我想获得h1标签的所有值，我发现这篇文章:使用php从h1标签获取所有值
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 $titles;
}
echo getTextBetweenTags("http://mydomain.com/","h1");
?>
但是它没有运行，我得到:
注意:数组到字符串的转换在C:'xampp'htdocs'checker'abc.phpon line 14 Array
请帮我修一下。我想得到一个网站的所有h1标签输入数据是该网站的URL。非常感谢!
您正在尝试echo和array，这将导致错误。这个函数有点偏离。例子:
include 'functions/simple_html_dom.php';
function getTextBetweenTags($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);
