Split() function creates weird values

[ringostizar]

When I run the split() function, I get an array that doesn't go from 0-x but I get mixed up values from 0,2,4,5 ... etc. Here's my script:

$text = "vtk - xtn fac";
$text = str_replace("-", " to ", $text);
$pieces = split('[/.-]|[[:space:]]', $text);
for ($m=0; $m<sizeof($pieces); $m++) {
	if (empty($pieces[$m])) {
		unset($pieces[$m]);
	}
}
print_r($pieces);

My result is: Array ( [0] => vtk [2] => to [4] => xtn [5] => fac )

You see, the order jumps like this: 0,2,4,5. How do I get my array to reset to 0,1,2,3? Thank you all.

you unset some elements of the array after split. that is why some indexes are skipped over.

This should do it.

$text = "vtk - xtn fac";
$text = str_replace("-", "to", $text);
$pieces = explode(" ", $text);
print_r($pieces);

Hi and thanks for the tips, but the reason I am scripting the way that I am is that I need to remove elements of my array that are empty. Doing this results in an unordered index array. How can I reset my indexes to read 0,1,2,3?

use the explode function.

$text = "vtk - xtn fac";
$text = str_replace("-", " to ", $text); 
$text = explode(" ",$text);

echo "<pre>";
print_r($text);
echo "</pre>";
