split on Non-numeric character

[Anon]

$array = split(/\D/,$var);

In perl this code will split a variable on each non-numeric character in the variable.

$var = "12 13,15n20";
$array = split(/\D/,$var);

$array will look like this:
(12,13,15,20)

How can this be done in php?

Thanks,

the explode() function allows you to split a string into an array by a specified character or string.
For example...
$data = "I went to the park";

could be put through the explode() function to split the string by a " ".

$split = explode(" ", $data);

the $split array would look like this..
[0] => I
[1] => went
[2] => to
[3] => the
[4] => park

is that what you were trying to do?

Thanks,

yes, but I want to explode on any character that is non-numeric (0-9).

How to do that?

What you would have to do is replace any non-numeric character with a pipe charachter ("|"). Then explode that. The code to do this is below.

<?
$string = "32h14g15y34j98l78";
$length = strlen($string);
for($i=1;$i<=$length;$i++){
$temp = substr($string, $i, 1);
if (is_nan($temp)){
$string = str_replace($temp, "|", $string);
}
}
$array = explode("|", $string);
$arrayCount = count($array);
for($i=0;$i<$arrayCount;$i++){
echo $array[$i];
echo"<br>";
}
?>

This code is not tested but it is a solution to the problem

Hope this helps

thanks,

I am afraid I can't use the is_nan function as it is supported from version 4.2. My server is running 4.1... something

But i will work around this somehow.

Thanks a lot for the help!

I think this is what you are looking for:

$var = "12 13,15n20";
$array = preg_split("~\D~",$var);

And there you go 🙂
