我想解析一些HTML文件,我上传到我的虚拟主机。当我尝试这(与在那里的最后一个回声只是为了看看它的工作原理):解析通过PHP,回声不工作
<?php
//a URL you want to retrieve
$my_url = 'http://pointstreak.com/prostats/standings.html?leagueid=49&seasonid=12983';
$html = file_get_contents($my_url);
$dom = new DOMDocument();
$dom->loadHTML($html);
$xpath = new DOMXPath($dom);
//Put your XPath Query here
$my_xpath_query = "//div[@id='statscontainer']/table/tr/td/table[@class='tablelines']/tr/td";
$result_rows = $xpath->query($my_xpath_query);
// Create an array to hold the content of the nodes
$standingsArray = array();
//here we loop through our results (a DOMDocument Object)
foreach ($result_rows as $result_object){
$standingsArray[] = $result_object->childNodes->item(0)->nodeValue;
}
// Remove the first 12 observations from $standingsArray (table headers)
for ($i = 0; $i < 12; $i++) {
unset($standingsArray[0]);
$standingsArray = array_values($results_rows);
}
// Remove the 12 observations at index 96 (table headers)
for ($i = 0; $i < 12; $i++) {
unset($standingsArray[96]);
$standingsArray = array_values($results_rows);
}
foreach ($standingsArray as $arrayValue) {
echo $arrayValue;
}
echo “HEYHEY”;
?>
在我的网页的输出是: “HEYHEYâ€
但是,如果我改线
foreach ($standingsArray as $arrayValue) {
echo $arrayValue;
}
到:
foreach ($standingsArray as $arrayValue) {
echo "$arrayValue";
}
那么即便是 “ “嗨嗨” 消失了,我拥有的只是一个空白的网页。

在打开'<?php'标记error_reporting(E_ALL)后立即在文件顶部添加错误报告; ini_set('display_errors',1);'就像@Jite说的那样。 –
这不是一个PHP错误。你有一个字符集不匹配。例如将utf-8文本转储到iso-8859显示环境中。 –
