Question

这是上传和打印文本文件。现在，这个txt文件包含预订人员的详细信息，并通过电子邮件发送，如下所示：

some text (always the same)
= ================
text again
name   : Mr F Someone
address: Somewhere
...
...
more same text

问题是没有分隔符。我想抓住像“先生”，“F”，“某人”这样的数据......然后把它们中的每一个都放在一个表格的输入字段中。我试过这样的事情：

    $section_a = file_get_contents($up_folder, NULL, NULL, 508, 2);
    echo '<input type="text" name="Title" value="'.$section_a.'">';

但是如果它是“Miss”而不是“Mr”那么它就是一个问题，与名称的长度相同，等等。并且文件中有多个“预订”。那么，有没有办法从文件中获取每个预订的详细信息，以便每次都放在一个表单中？

<?php
    if($_FILES['userfile']['error'] > 0){
        echo 'Houston, we have a problem: ';
        switch($_FILES['userfile']['error'])
        {    
            case 1: echo 'file too big'; break;
            case 2: echo 'file too big'; break;
            case 3: echo 'incomplete upload'; break;
            case 4: echo 'uplad error'; break;
        }
        exit;
    }
    if($_FILES['userfile']['type'] != 'text/plain'){
        echo 'Ooh noes! File is not plain text dude!';
        exit;
    }
    $up_folder = 'upload/'.$_FILES['userfile']['name'];
    if(is_uploaded_file($_FILES['userfile']['tmp_name'])){
        if(!move_uploaded_file($_FILES['userfile']['tmp_name'], $up_folder)){
            echo 'cannot move file';
            exit;
        }
    }
    else{
        echo 'error: ';
        echo $_FILES['userfile']['name'];
        exit;
    }
    echo 'file upload successful<br>';

    $fp = fopen($up_folder, 'r');
    $contents = fread($fp, filesize($up_folder));
    fclose($fp);

    $contents = strip_tags($contents); 
    $fp = fopen($upfile, 'w');
    fwrite($fp, $contents);
    fclose($fp);

    echo 'Uploaded file content: <br> <br>';
    echo $contents;
?>

Answer 1

$fetch = ['name','address'];
$output = [];

$fp = fopen($file, 'r');
while(!feof($fp) && count($output) !== count($fetch)) {
    $line = fgets($line);
    list($prefix, $value) = explode(':', $line, 2);
    $prefix = strtolower(trim($prefix));
    foreach($fetch as $f) {
        if($prefix === $f) {
            $output[$f] = trim($value);
            break;
        }
    }
}
fclose($fp);

print_r($output);
