[Solved] How to gather the url text inside HTML-div via regular expression?

by


You should use DOMDocument and DOMXPath or something like that, but if you want it done with regexp, for your given html this should do the trick:

<?php 

$html_code="<a href="https://stackoverflow.com/napolnye-pokrytiya/" class="category_cart">
    <div class="category_cart__container">
        <div style="background-image: url(\"/media/filer_public/b6/49/b6491a4d-5c0d-4a0f-aa9c-b32ea39912c6/category-2.jpg\')" class="category_cart__thumbnail"></div>
            <div class="category_cart__content">
                <p class="category_cart__title">Напольные покрытия</p>
            </div>
        </div>
</a>

<a href="http://stackoverflow.com/oboi/" class="category_cart">
    <div class="category_cart__container">
        <div style="background-image: url(\'/media/filer_public/93/65/9365c3bc-8649-4d9d-932e-144f16ed535c/category-3.jpg\')" class="category_cart__thumbnail"></div>
            <div class="category_cart__content">
                <p class="category_cart__title">Обои</p>
            </div>
        </div>
</a>';

//it will look for match between url(' and ')
preg_match_all('/url\(\'(.*?)\'\)/', $html_code, $matches_array);
echo '<pre>';
var_dump($matches_array);
echo '</pre>';

$your_array = array();
//matches including url(' and ') are stored in $matches_array[0], excluded in $matches_array[1] so
foreach($matches_array[1] as $match) {

    $your_array[] = $match;

}
echo '<pre>';
var_dump($your_array);
echo '</pre>';
?>

Output:

array(2) {
  [0]=>
  array(2) {
    [0]=>
    string(84) "url('/media/filer_public/b6/49/b6491a4d-5c0d-4a0f-aa9c-b32ea39912c6/category-2.jpg')"

  }

  }
}
