更新时间：
我正在使用RecursiveIteratorIterator扫描目录以读取index.html文件。
现在，基于Pubname和Pubversion，我试图读取相应的index.html文件，以获取Readability Grade，Readability Score等的值（通过将这些值存储在本地存储中）
如果我分别使用html和JS代码，那么这些值是从本地存储中获取的，但是在我集成到php之后，它就不起作用了。
代码：
<?php
//error_reporting(0);
//Get Pub version
function get_version($path){
$needle = "=";
if(($pos = strpos($path, $needle)) != 0){
$bits = str_split($path, $pos + strlen($needle));
$integer_count = 0;
for($x = 0; $x < strlen($bits[1]); $x++){
if(is_numeric($bits[1][$x])){
$integer_count++;
}else{
break;
}
}
if($integer_count > 0){
$bits = str_split($bits[1], $integer_count);
return $bits[0];
}
}
return -1;
}
$it = new RecursiveDirectoryIterator("C:\Users\Sachin_S2\Desktop\Script");
foreach(new RecursiveIteratorIterator($it,RecursiveIteratorIterator::SELF_FIRST) as $file) {
//IGNORE FILE TYPES
//$filetypes = array("jpg", "png", "pdf", "css", "csv","log","txt");
$htmlfiles = array("html");
$filetype = pathinfo($file, PATHINFO_EXTENSION);
if (in_array(strtolower($filetype), $htmlfiles)) {
// skip dot files while iterating
$it->setFlags(RecursiveDirectoryIterator::SKIP_DOTS);
$files = array($file);
$pathname = $file->getPathname();
print_r($pathname);
$version = get_version($pathname);
if($version > 0){
// use $version to read correct file
include 'html/home.html';
}
echo '*********************************************************************************'.'<br/><br/>';
}
}

//alert(totalwords);
}
});

alert(event.target.error.name);

reader.readAsText(file);
};
});
输出：
在阅读这个php脚本时，我应该能够读取索引html（基于pubname和version的每个文件路径），并获得
Readability_Grade和score等值，这是我无法获得的。最佳答案
首先从字符串中获取版本号，下面是一个方法。
function get_version($path){
$needle = "Pub=";
if(($pos = strpos($path, $needle)) != 0){
$bits = str_split($path, $pos + strlen($needle));
$integer_count = 0;
for($x = 0; $x < strlen($bits[1]); $x++){
if(is_numeric($bits[1][$x])){
$integer_count++;
}else{
break;
}
}
if($integer_count > 0){
$bits = str_split($bits[1], $integer_count);
return $bits[0];
}
}
return -1;
}
然后你就可以这样用了。
foreach ($paths as $path){
$version = get_version($path);
if($version > 0){
// use $version to read correct file
}
}
如果我没听懂你的问题。
免责声明：快速键入，但应该工作。
