Expression to check for the absence of a period?

[blurredvision]

I haven't quite learned expressions yet, so I was hoping somebody could quickly give me the right to code to check a variable for the absence of a period.  Thanks!

No expression required...

 

<?php

$string = "This has a full stop.";
if(!strpos($string, ".")){
echo "No fullstop!";
}else{
echo "Full stop is present!";
}

?>

Well, if shes is pre-menopausal and not married yet then I would say shock.

No no no no Strpos returns an in, which can be 0... if $string = '.somestring', your if statement willl return true. Use this instead

 

<?php

$string = "This has a full stop.";
if( strpos($string, ".") === FALSE ){
echo "No fullstop!";
}else{
echo "Full stop is present!";
}

?>
