There is certainly nothing wrong with single quotes in this case, since there is no need for variable interpolation within the quoted string literal. However, unless you are using a very old version of PHP where there was some measurable performance gain for using single quotes when no such interpolation was needed, it's purely a style/taste preference. I tend to use double quotes by default so that I can include interpolated varaibles and/or use any of the specialescape sequences if/when I need them.
Quick Noob Syntax Questions
Hi I’m very new to PHP and I’m have a small problem.
I have my grandtotal variable displaying using the code below
[code]echo “<tr><td>Grand Total:”.$grandtotal.”</td></tr>”;
but I need it to round up to have only 2 decimal places it seems to work when i try this
[code]echo (number_format(“$grandtotal”, 2));
but I need it to be placed inside my table and I’m unsure of the syntax i’ve tried something like this with no luck.
[code]echo “<tr><td>Grand Total:”(number_format($grandtotal,2))”</td></tr>”;
can someone help me out with the syntax on this one?
thanks
