php array iteration - unset

Question

Back to my original question, on how to check if the next elem starts with a space, if it does, concatenate it to the previous elem. how would you deal with cases where the array has multiple levels.

[1] => Array (
    [1] => Packages
    [2] => Sources
    [3] =>  Reading package
    [4] =>  Sources
    [5] =>  More Sources
    [6] => volatile Sources
    [7] =>  volatile
)

To output:

[2] => Array (
    [1] => Packages
    [2] => Sources Reading package Sources More Sources
    [6] => volatile Sources volatile
)

Will do it for the first space.

for($i = 0; $i < count($array); $i++){
    if($array[$i][0] == ' '){
        if($i > 0){
             $array[$i-1] .= $array[$i];
             unset($array[$i]);
        }
    }
}

What is your question? Iterating over an array and changing it is wrong! — Felix Kling

$t = array ( 'Packages',
             'Sources',
             ' Reading package',
             ' Sources',
             ' More Sources',
             'volatile Sources',
             ' volatile'
           );


$n = '';
foreach($t as $k => $v) {
    if (substr($v,0,1) == ' ') {
        $t[$n] .= $v;
        unset($t[$k]);
    } else {
        $n = $k;
    }
}

var_dump($t);

If you can be sure that a particular character (e.g. |) is not present in any of your elements, you can do something like this:

$array = explode('|',str_replace('| ',' ',implode('|',$array)));

Don't I at least get cool points for getting it all on one line?

This should work (untested) :

$size = count($array);
for($i = 0; $i < $size; $i++){
    $space = true;
    for($j = $i + 1; $j < $size && $space; $j++) {
        $space = $array[$j][0] == ' ';
        if($space){
             $array[$i] .= $array[$j];
             unset($array[$j]);
        }
    }
}
