Split a string in half by a delimiting character

I am trying to split a string in PHP however it's not as easy as it is in C#, it seems to be a tad bit messy...

I have a string, which looks something like this:

blahblah1323r8b|7.45

and I would like to be able to access the results of the split like this:

$var = split_result['leftside'];
$var = split_result['rightside'];

Is this easy to do in PHP? I'm trying to find some good examples, but the ones I've seen seem to be not what I'm trying to do, and are a little over complicated.

Solution

  • PHP has adopted a C language function sscanf() for parsing a predictably formatted string AND it has the capability of casting the numeric values as integer/float types (which explode() can't do by itself).

    A few implemenations depending on your needs: (Demo)

    1. return an array:

      var_export(
    sscanf($str, '%[^|]|%f')
);

      output:

      array (
  0 => 'blahblah1323r8b',
  1 => 7.45,
)

    2. create individual variables:

      sscanf($str, '%[^|]|%f', $left, $right);
var_dump($left, $right);

      output:

      string(15) "blahblah1323r8b"
float(7.45)

    3. create an associative array:

      [$key, $result[$key]] = sscanf($str, '%[^|]|%f');
var_export($result);

      output:

      array (
  'blahblah1323r8b' => 7.45,
)
