Creating an array from a string separated by spaces

I have an input where a user may type in multiple words, and they are told to separate it with a space. So input may look like this:

foo

or like this:

foo bar php js

How can I check for spaces, and if there are spaces, split the words, then put it all into an array? I’ll loop through that array in my program. I’m just new to string handling like this.

Answer

See explode

// Example 1
$pizza  = "piece1 piece2 piece3 piece4 piece5 piece6";
$pieces = explode(" ", $pizza);
echo $pieces[0]; // piece1
echo $pieces[1]; // piece2
