在foreach循环中声明函数

Question

I am trying to create a foreach loop which would visit a link from an array of links and get contents from each of the visited websites.

But when I try to run it:

<?php
    require('simple_html_dom.php');

    // Create DOM from URL or file
    $html = file_get_html('http://www.forgolf.cz/index.php/novinky.html');

   $titles = [];
    $links = [];
    $img_src = [];
    $paragraph = [];

   foreach ($html->find('h2 a') as $title) {

       $links[] = $title->getAttribute('href');
        $titles[] = $title->innertext;
    }

   foreach ($html->find('.item-inner p img') as $img) {
        $img_src[] = $img->getAttribute('src');
    }


   foreach ($links as $link) {
        require('simple_html_dom.php');

        $html = file_get_html('http://www.forgolf.cz'. $link);
        foreach ($html-find('.item-page p') as $p) {
            if (is_string($p))
                $paragraph[] = $p->innertext;
        }
    }
?>

I get Fatal error: Cannot redeclare file_get_html()

And when I dont include the require('simple_html_dom.php');

I get: Fatal error: Uncaught Error: Call to undefined function find()

So I am realy confused.

Anyone got any ideas how to repaire this.

Answer 1

please change code few line

 foreach ($links as $link) {
        require('simple_html_dom.php'); **// here** comment line like **//require('simple_html_dom.php');**

        $html = file_get_html('http://www.forgolf.cz'. $link);
        foreach ($html-find('.item-page p') as $p) {
            if (is_string($p))
                $paragraph[] = $p->innertext;
        }
    }
?>

Finally Code

    <?php
require ('simple_html_dom.php');

// Create DOM from URL or file

$html = file_get_html('http://www.forgolf.cz/index.php/novinky.html');
$titles = [];
$links = [];
$img_src = [];
$paragraph = [];

foreach($html->find('h2 a') as $title)
    {
    $links[] = $title->getAttribute('href');
    $titles[] = $title->innertext;
    }

foreach($html->find('.item-inner p img') as $img)
    {
    $img_src[] = $img->getAttribute('src');
    }

foreach($links as $link)
    {

    // require('simple_html_dom.php');

    $html = file_get_html('http://www.forgolf.cz' . $link);
    foreach($html->find('.item-page p') as $p)
        {
        if (is_string($p)) $paragraph[] = $p->innertext;
        }
    }

?>
