Examples
Here is a simple example PHP script using the tokenizer that will read in a PHP file, strip all comments from the source and print the pure code only.
Example #1 Strip comments with the tokenizer
<?php
$source = file_get_contents('example.php');
$tokens = token_get_all($source);
foreach ($tokens as $token) {
if (is_string($token)) {
// simple 1-character token
echo $token;
} else {
// token array
list($id, $text) = $token;
switch ($id) {
case T_COMMENT:
case T_DOC_COMMENT:
// no action on comments
break;
default:
// anything else -> output "as is"
echo $text;
break;
}
}
}
?>
Here you can write a comment
There are no comments available yet.
