How would I use the PHP function preg_match() to test a string to see if any spaces exist?
"this sentence would be tested true for spaces"
"thisOneWouldTestFalse"
If you're interested in any white space (including tabs etc), use \s
if (preg_match("/\\s/", $myString)) {
// there are spaces
}
if you're just interested in spaces then you don't even need a regex:
if (strpos($myString, " ") !== false)
