PHP - regex to allow numbers and symbols only

Hi i am tying to get clean date but there is some thing wrong.
Here is my code.
$in = 'Kb 06/11/2001';
$result = preg_replace("/[^0-9]+/", "", $in);
echo $result;
Output is
06112001
i need output 06/11/2001
Match the slash as well to get the clean date /[^0-9\/]+/
$result = preg_replace("/[^0-9\/]+/", "", $in);
You could also make use of simple array functions in PHP. [A regex alternative]
<?php
$in = 'Kb 06/11/2001';
echo $arr= array_pop(explode(' ',$in)); //"prints" 06/11/2001
Demo
The code explodes your text by space and then pops your last element which is your date.

How to create an hyperlink in a paragraph using php

I would like to create hyperlinks to the words in a paragraph.
For instance if the "Jim Carrey" name is in the array matches the word in string, then the Jim Carrey name should be in Hyperlink of "www.domian.net/name(Jim Carrey)" .
If the "mask" word in the array matches the word in string then it should be replace with corresponding url like "www.domian.net/mask"
<?php
$string="Jim Carrey found the new Mask";
$array=array("Jim Carrey","mask");
echo preg_replace( '/\b('.implode( '|', $array ).')\b/i', '$1', $string );
?>
You seem to have the right idea about how to put a link around the chosen text, but you seem to have not even tried to put in an href. Which is a shame, since it's as simple as typing in the URL with whatever parameter you want.
However, it does get a little complicated because you don't want the same thing both times (you want the literal word in one, but you want name(WORD) in the other). You could try this:
$array = array("Jim Carrey"=>"name(Jim Carrey)","mask"=>"mask");
echo preg_replace_callback("/\b".implode("|",array_keys($array))."\b/i",
function($m) use ($array) {
return "".$m."";
},$string);
<?php
$string="Jim Carrey found the new Mask";
$arr=array("Jim Carrey","Mask");
foreach($arr as $val)
$string = str_replace($val, '' . $val . '', $string);
echo $string;
?>

Function to shorten a specific string

I have this string:
$str="http://ecx.images-amazon.com/images/I/418lsVTc0aL._SL110_.jpg";
Is there a built-in php function that can shorten it by removing the ._SL110_.jpg part, so that the result will be:
http://ecx.images-amazon.com/images/I/418lsVTc0aL
no, there's not any built in URL shortener php function, if you want to do something similar you can use the substring or create a function that generates a short link and stores the long and short value somewhere in database and display only the short one.
well, it depends if you need a regexp replace (if you don't know the complete value) or if you can do a simple str_replace like below:
$str = str_replace(".SL110.jpg", "", "http://ecx.images-amazon.com/images/I/418lsVTc0aL._SL110_.jpg");
You can use preg_replace().
For example preg_replace("/\.[^\.]+\.jpg$/i", "", $str);
I would recommend using:
$tmp = explode("._", $str);
and then using $tmp[0] for your purpose, if you make sure the part you want to get rid of is always separated by "._" (dot-underscore) symbols.
You can try
$str = "http://ecx.images-amazon.com/images/I/418lsVTc0aL._SL110_.jpg";
echo "<pre>";
A.
echo strrev(explode(".", strrev($str), 3)[2]) , PHP_EOL;
B.
echo pathinfo($str,PATHINFO_DIRNAME) . PATH_SEPARATOR . strstr(pathinfo($str,PATHINFO_FILENAME),".",true), PHP_EOL;
C.
echo preg_replace(sprintf("/.[^.]+\.%s$/i", pathinfo($str, PATHINFO_EXTENSION)), null, $str), PHP_EOL;
Output
http://ecx.images-amazon.com/images/I/418lsVTc0aL
See Demo
you could do this substr($data,0,strpos($data,"._")), if what you want is to strip everything after "._"
No, it is not (at least not directly). Such URL shorteners usually generate unique ID and remember your original URL and generated ID. When you enter such url, you start a script, which looks for given ID and then redirect to target URL.
If you want just cut of some portion of your string, then assuming that filename format is as you shown, just look for 1st dot and substr() to that place. Or
$tmp = explode('.', $filename);
$shortName = $tmp[0];
If suffix ._SL110_.jpg is always there, then simply str_replace('._SL110_.jpg', '', $filename) could work.
EDIT
Above was example for filename only. Whole code would be:
$url = "http://ecx.images-amazon.com/images/I/418lsVTc0aL._SL110_.jpg";
$urlTmp = explode('/', $url);
$fileNameTmp = explode( '.', $urlTmp[ count($urlTmp)-1 ] );
$urlTmp[ count($urlTmp)-1 ] = $fileNameTmp[0];
$newUrl = implode('/', $urlTmp );
printf("Old: %s\nNew: %s\n", $url, $newUrl);
gives:
Old: http://ecx.images-amazon.com/images/I/418lsVTc0aL._SL110_.jpg
New: http://ecx.images-amazon.com/images/I/418lsVTc0aL

