spliting a string on specified tokens

dominant

I have a large string and i want to break it on (" ", " "). Both these conditions.

Is it practicable?

// $large_string already defined

$final_array = array();
$large_array = explode("<br>", $large_string);
foreach($large_array as $line){
    array_merge($final_array, explode(" ", $line));
}

The problem is that i want to re-unite the elements of the array after that double splitting.

It's just a parsing matter. So, when the parse finished i want the " " and the " " to go where there used to be.

A slight adaptaion from before ...

// $large_string already defined

$final_arrays = array();
$large_array = explode("<br>", $large_string);
foreach($large_array as $line){
    $final_arrays[] = explode(" ", $line);
}

Now you have an array of arrays.

To get the original back ...

foreach($final_arrays as $inner_array){
    $inner_strings[] = join(" ", $inner_array);
}
$new_large_string = join("<br>", $inner_strings);

There might be a quicker (more efficient) way to do this, but here, at least you can see what's going on.

not that there's anything wrong with the other code...

i think that when you join the array in " " everything is allright. But when you are about to join the second array with then the function doesn'r remember where the used to be. You are going to lost the position of the occurences.

Correct me if i am wrong.

I've just re-checked what I put earlier and it does work.
Really!!

Try it and see.

it worked really. Now i am going to make a parsing function
