guyfromfl Posted August 4, 2011 Share Posted August 4, 2011 I am trying to create a loop that increments by .5 This just runs forever: for ($bathrooms=0; $bathrooms<=8; $bathrooms = $bathrooms + .5) { echo "<option value=\"$bathrooms\">$bathrooms</option>\n"; } Any ideas?

guyfromfl Posted August 4, 2011 Author Share Posted August 4, 2011 hmmm it just runs and times out... There must be another issue Link to comment https://forums.phpfreaks.com/topic/243838-brain-fart-with-for-loops/#findComment-1251991 Share on other sites More sharing options...
cunoodle2 Posted August 4, 2011 Share Posted August 4, 2011 AyKay47 had the correct answer. What output, if any are you getting? Can you put it on it's OWN page as I am betting that you have other script on the page that is causing issues.

PFMaBiSmAd Posted August 4, 2011 Share Posted August 4, 2011 There's nothing wrong with your posted code. Your actual code must be modifying the $bathrooms variable inside of the loop.

AyKay47 Posted August 4, 2011 Share Posted August 4, 2011 really what I wrote is just a neater way of writing what the OP had, the way that you wrote it will not cause a timeout...that is normally caused by an infinite loop or something along the sorts...are any errors reported here? edit: also, the newline character that you have in your code "\n" is irrelevant if this is to be parsed as HTML, use a break "<br />" instead Link to comment https://forums.phpfreaks.com/topic/243838-brain-fart-with-for-loops/#findComment-1251996 Share on other sites More sharing options...
guyfromfl Posted August 4, 2011 Author Share Posted August 4, 2011 I commented out the loop and its still running forever... There has to be an issue in the script or with the server...gonna restart and comment out all the php until I find the problem. Thanks.

Pikachu2000 Posted August 4, 2011 Share Posted August 4, 2011 edit: also, the newline character that you have in your code "\n" is irrelevant if this is to be parsed as HTML, use a break "<br />" instead The \n is not irrelevant. It causes a newline in the underlying markup itself.

phpSensei Posted August 5, 2011 Share Posted August 5, 2011 I don't think the code is problem, maybe its because you have too many bathrooms in your house...

Pikachu2000 Posted August 5, 2011 Share Posted August 5, 2011 Then why suggest using a <br> instead? Using \n is the correct way to do what the OP did.

AyKay47 Posted August 5, 2011 Share Posted August 5, 2011 if the OP is looking to create a new line and is viewing this as HTML in the browser, which i presume he is, chances are the newline character "\n" will not give him a line break... which is why i suggested using the html break tag..

Pikachu2000 Posted August 5, 2011 Share Posted August 5, 2011 You might want to read the code in the OP again. The \n is being properly used after the <option></option> tags in a <select> field.