php preg_replace words last part

$str='<p>http://domain.com/1.html?u=1234576</p><p>http://domain.com/2.html?u=2345678</p><p>http://domain.com/3.html?u=3456789</p><p>http://domain.com/4.html?u=56789</p>';
$str = preg_replace('/.html\?(.*?)/','.html',$str);
echo $str;
I need get
<p>http://domain.com/1.html</p>
<p>http://domain.com/2.html</p>
<p>http://domain.com/3.html</p>
<p>http://domain.com/4.html</p>
remove ?u=*number* from every words last part. thanks.
Change this line:
$str = preg_replace('/.html\?(.*?)/','.html',$str);
into this:
$str = preg_replace('/.html\?(.*?)</','.html<',$str);
An alternative to the other answers:
preg_replace("/<p>([^?]*)\?[^<]*<\/p>/", "<p>$1</p>", $input);
This will match all types of urls with url variables, not only the ones with html-files in them.
For example, you can also extract these types of values:
<p>http://domain.com/1.php?u=1234576</p>
<p>http://domain.com?u=1234576</p>
<p>http://domain.com</p>
<p>http://domain.com/pages/users?uid=123</p>
With an output of:
<p>http://domain.com/1.php</p>
<p>http://domain.com</p>
<p>http://domain.com</p>
<p>http://domain.com/pages/users</p>
This code will load the url's into an array so they can be handled on the fly:
$str = '<p>http://domain.com/1.html?u=1234576</p><p>http://domain.com/2.html?u=2345678</p><p>http://domain.com/3.html?u=3456789</p><p>http://domain.com/4.html?u=56789</p>';
$str = str_replace("<p>","",$str);
$links = preg_split('`\?.*?</p>`', $str,-1,PREG_SPLIT_NO_EMPTY);
foreach($links as $v) {
echo "<p>".$v."</p>";
}

Remove text inside of text from a larger string with PHP

What I'm trying to do is, if it exists, remove an occurrence of text inside a 'shortcode', eg: Here's some content [shortcode]I want this text removed[/shortcode] Some more content to be changed to Here's some content [shortcode][/shortcode] Some more content.
It seems like a pretty simple thing to do but I can't figure it out.. =/
The shortcode will only show up once in the entire string.
Thanks in advance for help.
Try this:
$var = "Here's some content [shortcode]I want this text removed[/shortcode] Some more content";
$startTag = "[shortcode]";
$endTag = "[/shortcode]";
$pos1 = strpos($var, $startTag) + strlen($startTag);
$pos2 = strpos($var, $endTag);
$result = substr_replace($var, '', $pos1, $pos2-$pos1);
It's very easy to do with preg_replace(). For your purpose, use /\[shortcode\].*\[\/shortcode\]/ as pattern.
$replace = "[shortcode][/shortcode]";
$filteredText = preg_replace("/\[shortcode\].*\[\/shortcode\]/", $replace, $yourContent);
See http://php.net/manual/en/function.preg-replace.php for more details.
One can use strpos() to find the position of [substring] and [/substring] in your string and replace the text with a whitespace via substr_replace()
if you do not want to bother with regular expessions:
if you do have the [shortcode] tag inside the string, than it is really no problem: just use a nested use of substr:
substr($string,0,strpos($string,'[substring]')+11)+substr($string,strpos($string,'[/substring]'),strlen($string))
where the first substr cuts the string to the start of the string to cut and the second adds the remaining stuff of the string.
see here:
http://www.php.net/manual/en/function.substr.php
http://www.php.net/manual/en/function.strpos.php
use regex in php to get rid of it.
preg_replace (shortcode, urText, '', 1)
$string = "[shortcode]I want this text removed[/shortcode]";
$regex = "#\[shortcode\].*\[\/shortcode\]#i";
$replace = "[shortcode][/shortcode]";
$newString = preg_replace ($regex, $replace, $string, -1 );
$content = "Here's some content [shortcode]I want this text removed[/shortcode] Some more content to be changed to Here's some content [shortcode][/shortcode] Some more content";
print preg_replace('#(\[shortcode\])(.*?)(\[/shortcode\])#', "$1$3", $content);
Yields:
Here's some content [shortcode][/shortcode] Some more content to be changed to Here's some content [shortcode][/shortcode] Some more content
