PHP variables and loops in HTML format

StackOverflow https://stackoverflow.com/questions/23262002

Question

page.html

<body>
   <h1>{{HEADING1}}</h1>  {{CONTENT1}}
   <h2>{{NEWSLETTER}}</h2>
   <h1>{{VAR1}}</h1>  {{VAR2}}
</body>

page.php

$HEADING    = 'Heading';
$CONTENT    = '
              <div align="center">
              -- Content goes here --
              </div>
              ';
$NEWSLETTER = 'newsletter content';
$VAR1       = 'Another Sub Heading';
$VAR2       = 'content';

$File       = file('page.html');
print $File;

1> While the url http://example.com/page.php executes, All the {{VARIABLE}} should replace by the value in $VARIABLE.

2> Also I want to call the PHP loop inside HTML
Something Like 

BEGIN WHILE LOOP
CONTENTS
END

What are the best methods (or Regular Expression) to implement these?

Était-ce utile?

La solution

The below can be used to change the variables $HEADING to {{HEADING}} 

   $File          = file('file.html');
   $FContent      = join("", $File);
   $FileContent   = preg_replace("/{{(.*?)}}/e","@$$1", $FContent);

   print $FileContent;

Autres conseils

what about using a template engine? See Twig

you will have to set the variables in your PHP files like this

return array("variable" => "variable_content");

and then use it in the HTML files this way:

Content: {{variable}}

in the HTML you can also loop with Twig syntax

{% for var in variables %}
   Content: {{var}}
{% endfor %}

You can use str_replace here:

$File = str_replace("{{HEADING}}",$HEADING,$File);
$File = str_replace("{{CONTENT}}",$CONTENT,$File);
print $File;
