I need to extract the value of the attributes of a html tag that is defined as a php variable:
[video src="http://localhost/video.mp4" poster="http://localhost/thumb.jpg" preload="none"][/video]
values of src and poster should be separated and cast to array
if your text is a php variable, you can use preg_match :
<?php
$text = '[video src="http://localhost/video.mp4" poster="http://localhost/thumb.jpg" preload="none"][/video]';
preg_match('/src=\"([^\"]+)\"/si', $text, $src);
preg_match('/poster=\"([^\"]+)\"/si', $text, $poster);
$array['src'] = $src[1];
$array['poster'] = $poster[1];
print_r($array);
?>
also you can use simplehtmldom
You can use an html parser for this. See this one: http://simplehtmldom.sourceforge.net/.
$html = str_get_html('<video src="http://localhost/video.mp4" poster="http://localhost/thumb.jpg" preload="none"></video>');
foreach($html->find('video') as $element)
{
$array['src'] = $element->src;
$array['poster'] = $element->poster;
}

Find scripts in html source by DomDocument and then variable declaration by regex
$DOM = new DomDocument();
$DOM->loadHTML( $output);
$res = [];
$scripts = $DOM->getElementsByTagName('script');
$lnt = $scripts->length;
for($i=0; $i < $lnt; $i++) {
preg_match_all('/var\s+(\w+)\s*=\s*(\d+)\s*;/', $DOM->saveHtml($scripts->item($i)), $m);
$res = array_merge($res, array_combine($m[1], $m[2]));
}
print_r($res);

Content is
<html>...<div id="endText" class="end-text" jcid="8311"><p>Hello</p>World<div class="ep-source cDGray"></div></div>...</html>
How to match
<p>Hello</p>World<div class="ep-source cDGray"></div>
Thank you!
#Rizier123
$content = '';
if(preg_match('/"endText".+?>.+?(?=<div.+?class="ep-source cDGray">)/i', $html, $contents) &&
preg_match('/(?<=>).+/i', $contents[0], $contentss))
{
$content = iconv('GBK', 'UTF-8', $contentss[0]);
return rtrim('OK' . "\t" . $content);
}
else
{
return rtrim('SKIP' . "\t" . 'NO_CONTENT');
}
This method can be used temporary, can't solve the problem.
Just match and remove the first-level div.
Regex (matches the opening div, saves its innards, and matches the last closing div):
/^<div id="endText"[^>]+>(.*?)<\/div>$/ism
PHP example:
preg_match('/^<div id="endText"[^>]+>(.*?)<\/div>$/ism', $html, $contents);
echo $contents[1];
// returns: <p>Hello</p>World<div class="ep-source cDGray"></div>
Adding the id attribute to the regex helps to specify that particular div

I have some form in a variable. I have some input fields with names. How can I get all name="" from that string?
Now I'm trying this:
preg_match_all ('/(name="(.*?"))\d/s', $ki, $matches1);
But not working well. It gives me just a few and it gives me a lots of unnececary informations.
Try with this regex:
preg_match_all( '/name\s*=\s*(?|"(.*?)"|\'(.*?)\')/', $ki, $matches1 );
You can also do this using array.
i.e. By using explode method
$content='name="name1" other example text name="name2" other example text name="name3" ';
$finalResult=array();
function getBetweenAll($content,$start,$end)
{
$res = explode($start , $content , 2);
if(isset($res[1]) && $res[1]!='' )
{
$value = explode($end , $res[1] , 2);
global $finalResult;
$finalResult[]=$value[0];
if(isset($value[1]) && $value[1]!='')
{
$content=$value[1];
getBetweenAll($content,$start,$end);
}
}
}
$start='name="';
$end='"';
getBetweenAll($content,$start,$end);
echo "<pre>";
print_r($finalResult);
echo "</pre>";

I am receiving an external file with strings, I have no control over that file but I receive special characters as this (i think it's unicode?) sequence \u00e1n.
Is there anyway to convert this kind of char sequences to their "readable" counterparts?
Thanks!
EDIT:
I am calling a url that gives me a list with names of persons:
Tom\u00e1nsson\n
Eriksen\n
Gilverto\n
I am reading the names and showing them in my site.
EDIT
Now, I've figured out the correct, working answer based on the article I found. Here is it:
function unicode2utf8($str) {
$a=json_decode(str_replace("\n","<br>",'["'.$str.'"]'));
return str_replace("<br>","\n",$a[0]);
}
PHP:
echo unicode2utf8("Tom\u00e1nsson\n Eriksen\n Gilverto\n");
Output:
Tománsson
Eriksen
Gilverto
ORIGINAL
I've found an article about the same problem here ( http://www.welefen.com/php-unicode-to-utf8.html )
The solution is the following function
function unicode2utf8($str){
if(!$str) return $str;
$decode = json_decode($str);
if($decode) return $decode;
$str = '["' . $str . '"]';
$decode = json_decode($str);
if(count($decode) == 1){
return $decode[0];
}
return $str;
}
I've tried it with
echo unicode2utf8("\u00e1");
Output:

Is it possible to get the text between <p></p> tags and set this in a variable?
<p>blabla</p> So i would like to get the text "blabla" and set this into a php variable so the variable would have the text value like this:.
<?$test = blabla;?>
Try:
$html = "<p>blabla</p>";
$dom = new DOMDocument;
$dom->loadXML($html);
$arr = $dom->getElementsByTagName('p');
foreach ($arr as $value) {
echo $value->nodeValue; // result => blabla
}
There are many methods which can be used based on your needs so take a look on documentation
DOMDocument
You can use this function, it is self explanatory:
function getTextBetweenTags($string, $tagname)
{
$pattern = "/<$tagname>(.*?)<\/$tagname>/";
preg_match($pattern, $string, $matches);
return $matches[1];
}
?>
