What is the best way to select all the text between 2 tags, for instance, the text between all the '<div>' and </div> tags on the page or <div class="topcont"> and </div>. After got the deta I would to have it in an arrray.

Try this

Code:
<?php
$content = "<div class="topcont">your text here</div>";
$pattern = '<div class="topcont">(.+)((\s)+(.+))+</div>';
preg_match($pattern, $content, $matches, PREG_OFFSET_CAPTURE, 3);
print_r($matches);
?>

@Maxoq your question made me remember about a small code that I wrote 10 years ago, it can get content between html tags on whatever sites if wanted.
Here's codes that you can use to get data between tags

PHP:
<?php
header('Content-type: text/html; charset=utf-8');
function getcon($url) {
      $ch = curl_init();
      curl_setopt($ch, CURLOPT_HEADER, 0);
      curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
      curl_setopt($ch, CURLOPT_URL, $url);
      $data = curl_exec($ch);
      curl_close($ch);
      return $data;
}
//$i='';
$arr=array(
 //my array;
);
foreach($arr as $value){		
	$myFile = "$value.txt";	
	$urlGr=str_replace(" ","-",$value);
	$fh = fopen($myFile, 'w') or die("can't open file");
	$br='<br>';
	fwrite($fh, $br);
	$i=21;
	while($i<=186){	
		if($i==1)
		{$ap='';}
		else{
			$ap='page/'.$i.'/';
		}
		//$i = ($j * 16) - 16;
		$content=getcon("URL/$urlGr/$ap");
		//patern="[\s\S\w]*?";
		//$patern="[\s]*([\s\S\w]+?)";
		if(preg_match_all('~<td height="5" valign="top" class="titlestyle"><div align="center"><a href="[\s]*([\s\S\w]+?)" class="titlestyle"~i',$content,$matches)){
	//	  echo '<pre>';
	//	  print_r($matches[1]);
	//	  echo '</pre>';
		}
		$i=$i+1;
	    
	    foreach($matches[1] as $value){
	//	echo $value."<br>";
		$value=$value.$br;
		fwrite($fh, $value);
		}
	}
	fclose($fh);
}
	echo "OK";

?>
Note on this [\s]*([\s\S\w]+?), it will get data and assign into an array, after that you can display it and use it for any purposes.

Hope it helps!
