问题 Is it possible to format a number to 2 decimal places with Smarty PHP? Thanks. 回答1: string_format accepts sprintf formatting options: {$number|string_format:"%.2f"} 回答2: {$number|number_format:2} is what you want 回答3: {$number|round:"2"} also works 回答4: To display 2 instead of 2.00 you can use : replace in Smarty PHP See below example - $number = 2.00 {$number|replace:'.00':''} Output :- 2 Hope this helps. 来源： https://stackoverflow.com/questions/2409110/is-it-possible-to-format-a-number-to-2

问题 So I have an assigned variable in smarty: {assign var=number value=0} Now I can increment it using {$number++} or {++$number} Which is exactly what I need, only problem is, it displays the value of $number on the page.

问题 In Smarty, is there a standard function or an easy way to generate json from an array, as json_encode() does in php? Actually It seems there is not in smarty documentation but wanted to ask anyways. Thanks, Sinan. 回答1: This should work. The @ makes smarty run the modifier against the whole array, otherwise it does it for each element. {$myarray|@json_encode} If $escape_html is enabled, you will need to use nofilter : {$myarray|@json_encode nofilter} 回答2: While {$myarray|@json_encode} does in
