Creating an array from a string separated by spaces

Question

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 1

See explode

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

Answer 2

Yes explode will do every thing for you and foreach can be used to retrieve the values from the array again. Your complete code will be something like following one:

$str = "foo bar php js"; $arr =  explode(" ", $str);  //print all the value which are in the array foreach($arr as $v){     echo $v; } 

Hope this will help you.
