У меня есть HTML-контент, подобный этому 

<p><b style="margin: 0px; padding: 0px; border: 0px; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-stretch: inherit; line-height: inherit; font-family: Lato, Arial, Helvetica,

Я хочу заменить все теги img на тег a, который я использую PHP DOMDocument. 

$dom = new DOMDocument();
$dom->loadHTML($content);
foreach ($dom->getElementsByTagName('img') as $img) {
    $src = urldecode($img->getAttribute('src'));
    if (!empty($src)) {           
        $link = $dom->createElement('a', "Image");          
        $link->setAttribute('target', '_blank');
        $link->setAttribute('href', $src);
        $img->parentNode->replaceChild($link, $img);
    }
}
$dom->saveHTML();

Этот код заменит толькотолько первый img.Как я могу заменить все img на a тег.

это вывод, который я получаю 

<p><b style="margin: 0px; padding: 0px; border: 0px; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-stretch: inherit; line-height: inherit; font-family: Lato, Arial, Helvetica,

Вы можете использовать preg_replace функция 

  $pattern = '(<img)';
  $replacement = '<a ';
  $pattern2 = '(src=)';
  $replacement2 = 'href= ';

  $subject = Your text
  $temp = preg_replace($pattern, $replacement, $subject, -1 );
  echo preg_replace($pattern2, $replacement2, $temp, -1 );

Проблема, с которой класс DOMDocument в PHP превосходит

=> Попробуйте 

    <?php
    $content = '<p><b style="margin: 0px; padding: 0px; border: 0px; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-stretch: inherit; line-height: inherit; font-family: Lato, Arial, Helvetica,

    $dom = new DOMDocument();
    $dom->loadHTML($content);

    foreach ($dom->getElementsByTagName('img') as $img) {

        echo $content;
    }

     $content = $dom->saveHTML();
?>

ИЛИ

=> использовать это для динамического пути img .. 

<?php

Это тот случай, когда вы изменяете содержимое документа, который вы повторяете над (ваш список тегов в $dom->getElementsByTagName('img')), тогда это вызывает проблемы.Чтобы обойти это, используйте XPath, который создает новый список узлов (запрос XPath //img означает найти любой тег <img>), а затем выполните итерацию по этому ... 

$dom = new DOMDocument();
$dom->loadHTML($content);

$xp = new DOMXPath($dom);
foreach ($xp->query("//img") as $img) {
...
