我想获得h1标签的所有价值,我发现了这篇文章:getting all values from h1 tags using php
然后我尝试使用:
<?php
include "functions/simple_html_dom.php";
function getTextBetweenTags($string, $tagname) {
// Create DOM from string
$html = str_get_html($string);
$titles = array();
// Find all tags
foreach($html->find($tagname) as $element) {
$titles[] = $element->plaintext;
}
return $titles;
}
echo getTextBetweenTags("http://mydomain.com/","h1");
?>
但它没有运行而且我得到了:
注意:C:\ xampp \ htdocs \ checker \ abc.php中的数组到字符串转换 在第14行数组
Plz帮我修复它。我想获得一个带有输入数据的网站的所有h1标签是该网站的URL。非常感谢!

您正试图echo
array
,这将导致错误。功能有点偏。例如:
include 'functions/simple_html_dom.php';
function getTextBetweenTags($url, $tagname) {
$values = array();
$html = file_get_html($url);
foreach($html->find($tagname) as $tag) {
$values[] = trim($tag->innertext);
}
return $values;
}
$output = getTextBetweenTags('http://www.stackoverflow.com/', 'h1');
echo '<pre>';
print_r($output);
