Dont Parse Simple HTML DOM on php 7.1

Question

I'm running simple html dom on php 7.1.

But the first line I can not parse html

My code

<?php
include 'simple_html_dom.php';

$html = file_get_html('http://google.com');

echo $html;
?>

The page displays nothing (white background) with the above code.

But the below code but runs:

<?php
include 'simple_html_dom.php';
//base url
$base = 'https://google.com';
$curl = curl_init();
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_URL, $base);
curl_setopt($curl, CURLOPT_REFERER, $base);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
$str = curl_exec($curl);
curl_close($curl);
// Create a DOM object
$html_base = new simple_html_dom();
// Load HTML from a string
$html_base->load($str);
echo $html_base;
$html_base->clear(); 
unset($html_base);
?>

Then, I try to get img with class below code with above code but no working:

Image html to get:

<div class="product_thumb">
<a title="Me Before You" class="image-border" href=/me-before-you-a-novel-movie-tie-in-p69988.html">
<img class="   pict lazy-img" id="det_img_00069988" 
src="/images/thumbnails/product/115x/222614_me-before-you-a-novel-movie-tie-
in.jpg">
</a></div>

My Simple HTML DOM, All dont working (get no html on may page)

//* Find all images 1st code
foreach($html_base->find('img[class=   pict lazy-img]') as $element) 
   echo '<img src="' . $element->src . '" />' . '<br>';
//* Find all images 2nd code
foreach($html_base->find('img[class=   pict lazy-img]',0) as $element) 
   echo '<img src="' . $element->src . '" />' . '<br>';
//* Find all images 3rd code
foreach($html_base->find('img[class$=pict lazy-img]',0) as $element) 
   echo '<img src="' . $element->src . '" />' . '<br>';
//* Find all images 4th code
foreach($html_base->find('img[class$=pict lazy-img]',0) as $element) 
   echo '<img src="' . $element->src . '" />' . '<br>';

Answer 1

file_get_html change in simple_html_dom include file needs to be changed. See below, it worked for me. See link https://sourceforge.net/p/simplehtmldom/bugs/161/

Since PHP 7.1 it is possible to interpret negative offset. The default Value of offset have to be changed from -1 to 0 .

function file_get_html($url, $use_include_path = false, $context=null, $offset = 0, $maxLen=-1, $lowercase = true, $forceTagsClosed=true, $target_charset = DEFAULT_TARGET_CHARSET, $stripRN=true, $defaultBRText=DEFAULT_BR_TEXT, $defaultSpanText=DEFAULT_SPAN_TEXT)

I escaped this by changing "simple_html_dom.php" file in method "parse_slector()" (in line 386) as

$pattern = "/([\w\-:\*]*)(?:\#([\w\-]+)|\.([\w\-]+))?(?:\[@?(!?[\w\-]+)(?:([!*^$]?=)[\"']?(.*?)[\"']?)?\])?([\/, ]+)/is";

and in method "read_tag()" (in line 722)

if (!preg_match("/^[\w\-:]+$/", $tag)) {
...
}

the trick is adding backslash before "-" on the pattern
