I am writing a project with template adding feature. And want to have simple variables in template thats why I want to define some variables or some thing like that instead of using :
<?php echo $variable; ?>
I want to have some thing like :
{$varaible}
how can I do that ? actually how can I create my simple template engine ? thanks.
You can do it using any existing template engines or by the following code set.
Create a template file as shown below ( Tweak the HTML , add more template variables or anything ). Save this to a file and call it mytemplate.txt
<html>
<head>
<title>{title}</title>
</head>
<body>
<h1>{header}</h1>
{text}
</body>
</html>
Create a PHP file , and call it home.php ( Or any name depending on your use case ) . Add the following code.
<?php
$tags['title']="Replaces title tag";
$tags['header']="Replaces header tag";
$tags['text']="Replaces text tag";
//lets us open your template file and replace the tags
print preg_replace("/\{([^\{]{1,100}?)\}/e","$tags[$1]",file_get_contents("mytemplate.txt"));
?>
Make sure that mytemplate.txt, and home.php are in the same directory on your server.
Note :- This gives you a basic template engine, using preg_replace function of PHP.
Here are the references
First of all, you will have to define your variables
Next you will have to use this PHP function to do your replacements str_replace
http://php.net/str_replace
// Provides: You should eat pizza, beer, and ice cream every day
$phrase = "You should eat fruits, vegetables, and fiber every day.";
$healthy = array("fruits", "vegetables", "fiber");
$yummy = array("pizza", "beer", "ice cream");
$newphrase = str_replace($healthy, $yummy, $phrase);
Apply the same to your template and it works just fine.
mixed str_replace ( mixed $search , mixed $replace , mixed $subject [, int &$count ] ) Do you understand that at all? If you do then you will know that it can be used even for your newsletter templates. READ MOREpreg_replace simply use str_replace and it will do what you want. It can simply take more examples to show you exactly what you want done...
