I want to replace the <a href='http://example.org/'>this word</a> element. But the problem is that "this word" can be any word.
<?php
$link = "http://example.com";
$site = file_get_contents($link);
$ades = "<a href='http://example.org/'>this word</a>";
$bdes = "";
$site = str_replace($ades,$bdes,$site);
echo $site;
?>
'This word' is a variable
'This word' can be pink, blue, door etc.
How can I get it?

I just want to remove like these codes
blaasdsad

ertvvuyrt
awceawce
8k9789k789k
and else
$ades = "<a href='http://example.org/'>this word</a>";
echo strip_tags($ades);
Just use strip_tags function to remove the html tags. The output will be a string with the color name.
More info about strip_tags Here!!!
If your question is how to access every tag of your actual page which has this form <a href='http://example.org/'>any text or word</a>, I would use preg_replace, which use a pattern to detect what to change (instead of a string).
For your string, it would render something like that:
<?php
$link = "http://example.com";
$site = file_get_contents($link);
// use a pattern
$ades = "/^<a href='http:\/\/example\.org\/'>.*<\/a>$/";
$bdes = "";
// use other function
$site = preg_replace($ades,$bdes,$site);
echo $site;
?>
Try this:
$var="blue";
$ades = "<a href='http://example.org/'>".$var."</a>";
$shortAdes=substr($ades,strpos($ades,$var),strlen($var));
echo $shortAdes;
it weill print the $var

