I want to make certain words/strings like links if found in the text. I have a piece of code from php.bet which does that, but it also removes the beginning and end of tags from <img src="my_image.jpg" />. Can you help solve this?
Here's the piece of code:
PHP Code:
<?php
$str_in = '<p>Hi there worm! You have a disease!</p><img src="my_image.jpg" />
';
$replaces= array(
'worm' => 'worm.html',
'disease' => 'disease.html'
);
function addLinks($str_in, $replaces)
{
$str_out = '';
$tok = strtok($str_in, '<>');
$must_replace = (substr($str_in, 0, 1) !== '<');
while ($tok !== false) {
if ($must_replace) {
foreach ($replaces as $tag => $href) {
if (preg_match('/\b' . $tag . '\b/i', $tok)) {
$tok = preg_replace(
'/\b(' . $tag . ')\b/i',
'<a title="' . $tag . '" href="' . $href . '">\1</a>',
$tok,
1);
unset($replaces[$tag]);
}
}
} else {
$tok = "<$tok>";
}
$str_out .= $tok;
$tok = strtok('<>');
$must_replace = !$must_replace;
}
return $str_out;
}
echo addLinks($str_in, $replaces);
The result is:
PHP Code:
Hi there worm! You have a disease!
img src="my_image.jpg" /< >
The "worm" and "disease" words are transformed into links like desired, but the rest...
Thanks a lot!
