How to read a csv file with php code inside? - php

Question

i searched Google but found nothing what fits for my problem, or i search with the wrong words.
In many threads i read, the smarty Template was the solution, but i dont wont use smarty because its to big for this little project.
My problem:
I got a CSV file, this file contents only HTML and PHP code, its a simple html template document the phpcode i use for generating dynamic imagelinks for example.
I want to read in this file (that works) but how can i handle the phpcode inside this file, because the phpcode shown up as they are. All variables i use in the CSV file still works and right.
Short Version
how to handle, print or echo phpcode in a CSV file.
thanks a lot,
and sorry for my Bad english

Formatting your comment above you have the following code:
$userdatei = fopen("selltemplate/template.txt","r");
while(!feof($userdatei)) {
$zeile = fgets($userdatei);
echo $zeile;
}
fclose($userdatei);
// so i read in the csv file and the content of csv file one line:
// src="<?php echo $bild1; ?>" ></a>
This is assuming $bild1 is defined somewhere else, but try using these functions in your while loop to parse and output your html/php:
$userdatei = fopen("selltemplate/template.txt","r");
while(!feof($userdatei)) {
$zeile = fgets($userdatei);
outputResults($zeile);
}
fclose($userdatei);
//-- $delims contains the delimiters for your $string. For example, you could use <?php and ?> instead of <?php and ?>
function parseString($string, $delims) {
$result = array();
//-- init delimiter vars
if (empty($delims)) {
$delims = array('<?php', '?>');
}
$start = $delims[0];
$end = $delims[1];
//-- where our delimiters start/end
$php_start = strpos($string, $start);
$php_end = strpos($string, $end) + strlen($end);
//-- where our php CODE starts/ends
$php_code_start = $php_start + strlen($start);
$php_code_end = strpos($string, $end);
//-- the non-php content before/after the php delimiters
$pre = substr($string, 0, $php_start);
$post = substr($string, $php_end);
$code_end = $php_code_end - $php_code_start;
$code = substr($string, $php_code_start, $code_end);
$result['pre'] = $pre;
$result['post'] = $post;
$result['code'] = $code;
return $result;
}
function outputResults($string) {
$result = parseString($string);
print $result['pre'];
eval($result['code']);
print $result['post'];
}

Having PHP code inside a CSV file that should be parsed and probably executed using eval sounds pretty dangerous to me.
If I get you right you just want to have dynamic parameters in your CSV file right? If thats the case and you don't want to implement an entire templating language ( like Mustache, Twig or Smarty ) into your application you could do a simple search and replace thing.
$string = "<img alt='{{myImageAlt}}' src='{{myImage}}' />";
$parameters = [
'myImageAlt' => 'company logo',
'myImage' => 'assets/images/logo.png'
];
foreach( $parameters as $key => $value )
{
$string = str_replace( '{{'.$key.'}}', $value, $string );
}
