PHP: php and .html file separation

StackOverflow https://stackoverflow.com/questions/19844082

Question

I'm currently working on separating HTML & PHP code here's my code which is currently working for me.

code.php

<?php
$data['#text#'] = 'A';

$html = file_get_contents('test.html');

echo $html = str_replace(array_keys($data),array_values($data),$html);
?>

test.html

<html>
<head>
<title>TEST HTML</title>
</head>
<body>
<h1>#text#</h1>
</body>
</html>

OUTPUT: A

it search and change the #text# value to array_value A it works for me.

Now i'm working on a code to search "id" tags on html file. If it's searches the "id" in ".html" file it will put the array_values in the middle of >

EX: <div id="test"> **aray_values here** </div>

test.php

<?php

$data['id="test"'] = 'A';

$html = file_get_contents('test.html');

foreach ($data as $search => $value)
{
    if (strpos($html , $search))
    {
        echo 'FOUND';
        echo $value;
    }
}

?>

test.html

<html>
<head>
<title>TEST</title>
</head>
<body>
<div id="test" ></div>
</body>
</html>

My problem is I don't know how to put the array_values in the middle of every ></ search in the .html file.

Desired OUTPUT: <div id="test" >A</div>

Was it helpful?

Solution 

function callbackInsert($matches)
{
    global $data;
    return $matches[1].$matches[3].$matches[4].$data[$matches[3]].$matches[6];
}


$data['test'] = 'A';

$html = file_get_contents('test.html');

foreach ($data as $search => $value)
{
    preg_replace_callback('#(<([a-zA-Z]+)[^>]*id=")(.*?)("[^>]*>)([^<]*?)(</\\2>)#ism', 'callbackInsert', $html);
}

Warning: code is not tested and could be improved - re global keyword and what items are allowed between > and

Regular expression explanation:

(<([a-zA-Z]+) - any html tag starting including the last letter of the tag
[^>]* - anything that is inside a tag <>
id=")(.*?)(" - the id attribute and its value
[^>]* - anything that is inside a tag <>
>) - the closing tag
([^<]*?) - anything that is not a tag, tested by opening a tag <
(</\\2>) - the closing tag matching the 2nd bracket, ie. the matching opening tag

OTHER TIPS

Use views (.phtml) files to dynamically generate content. This is native for PHP (no 3rd party required).

See this answer: What is phtml, and when should I use a .phtml extension rather than .php?
