[[SOLVED] Remove only line breaks between [code] [/code]]

Except I think you can simplify your pattern by eliminating all captures (of course, this assumes that there is no newlines / carriage returns within the code tags themselves  )

 

Yeah, should've thought of that

 

A minor side note regarding escaped characters; some escape sequences can be avoided (of course, this is no big deal though)

 

I know this, but I tend to always escape literal square brackets, to make it less confusing for less experienced regex'ers.

[match once]

FYI, preg_match_all() returns the number of full pattern matches.

[Reg Ex]

If you're searching for a plain string, use strpos() or stripos() for case insensitivity:

 

<?php
if (strpos($var, 'srv_9 (Dead ???)') !== false) {
echo '$var contains the searched string.';
}
?>

[Filtering for a phrase using pregmatch]

Something like

 

<?php
preg_match_all('~\bsrc\s?=\s?([\'"])(http://.+?)\1~is', $value, $matches);
foreach ($matches[2] as $url) {
if (strpos($url, 'pass') !== false) {
	echo "Match found: $url";
	break;
}
}
?>

 

You can use stripos() if the search should be case insensitive.

[Counting HTML Tags: how? -new at REGex.]

I'd go along with what cags has said. If you want to match using the preg_match_all I'd use '%<b(\b[^>]*)?>%i' as your regex

 

Just a small note; you can remove the optional capture since the word boundary will match even if the following character class (quantized with the asterisk) matches zero times.

 

'~<b\b[^>]*>~i'

[[SOLVED] Remove only line breaks between [code] [/code]]

My approach:

 

<?php
$str = 'Text with a
linebreak
[code=test]test
test
test

test2
test2

test2
test2

';

$str = preg_replace_callback(

'~(\

[code[^\]]*\])(.*?)(\[/code\])~is',
create_function(
'$matches',
'return $matches[1] . str_replace(array("\r\n", "\r", "\n"), \'<br />\', $matches[2]) . $matches[3];'
),
$str
);
//run your bbcode function here, including nl2br()
echo $str;
?>[/code]

[[SOLVED] remove [quote]and everything in it [/quote]]

Add is after the last ~ to make the search case insensitive and to make the dot match line breaks. If it also should remove empty quote tags like

, use an asterisk instead of the plus.

 

~\[quote\].*?\[/quote\]~is

[[SOLVED] Splitting a string by text&number. Ex djk44jkasd32sd --> djk/44/jkasd/32/sd how?]

You can use something like

 

<?php
$str = 'djk44jkasd32sd';
$parts = preg_split('~([0-9]+)~', $str, null, PREG_SPLIT_DELIM_CAPTURE);
echo '<pre>' . print_r($parts, true) . '</pre>';
?>

[[SOLVED] Replace text within tags with formatted version]

I would do something like this:

 

<?php
$str = '<a href="test.php">test</a>
<br />
[nohtml]
<a href="test2.php">test2</a>
[/nohtml]';
$str = preg_replace_callback(
'~\[nohtml\](.*?)\[nohtml\]~is',
create_function(
	'$matches',
	'return htmlentities($matches[1], ENT_QUOTES);'
),
$str
);
echo $str;
?>

 

preg_replace_callback() @ the manual.

[[SOLVED] A semi-complicated regex]

Another thing to take into account is if you wish to handle nested quotes, which I'd imagine you quite likely do. Prepare for headaches

 

You can quite easily support nested tags by dealing with the opening and closing tags separately.

[[SOLVED] Loading URL from XML]

Can't see why this shouldn't work:

 

<?php
if (isset($_GET['url'])) {
$converter = array(
	'blankspot' => 'blanks',
	'soccer' => '906',
	'blankspothere' => 'blank'
);
$url = $_GET['url'];

if (isset($converter[$url])) {
	$xml = @simplexml_load_file('/flv_player/data/playerConfigEmbed/' . $converter[$url] . '.xml');
	if ($xml) {
		echo (string) $xml->media->content->video['SD'];
		exit;
	}
}
}
header('Location: http://www.sqweasel.com/');
?>

[[SOLVED] Help Hiding links]

Are you using session_start()?

