Little change of code posted by nielsvandenberge where is some bugs (text started with
[img]name.jpg[/img] wasn't showed and now funcions aren't recursively - now funcions run
iteratively)
<?php
function replaceMessage($message) {
$message = strip_tags($message,
'<b></b><i></i><u></u><a></a><img>');
$message = str_replace ("\n", "<BR>", "$message");
// When you store the $message in a database you might get errors cause of the quotes
$message = str_replace("[singleQuote]", "'", $message);
$message = str_replace("[doubleQuote]", "\"", $message);
$message = str_replace ("[U]", "<U>", "$message");
$message = str_replace ("[/U]", "</U>", "$message");
$message = str_replace ("[I]", "<I>", "$message");
$message = str_replace ("[/I]", "</I>", "$message");
$message = str_replace ("[B]", "<B>", "$message");
$message = str_replace ("[/B]", "</B>", "$message");
$message = replaceUrl($message);
$message = replaceImg($message);
return $message;
}
function replaceImg($message) {
// Make image from [img]htp://.... [/img]
while(strpos($message, "[img]")!==false){
$begImg = strpos($message, "[img]");
$endImg = strpos($message, "[/img]");
$img = substr($message, $begImg, $endImg-$begImg+6);
$link = substr($img, 5, $endImg - $begImg -5);
$htmlImg = "<img src=$link border='0'>";
$message = str_replace($img, $htmlImg, $message);
// searches for other [img]-nodes
}
return $message;
}
function replaceUrl($message) {
// Make link from [url]htp://.... [/url] or [url=http://.... ]text[/url]
while(strpos($message, "[url")!==false){
$begUrl = strpos($message, "[url");
$endUrl = strpos($message, "[/url]");
$url = substr($message, $begUrl, $endUrl-$begUrl+6);
$posBracket = strpos($url, "]");
if ($posBracket != null){
if ($posBracket == 4){
// [url]http://.... [/url]
$link = substr($url, 5, $endUrl - $begUrl -5);
$htmlUrl = "<a href=$link
target='_blank'>$link</A>";
} else {
// [url=http://....]text[/url]
$link = substr($url, 5, $posBracket-5);
$text = substr($url, $posBracket+1, strpos($url, "[/url]") -
$posBracket-1);
$htmlUrl = "<a href=$link
target='main'>$text</A>";
}
}
$message = str_replace($url, $htmlUrl, $message);
// searches for other [url]-nodes
}
return $message;
}
?>
Some other upgrades are possible :)
