What's the proper way to check if a date is empty or not?
imgrooot posted a topic in PHP Coding Help
Say I have a simple date like this. $date = 2017-08-10 00:06:10; I would like to have an if statement that tells me whether or not the date is empty. These are my methods but I'm not sure if it's the proper way of doing it. . if(empty($date)) { // do nothing } else { // do something } if($date == 0000-00-00 00:00:00) { // do nothing } else { // do something } -

Hi, I have a little snipplet I am posting here, I am not very experienced with PHP but thought I would ask some of you for help. I have to modify a program and a very small part of it is to remove lines where values are being set to blank or '' null values. Here is the little code snipplet: echo "\t\tfor(index=0; index < $maxclothrows; index++)\n"; echo "\t\t{\n"; echo "\t\t\tdocument.pickDivision.cloth.options[index].text = '';\n"; echo "\t\t\tdocument.pickDivision.cloth.options[index].value = '';\n"; echo "\t\t}\n\n"; This above code is used to set some values to ' ', but then after I would like those blank values removed rather then showing up in the list because when I scroll down you have a whole bunch of blank lines. How can I remove these completely? Maybe: echo "\t\t\if(document.pickDivision.cloth.options[index].text = '') {...some code here to remove this blank line} I read about regex or some str_replace, but am not sure how to use it. This program is around 3000 lines of code, so don't think I can attach the file. Any help would be greatly appreciated!
