php str_replace template with placeholders - php

Question

I have one array for data
$data = array(title=>'some title', date=>1350498600, story=>'Some story');
I have a template
$template = "#title#, <br>#date(d)#<br> #date(m)#<br>#date(Y)#<br> #story#";
All i want is to fit data into template and i know that can be done by str_replace but my problem is the date format. date format is coming from the template not from the data, in data date is stored as php date.
yesterday i tried to ask the same question but i think my question wasn't clear.
Anybody please help me.

Answer 1

i think it won't work with str_replace easily so i'm going to use preg_replace
$data = array('title'=>'some title', 'date'=>1350498600, 'story'=>'Some story');
$template = "#title#, <br>#date(d)#<br> #date(m)#<br>#date(Y)#<br> #story#";
$result = preg_replace_callback('/#(\w+)(?:\\((.*?)\\))?#/', function ($match) use($data) {
$value = isset($data[$match[1]]) ? $data[$match[1]] : null;
if (!$value) {
// undefined variable in template throw exception or something ...
}
if (! empty($match[2]) && $match[1] == "date") {
$value = date($match[2], $value);
}
return $value;
}, $template);
Instead of using date(m) or date(Y) you could also do things like
date(d-m-Y) using this snippet
This has the disadvantage that you can format only the date variable using this mechanism. But with a few tweaks you can extend this functionality.
Note: If you use a PHP version below 5.3 you can't use closures but you can do the following:
function replace_callback_variables($match) {
global $data; // this is ugly
// same code as above:
$value = isset($data[$match[1]]) ? $data[$match[1]] : null;
if (!$value) {
// undefined variable in template throw exception or something ...
}
if (! empty($match[2]) && $match[1] == "date") {
$value = date($match[2], $value);
}
return $value;
}
$data = array('title'=>'some title', 'date'=>1350498600, 'story'=>'Some story');
$template = "#title#, <br>#date(d)#<br> #date(m)#<br>#date(Y)#<br> #story#";
// pass the function name as string to preg_replace_callback
$result = preg_replace_callback('/#(\w+)(?:\\((.*?)\\))?#/', 'replace_callback_variables', $template);

I'd suggest using a templating engine like so:
https://github.com/cybershade/CSCMS/blob/master/core/classes/class.template.php
And then your templates turn out like this:
https://github.com/cybershade/CSCMS/blob/master/themes/cybershade/site_header.tpl
and
https://github.com/cybershade/CSCMS/blob/master/modules/forum/views/viewIndex/default.tpl

Download this file: http://www.imleeds.com/template.class.txt
Rename the extension to .PHP from .TXT
This is something I created years ago, I keep my HTML away from my PHP, always. So see an example below.
<?php
include("template.class.php");
//Initialise the template class.
$tmpl = new template;
$name = "Richard";
$person = array("Name" => "Richard", "Domain" => "imleeds.com");
/*
On index.html, you can now use: %var.name|Default if not found% and also, extend further, %var.person.Name|Default%
*/
//Output the HTML.
echo $tmpl->run(file_get_contents("html/index.html"));
?>
