hello,

 

just one simple question

 

i have a variable that contains stuff like this:

 

$var = "cat - dog - fish"

 

i'd like to keep only the part between the first " - "

 

the result i'd want from the example above would be just "cat"

 

thanks!

/\b(.+) \-.+/

 

or if its just letters

 

/\b([a-Z]+) \- .+/

<?php

  $str = 'cat - dog - fish';
  $animal= explode('-',$str);
  
  $cat = trim($animal[0]);

?>

 

<?php

  $str = 'cat - dog - fish';
  preg_match('([aA-zZ]+) \-',$str, $animal);

  $cat = $animal[0];
?>

I like the explode better

Seems easier to understand what's going on to me.

 

<?php
$list = explode(" - ", $string);
$choice = $list[0];
?>
