Php return html and php

Есть ли способ вернуть HTML в PHP-функцию? (без построения возвращаемого значения в виде строки)

У меня есть функция PHP, которую я использую для вывода стандартного блока HTML. В настоящее время он выглядит так:

php function TestBlockHTML ($replStr) < ?>   ?> 

Я хочу вернуть (а не эхо) HTML внутри функции. Есть ли способ сделать это, не создавая HTML (выше) в строке?

Вы можете использовать heredoc , который поддерживает переменную интерполяцию, делая ее довольно аккуратной:

function TestBlockHTML ($replStr) < return HTML; > 

Обратите особое внимание на предупреждение в руководстве, хотя – закрывающая строка не должна содержать пробелов, поэтому нельзя отступать.

Да, есть: вы можете захватить echo текст, используя ob_start :

Это может быть отрывочное решение, и я был бы признателен, если кто-нибудь укажет, является ли это плохая идея, поскольку это не стандартное использование функций. Мне удалось получить HTML из PHP-функции без создания возвращаемого значения в виде строки со следующим:

function noStrings() < echo ''?>
[Whatever HTML you want]
 

Используя этот метод, вы также можете определить переменные PHP внутри функции и вывести их из HTML.

Создайте файл шаблона и используйте механизм шаблона для чтения / обновления файла. Это повысит надежность вашего кода в будущем, а также отдельный дисплей из логики.

Пример использования Smarty :

Файл шаблона

function TestBlockHTML()< $smarty = new Smarty(); $smarty->assign('title', 'My Title'); $smarty->assign('string', $replStr); return $smarty->render('template.tpl'); > 

Другой способ сделать это – использовать file_get_contents () и создать HTML-страницу шаблона

function YOURFUNCTIONNAME($url)

return html from a php function

Hi thank you for your help, I had to amend your code slightly by taking out the $ sign when calling the key inside the foreach. I also added an if statement for best practice reasons.

function machineJobs($jobs)  $output = ""; foreach ($jobs as $job)  if ( isset($job['id']) and isset($job['jobTitle']) and isset($job['jobStartDate']) and isset($job['jobDuration']) and isset($job['qty'])) $output . p">tr>"; $output . p">td>".$job['id']."td>"; $output . p">td>".$job['jobTitle']."td>"; $output . p">td>".$job['jobStartDate']."td>"; $output . p">td>".$job['jobDuration']."td>"; $output . p">td>".$job['qty']."td> tr>"; >> return $output; >

Best way to return html from php function?

I wouldn’t return any HTML. Simply return the error message from the function and then build the html in a more appropriate place. For example the inside the template.

If you may at some point have number of errors, then do like this

This is in case you are not using object oriented way. And assuming that all errors are not fatal and caught in try <> catch () <> blocks.

Generally, I try my best not to echo out HTML via PHP. Why? Because if a designer needs to work on my code, I don’t want him/her worrying about what HTML my functions are spitting out.

Similar Question and Answer

Move the html code into a separate file, error.php. After that you just capture the output:

function errMsg() < ob_start(); include '/path/to/error.php'; return ob_get_clean(); >// . echo errMsg();

First off, I agree with the posts above. Don’t format, just have the function return the bare error message and if you need to format it appropriately where you want to display it.

Secondly, I always find that it is useful to be able to turn error and testing messages on and off quickly. As the majority of my code is object orientated and I might only want to have messages popping from an object at a time, I normally have something like this in my classes:

class userObject < public $history;// = historyObject; public $userName; public $userRelation; public $userCode; private $mySQLAccessData; private $isDebug=false; public function makeHistoryObject($KPI, $KPIType) < if($this->isDebug)userName.".
";> $this->history = new historyObject($this->userCode, $KPI, $KPIType); > > 

I slip a private element in which I leave as false by default. If I need to debug or make changes, I set it to true and all my error/logging messages are neatly displayed on screen. I know that this isn’t directly answering your question, but I do find that it is so handy it might be worth it for you when you start. It certainly beats commenting out and then uncommenting potentially dozens of messages. You can leave these outputs in the object without worrying and have them displaying all the detail you need.

1. Yes definitely, you have no flexibility with the way you are doing it.
2. You should separate all of your HTML from your PHP ideally, at least functions — the only place it is remotely acceptable is within a view which uses PHP just to display the output of the functions.
3. Pizza! Just kidding, but there can never be enough pizza!?

Take a look at the Zend framework http://framework.zend.com/manual/en/zend.application.quick-start.html they forward error messages which aren’t caught to an error handler, which then uses its own view to render the error.

1: You don’t need to, but you can if it’s done properly.

2: To do this, i recommend you to use the EOF in your PHP error func, it looks like this :

function errMsg() < $error = 
O crap! There was an error
  EOF; >
