Hello Stackers,
I'm just having a small PHP Question about the str_replace() Function. When I replace something, it will just replace everything; That's okay. But what I would like to know is this:
str_replace("*", "<strong>", $message);
Is it possible to use str_replace for codes like * This content is Bold *, just having the content, but still replacing the asterisk's with <strong> and </strong>?
Example:
Original: **This Should be Bold**
After Replacing: <strong>This Should be Bold</strong>
For people flagging this as a Duplicate: It's not about closing HTML Tags, it's about replacing.
I Hope I'm not that unclear. Thanks.
Use regular expression instead; it's more convenient:
$message = "**This Should be Bold**";
$message = preg_replace('#\**([^\*]+)\**#m', '<strong>$1</strong>', $message);
echo $message;
Or if you want to limit the number of asteroids to 2:
'#\*{1,2}([^\*]+)\*{1,2}#m'
You can also do like this

<?php
$string = '**This Should be Bold**';
$string = preg_replace("/\*\*(.+?)\*\*/", "<strong>$1</strong>", $string);
echo $string;
?>

I have a string that looks like this
$t="<b>vist</b>thank you for the follow.";
I am trying to remove the tag b and put an "#" instead of this tag.
I tried this
str_replace("<b></b>","#",$t);
but it doesn't replace the closing tag.
I don't know why it is not working may be there is something omitted in the code.
Try with
$search = array('<b>','</b>');
$replace = '#';
echo str_replace($search, $replace, $t);
To replace multiple words using str_replace() function,
You can Try this
$t="<b>vist</b> thank you for the follow";
$pattern=array();
$pattern[0]="<b>";
$pattern[1]="</b>";
$replacement=array();
$replacement[0]="#";
$replacement[1]="";
echo str_replace($pattern,$replacement,$t);