[[SOLVED] Need help on a specific match, content of a "<pre>" tag ...]

No it doesn't.

 

But for some reason it escapes the quotes. When I use this instead, it doesn't:

 

preg_replace('~(<pre\b[^>]*>)(.*?)(</pre>)~ise', '"$1" . htmlentities("$2") . "$3"', $my_text);

[[SOLVED] Need help on a specific match, content of a "<pre>" tag ...]

Yep, just add the s modifier after the pattern (I also added a word boundary and made the search case insensitive):

 

preg_replace('~<pre\b[^>]*>(.*?)</pre>~ise', 'htmlentities(\'$1\')', $my_text);

If you want to retain the pre tags around the matched content, just grab the tags and use them in the replacement:

 

preg_replace('~(<pre\b[^>]*>)(.*?)(</pre>)~ise', '\'$1\' . htmlentities(\'$2\') . \'$3\'', $my_text);

I'm grabbing the last match to be sure the casing is right. Guess it's not necessary though.

[using the glob function with a $ function]

Absolutely right. But why ask when you can try it out in like 1 sec?

[using the glob function with a $ function]

In your sample code you're using $path before you've set it?

[convert & to &]

str_replace()

[Weird Formatted Apostrophe Problem]

Could also have something to do with the character encoding. If you post a file including a sample string with the odd characters, we can test your code and see our results.

[How can i save the newly created div with texts?]

Could be done with a database and AJAX. Or without AJAX, if you can live with it reloading the page on submit.

[Weird Formatted Apostrophe Problem]

1. Does slashes effect the function I've used above?

2. Does it matter what I'm copying and pasting. ie if I were to copy and paste text which had an apostrophe written as &#39; would that effect how my function handles it?

 

1. No.

2. If your apostrophes are represented with HTML entities, that's where your problem lies. When you output your sample string, check the source code of it, and see if you find any HTML entities. If you do, you can simply replace them with something like

 

$str = str_replace(''', "'", $str);

 

or by using html_entity_decode(), but that will convert all HTML entities to the characters they represent.

[New to regex but can't solve this problem]

Lol, I was about to post this, but then you beat me to it, haha:

 

Then you don't need \K at all, but just

 

$input = preg_replace('~<content[^>]*>~i', '', $input);

And my advance apologies goes to nrg, who is probably in the process of writing an elaborate answer (no offence - you do a great job explaining things in detail, while my answers just often aren't that long).

[Timer]

So have you considered using sleep() within your loop?

[Twitter @ replies and emails]

Those are just the pattern delimiters of my preference. They can be any non-white space, non-alphanumeric ASCII character (except a backslash). And it's always smart to use delimiters that don't appear within the pattern, so you don't have to escape them, hence my use of the 'odd' tildes (I have yet to write a pattern matching a tilde). When you're using forward slashes as pattern delimiters, you would have to escape any forward slashes inside the pattern - something that occurs quite often.

[Twitter @ replies and emails]

Edited your patterns a bit:

 

$text = preg_replace('~\S+@\S+\.[a-z]+~i', '<a href="mailto:$0">$0</a>', $text);
$text = preg_replace('~(^|\s)@([a-z0-9_]+)~i', '$1@<a href="http://twitter.com/$2" target="_blank">$2</a>', $text);

The email one being this simple will also convert invalid emails, but it should at least work properly now.

[isolating msie ver.]

Try something like

 

<?php
if (preg_match('~MSIE ([^;]+);~', $_SERVER['HTTP_USER_AGENT'], $match)) {
echo 'Internet Explorer version: ' . htmlentities($match[1]);
} else {
echo 'Browser isn\'t Internet Explorer';
}
?>

 

I'm using htmlentities() because the user agent string can be spoofed by the user, potentially containing malicious code to be executed.
