How to insert template in php file - php

Question

I 've used the following code to create PHP file dynamically
$value = 5;
$file = $compname.'.php';
$file_pointer = fopen( $file, 'w' );
$string = '<?php $var = '. $value .' ?>';
fwrite( $file_pointer, $string );
fclose($file_pointer);
include($file);
echo $var;
Is it possible to insert template in that php file and the file name conatins spaces is it possible to remove those space and add "-"

Answer 1

As #ianhales mentioned, you can use str_replace() for replacing white-spaces in the name. If I understand your question correctly, you want to use a template file to generate the contents of the PHP file. To do that, I would do the following.
Create template.txt file
<?php
$var = #THEVAR#;
?>
Then you use the template:
<?php
...
$value = 5;
$template = file_get_contents('template.txt');
$template = str_replace("#THEVAR#", $value, $template);
$newFile = fopen($compname.'.php', 'w');
fwrite($newFile, $template);
fclose($newFile);
...

Answer 2

str_replace( ) will do your ' ' to '-' replacement. The rest of your question I don't understand.

Do you mean you want to have a pre made PHP file and change some stuff there?
You can use placeholders, for instance.
example
PHP FILE
<?php
$var = '[%%VAR1%%]';
?>
file editor:
//Change filename
str_replace(' ', '-', $compname);
//File "template editor"
$value = 5;
$file = file_get_contents($compname.'.php');
str_replace('[%%VAR1%%]',$value, $file);
file_put_contents($compname.'.php', $file);

You did not mention if you want your template file to be PHP parsed first. This method could do (or not):
function getTemplateContent($includeFile, $parsePhp = TRUE) {
$cont = '';
if ($parsePhp) {
try {
ob_start();
require($includeFile);
$cont = ob_get_contents();
ob_end_clean();
} catch (Exception $ex) {
$cont = '';
}
} else {
$cont = file_get_contents($includeFile); #
}
return $cont;
}
To include the template contents in the written file could be done like e.g.
$string = '<?php $var = '. $value . ';' . getTemplateContent($templateFile, TRUE/FALSE) . ' ?>'
