Checking for blank spaces

[micmac]

Hi again,
Can anyone tell me the best way to determine whether a value has a blank space in it?
For example:
word1,word2,word3 - this is correct
word1, word2, word3 - this is incorrect

I've looked at ctype_space but have been told is unreliable.
Any ideas?

Cheers,
micmac

Hi

Using regexp for sure !
If just you want to detect if your sentence is incorrect try :

$sent = "word1, word2, word3";
$bool = ereg(",[ ]*", $sent);

Better, if you want to remove these optionnal extra blank:

$sent = "word1, word2, word3";
$sent = ereg_replace(",[ ]*", ",", $sent);
echo($sent);

A bit overboard, bobio! If it's just a matter of seeing if there is a space character in the string strpos($text,' ')!==false is plenty sufficient.

If by "space" is meant any whitespace character (as per ctype_space), then preg_match('/\s/',$text) tests, and preg_replace('/\s/','',$text) removes.

ok and by the way I was thinking about sentences instaed of words...

In that case you should match '/,\s/'

huhuhu 😉
