Question

I would like to know how I could find out in PHP if a variable only contains 1 word. It should be able to recognise: “foo” “1326” “;394aa”, etc.

It would be something like this:

$txt = "oneword";

if($txt == 1 word){ do.this; }else{ do.that; }

Thanks.

I’m assuming a word is defined as any string delimited by one space symbol

$txt = "multiple words";

if(strpos(trim($txt), ' ') !== false)
{
    // multiple words
}
else
{
    // one word
}
