:

 

$string = '| This | is | a | part | This | is | a | diff | part';

 

The string updates when i add to it (not manually), and so usually what i do to get the different parts is I use explode.

 

Now what I want to do is make it so that after every 4 array parts (like $string[1], $string[2], $string[3], $string[$4]) it to have a '<br />';

 

so that instead, $string would become 'This is a part <br />This is a diff <br />part'

 

How can I do that?

 

I want it to do it until it gets to the end of the array, so that I can have as much text as I want, and it will just make it like that.

 

I've tried different things, and I'm getting frustrated.. So.. how?

<?php
$parts = array('This','is','a','part','This','is','a','diff','part');

$slices = array();
$lines = ceil(count($parts)/4);
for($i = 0; $i < $lines; $i++)
{
$slices[] = array_slice($parts, $i*4, 4);
}
?>

 

Will split it into slices of up to four. Just join them like above again.