I have a code for embedding a link for iframe.
$post_contetn = explode('htt',$content);
$content_with_link = $post_contetn[0];
$link = 'htt'.$post_contetn[1];
But the problem is that, if I write
http://www.espn.com was great
then it links "was great" is part of the $link.
How can I change (perhaps use regex) to only include the actual url?
======
If I incorporate siam's answer, should it be
$regex = '/https?:\/\/.*?(?=\s)/';
$post_contetn = preg_match($regex, $content, $linkarray);
$content_with_link = $post_contetn[0];
$link = $linkarray[0]
echo $content_with_link;
I then edited to
preg_match($regex, $content, $post_contetn);
$content_with_link = $post_contetn[0];
$link = $post_contetn[0]
echo $content_with_link;
But the error still occurs at echo line.
Try using the following regex :
(?:https?:\/\/\S+)?\S+\.\S+\.?\S+
see demo / explanation
PHP
<?php
$content = 'http://www.espn.com was great';
$regex = '/(?:https?:\/\/\S+)?\S+\.\S+\.?\S+/';
preg_match($regex, $content, $post_contetn);
$link = $post_contetn[0];
echo $link;
?>
I am working on a script with templates. So I have this PHP code:
<?php
$string = "TEST";
echo(file_get_contents('themes/default/test.html'));
?>
And I have this HTML (the test.html file):
<html>
<p>{$string}</p>
</html>
How can I make PHP actually display the variable inside the curly brackets? At the moment it displays {$string}.
P.S:
The string might also be an object with many many variables, and I will display them like that: {$object->variable}.
P.S 2: The HTML must stay as it is. This works:
$string = "I'm working!"
echo("The string is {$string}");
I need to use the same principle to display the value.
You can use the following code to achieve the desired result:
<?php
$string = "TEST";
$doc = file_get_contents('themes/default/test.html'));
echo preg_replace('/\{([A-Z]+)\}/', "$$1", $doc);
?>
P.S. Please note that it will assume that every string wrapped in { }
has a variable defined. So No error checking is implemented in the code above. furthermore it assumes that all variables have only alpha characters.
If it is possible to save your replacees in an array instead of normal variables you could use code below. I'm using it with a similar use case.
function loadFile($path) {
$vars = array();
$vars['string'] = "value";
$patterns = array_map("maskPattern", array_keys($vars));
$result = str_replace($patterns, $vars, file_get_contents($path));
return $result;
}
function maskPattern($value) {
return "{$" . $value . "}";
}
All you PHP must be in a <?php ?> block like this:
<html>
<p><?php echo "{" . $string . "}";?></p>
</html>
If you know the variable to replace in the html you can use the PHP function 'str_replace'. For your script,
$string = "TEST";
$content = file_get_contents('test.html');
$content = str_replace('{$string}', $string, $content);
echo($content);
It's simple to use echo.
<html>
<p>{<?php echo $string;?>}</p>
</html>
UPDATE 1:
After reading so many comments, found a solution, try this:
$string = "TEST";
$template = file_get_contents('themes/default/test.html', FILE_USE_INCLUDE_PATH);
$page = str_replace('{$string}',$string,$template);
echo $page;
I have a sample code:
<?php
$url = 'http://www.youtube.com/watch?v=KTRPVo0d90w';
$pattern = '/http:\/\/www\.youtube\.com\/watch\?(.*?)v=([a-zA-Z0-9_\-]+)(\S*)/i';
$replace = $pattern.'&w=550';
$string = preg_replace($pattern, $replace, $url);
?>
How to result is http://www.youtube.com/watch?v=KTRPVo0d90w&w=550
You can just append using the . operator:
<?php
$url = 'http://www.youtube.com/watch?v=KTRPVo0d90w';
$string = $url.'&w=550';
?>
Use preg_match instead:
<?php
$url = 'http://www.youtube.com/watch?v=KTRPVo0d90w&s=222';
$pattern = '/v=[^&]+/i';
preg_match($pattern, $url, $match);
echo 'http://www.youtube.com/watch?'.$match[0].'&w=550';
?>
Like below?
$url = 'http://www.youtube.com/watch?v=KTRPVo0d90w';
$bit = '&w=550';
echo "${url}${bit}";
Don't get me wrong, I'm not looking to gain any points here, but just thought I would add to this question and include a few options. I love toying with ideas like this every once in a while.
Using jh314's idea to concatenate the strings, thought that this could be used for future use, to actually replace a string inside the video's YouTube number, should the occasion ever present itself.
Such as $number for instance.
<?php
$url = 'http://www.youtube.com/watch?v=';
$number = 'KTRPVo0d90w';
$string = $url.$number.'&w=550';
// Output to screen
echo $string;
echo "<br>";
// Link to video
echo "Click for the video";
?>
The same could easily be done for the video's width.
In this test.php page i have this line of text
server=span.growler.ro&provider=-1&providersSerial=4&country=RO&mobile=0&token=eae5b2c50c123425d9351d8c8ee80b9a27ca3d69f15a669454b937eb
in this other test1.php?id=token page i have this php code runing
<?php
$Text=file_get_contents("./test.php");
if(isset($_GET["id"])){ $id = $_GET["id"];
$regex = "/".$id."=\'([^\']+)\'/";
preg_match_all($regex,$Text,$Match);
$fid=$Match[1][0];
echo $fid; } else { echo ""; } ?>
i need only the token
eae5b2c50c123425d9351d8c8ee80b9a27ca3d69f15a669454b937eb
to be show on test1.php?id=token
if in test.php the token looks like this
token='eae5b2c50c123425d9351d8c8ee80b9a27ca3d69f15a669454b937eb'
it works.
i needet to work from onother web page
$str = 'server=span.growler.ro&provider=-1&providersSerial=4&country=RO&mobile=0&token=eae5b2c50c123425d9351d8c8ee80b9a27ca3d69f15a669454b937eb';
parse_str($str, $vars);
$token = $vars['token'];
using with preg_match will help you .
$string ='server=span.growler.ro&provider=-1&providersSerial=4&country=RO&mobile=0&token=eae5b2c50c123425d9351d8c8ee80b9a27ca3d69f15a669454b937eb';
preg_match('/token=([a-f0-9]+)/i',$string,$matches);
echo $matches[1];
this will return you :
'eae5b2c50c123425d9351d8c8ee80b9a27ca3d69f15a669454b937eb'
I'd recommend you to use preg_match instead of preg_match_all
Try this regex:
$regex = "/&?token=([a-f0-9]*)&?/;
I have a coupon site that display store urls on my store pages. What I want is for only .com at end of each store without showing http:// variations in the beginning
here is my code that displays a store url and I just want domain.com to be displayed instead of http://www.domain.com, also may show as http://domain.com
<p class="store-url"><a href="<?php echo $url_out; ?>" target="_blank"><?php echo $stores_url; ?>
It displays like this because of this function
<div class="store">
<?php // grab the store meta data
$term = get_term_by('slug', get_query_var('term'), get_query_var('taxonomy'));
$stores_url = esc_url(get_metadata(APP_TAX_STORE, $term->term_id, 'clpr_store_url', true));
$dest_url = esc_url(get_metadata(APP_TAX_STORE, $term->term_id, 'clpr_store_aff_url', true));
// if there's a store aff link, then cloak it. else use store url
if ($dest_url)
$url_out = esc_url(home_url(CLPR_STORE_REDIRECT_BASE_URL . $term->slug));
else
$url_out = $stores_url;
?>
What can be done................
Quick and dirty - to demonstrate the possible functions...
<?php
function cleanInputString($inputString) {
// lower chars
$inputString = strtolower($inputString);
// remove whitespaces
$inputString = str_replace(' ', '', $inputString);
// check for .com at the end or add otherwise
if(substr($inputString, -4) == '.com') {
return $inputString;
} else {
return $inputString .'.com';
}
}
// example
$inputStrings = array(
'xyzexamp.com',
'xyzexamp',
'xyz examp'
);
foreach($inputStrings as $string) {
echo('input: '. $string .'; output: '. cleanInputString($string) .'<br />');
}
?>
OUTPUT:
input: xyzexamp.com; output: xyzexamp.com
input: xyzexamp; output: xyzexamp.com
input: xyz examp; output: xyzexamp.com
The "right way" is probably to use the PHP URL-processing:
Break the URL up using http://php.net/manual/en/function.parse-url.php
Remove the scheme element of the resulting array using unset
Build it again using http://www.php.net/manual/en/function.http-build-url.php
This is what preg_replace was made for:
<?php
$http_url = 'http://www.somestore.com/some/path/to/a/page.aspx';
$domain = preg_replace('#^https?://(?:www\.)?(.*?)(?:/.*)$#', '$1', $http_url);
print $domain;
?>
This code will print out
somestore.com