Try with -
$t="<b>vist</b>";
echo str_replace(array("<b>", "</b>"),"#",$t);
I'm trying to scrape a website using some regex. But the site isn't written in well formatted html. In fact, the html is horrible and not structured hardly at all. But I've managed to tackle most of it. The problem I'm encountering now is that in some emails, a span is wrapped around a random part of the email like so:
****.*******#g<span class="tournamenttext">mail.com</span>
************<span class="tournamenttext">#yahoo.com</span>
<span class="tournamenttext">**********#mail.com</span>
*******#gmail.com
Is there a way to retrieve the emails with all this inconsistency?
$string ='****.*******#g<span class="tournamenttext">mail.com</span>
************<span class="tournamenttext">#yahoo.com</span>
<span class="tournamenttext">**********#mail.com</span>
*******#gmail.com';
$pattern = "/<\/?span[^>]*>/";
$string = preg_replace($pattern, "", $string);
after that $string will be only mails
****.*******#gmail.com
************#yahoo.com
**********#mail.com
*******#gmail.com
Your code will be like this
$text[1]->innertext = "Where innertext contains something like: "<em>Local (Open)
Tournament.</em> ****.*******#g<span class="tournamenttext">mail.com</span>"
// Firstly clear spans
$pattern = "/<\/?span[^>]*>/";
$text[1]->innertext = preg_replace($pattern, "", $text[1]->innertext);
// Preg Match mail
$email_regex = "^[_a-z0-9-]+(\.[_a-z0-9-]+)*#[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$"; // Just an example email match regex
preg_match($email_regex, $text[1]->innertext, $theMatch);
echo '<pre>' . print_r($theMatch, true) . '</pre>';
You could simply remove all span tags by replacing </?span[^>]*> with nothing and try your favourite email address finder on the result.
How can i remove the link and remain with the text?
text text text. <br><a href='http://www.example.com' target='_blank' title='title' style='text-decoration:none;'>name</a>
like this:
text text text. <br>
i still have a problem.....
$text = file_get_contents('http://www.example.com/file.php?id=name');
echo preg_replace('#<a.*?>.*?</a>#i', '', $text)
in that url was that text(with the link) ...
this code doesn't work...
what's wrong?
Can someone help me?
I suggest you to keep the text in link.
strip_tags($text, '<br>');
or the hard way:
preg_replace('#<a.*?>(.*?)</a>#i', '\1', $text)
If you don't need to keep text in the link
preg_replace('#<a.*?>.*?</a>#i', '', $text)
While strip_tags() is capable of basic string sanitization, it's not fool-proof. If the data you need to filter is coming in from a user, and especially if it will be displayed back to other users, you might want to look into a more comprehensive HTML sanitizer, like HTML Purifier. These types of libraries can save you from a lot of headache up the road.
strip_tags() and various regex methods can't and won't stop a user who really wants to inject something.
Try:
preg_replace('/<a.*?<\/a>/','',"test test testa<br> <a href='http://www.example.com' target='_blank' title='title' style='text-decoration:none;'>name</a>");
this is my solutions :
function removeLink($str){
$regex = '/<a (.*)<\/a>/isU';
preg_match_all($regex,$str,$result);
foreach($result[0] as $rs)
{
$regex = '/<a (.*)>(.*)<\/a>/isU';
$text = preg_replace($regex,'$2',$rs);
$str = str_replace($rs,$text,$str);
}
return $str;}
A version from the above compiled notes:
$withoutlink = preg_replace('/<a.*>(.*)<\/a>/isU','$1',$String);
strip_tags() will strip HTML tags.
Try this one. Very simple!
$content = "text text text. <br><a href='http://www.example.com' target='_blank' title='title' style='text-decoration:none;'>name</a>";
echo preg_replace("/<a[^>]+\>[a-z]+/i", "", $content);
Output:
text text text. <br>
Try:
$string = preg_replace( '#<(a)[^>]*?>.*?</\\1>#si', '', $string );
Note:
this code remove link with text.
One more short solution without regexps:
function remove_links($s){
while(TRUE){
#list($pre,$mid) = explode('<a',$s,2);
#list($mid,$post) = explode('</a>',$mid,2);
$s = $pre.$post;
if (is_null($post))return $s;
}
}
?>
I have a variable $link_item, it's used with echo and gives the strings like
<span class="name">Google</span>http://google.com
How to remove "<span class="name">Google</span>" from string?
It should give just "http://google.com".
Heard it can be done with regex(), please help.
Without regex:
echo substr($link_item, stripos($link_item, 'http:'))
But this only works if the first part (i.e. <span class="name">Google</span>) never contains http:. If you can assure this: here you go :)
Reference: substr, stripos
Update:
As #Gordon points out in his comment, my code is doing the same as strstr() already does. I just put it here in case one does not read the comments:
echo strstr($link_item, 'http://');
$string = '<span class="name">Google</span>http://google.com';
$pieces = explode("</span>",$string);
//In case there is more than one span before the URL
echo $pieces[count($pieces) -1];
Solved:
$contents = '<span class="name">Google</span>http://google.com';
$new_text = preg_replace('/<span[^>]*>([\s\S]*?)<\/span[^>]*>/', '', $contents);
echo $new_text;
// outputs -> http://google.com
Don't use a regex. Use a HTML parser to extract only the text you want from it.
Made myself
$link_item_url = preg_replace('#<span[^>]*?>.*?</span>#si', '', $link_item);
This will remove any <span + something + </span> from variable $link_item.
Thanks for all.
Using PHP, given a string such as: this is a <strong>string</strong>; I need a function to strip out ALL html tags so that the output is: this is a string. Any ideas? Thanks in advance.
PHP has a built-in function that does exactly what you want: strip_tags
$text = '<b>Hello</b> World';
print strip_tags($text); // outputs Hello World
If you expect broken HTML, you are going to need to load it into a DOM parser and then extract the text.
What about using strip_tags, which should do just the job ?
For instance (quoting the doc) :
<?php
$text = '<p>Test paragraph.</p><!-- Comment --> Other text';
echo strip_tags($text);
echo "\n";
will give you :
Test paragraph. Other text
Edit : but note that strip_tags doesn't validate what you give it. Which means that this code :
$text = "this is <10 a test";
var_dump(strip_tags($text));
Will get you :
string 'this is ' (length=8)
(Everything after the thing that looks like a starting tag gets removed).
strip_tags is the function you're after. You'd use it something like this
$text = '<strong>Strong</strong>';
$text = strip_tags($text);
// Now $text = 'Strong'
I find this to be a little more effective than strip_tags() alone, since strip_tags() will not zap javascript or css:
$search = array(
"'<head[^>]*?>.*?</head>'si",
"'<script[^>]*?>.*?</script>'si",
"'<style[^>]*?>.*?</style>'si",
);
$replace = array("","","");
$text = strip_tags(preg_replace($search, $replace, $html));
