getting the first word of a string

[etrader]

I want to catch the first word of a string in which the words are separated by "-" (e.g. "first-word-second-one-more"). I used this code:

$string = explode('-', $string);
echo $string[0];

 

The problem is that when the string contains only one word, it returns null  :-\

$catch=explode('-', $string);
If ($catch[0]!=null) { echo $catch[0]; } else { echo $string; }

No it doesn't.

 

$string = "word";
$string = explode('-', $string);
echo $string[0]; // word

You are quite right! It was my stupid mistake, as the problem has come from another issue  :-\ Sorry
