除了一个小细节外,我的一切工作正常。我需要弄清楚如何获取我的HTML模板中的静态占位符变量,以便我可以用从TXT文件中提取的内容替换它们。
这是我的模板代码:
<!DOCTYPE html>
<html>
<head>
<title>{PAGE_TITLE}</title>
</head>
<body>
{PAGE_TITLE} - {PAGE_AUTHOR} - {PAGE_DATE}
{PAGE_CONTENT}
</body>
</html>

我回顾了这个问题PHP - parsing a txt file,并尽我所能。
我正在PHP中创建一个简单的,非常小的静态站点生成器,用于教育目的。我有一个目录,只有一个PHP文件,所有代码都在这里(HTML模板除外),它将扫描当前目录中的任何txt文件并确定是否有多个这样的循环可用于处理每个文件。
我的txt文件的结构如下:
TITLE
AUTHOR
DATE
Text starts here...
我坚持从文件中提取TITLE,AUTHOR,DATE和文本内容的部分,并将它们存储在正确的变量中,以便将信息传递给HTML模板进行处理。 / p>
我还希望设置它,所以当有换行/返回时,它会在该文本块中附加一个HTML段落标记。
这是我到目前为止PHP代码的代码:
<?php
$files = glob("*.txt"); // Scan directory for .txt files
// Check that there are .txt files in directory
if ($files !== false) {
$numberOfFiles = count($files); // Count number of .txt files in directory
// Check if number of files is greater than one
if ($numberOfFiles > 1) {
// Advanced loop will go here to process multiple txt files
} else {
$file_handle = fopen ($files[0], "r"); // Open file
// Loop through file contents line-by-line
while (!feof ($file_handle)) {
$file = file_get_contents($files[0]); // Get file contents
$rows = explode ("\n", $file); // Count number of rows in file
// Need to pull TITLE, AUTHOR, and DATE from txt file
// Here's where I need the rest of the file's content to be parsed into paragraph blocks for the html template
break; // Break loop after one run
}
fclose ($file_handle); // Close file connection
}
}
?>
答案 0 :(得分:3)
您可以逐个从文件中获取行,而不是获取整个文件,然后单独格式化它们并将它们放入变量中,以便在页面上回显。然而,Dontfeedthecode提出的方法迄今为止更优越,更高效,我已经撤回原文,并希望他会赞同我对他的想法所做的一切。
<?php
$files = glob("*.txt"); // Scan directory for .txt files
// Check that there are .txt files in directory
if ($files !== false) {
$numberOfFiles = count($files); // Count number of .txt files in directory
// Check if number of files is greater than one
if ($numberOfFiles > 1) {
// Advanced loop will go here to process multiple txt files
} else {
$text_array = array();
$file_handle = fopen ($files[0], "r"); // Open file
$text_array = stream_get_contents($file_handle);
$text_array = explode("\n", $text_array);
// get the top three lines
$page_title = trim($text_array[0]);
$all_lines = '<p>' . trim($text_array[0]) . ' - ' . trim($text_array[1]) . ' - ' . trim($text_array[2]) . '</p>';
// delete the top four array elements
$text_array[0] = $text_array[1] = $text_array[2] = $text_array[3] = '';
// get the remaining text
$text_block = trim(implode($text_array));
fclose ($file_handle); // Close file connection
} // endifs for first if(... statements
}
?>
HTML输出:
<!DOCTYPE html>
<html>
<head>
<title><?php echo $page_title; ?></title>
</head>
<body>
<?php echo $all_lines . "\n" . '<p>' . $text_block .'</p>'. "\n"; ?>
</body>
</html>
A variable ready to print to file:
<?php
$print_to_file = '<!DOCTYPE html>
<html>
<head>
<title>' . $page_title . '</title>
</head>
<body>' . "\n" . $all_lines . "\n" . '<p>' . $text_block .'</p>'. "\n" .
' </body>
</html>';
echo $print_to_file;
?>
HTML在变量中看起来有点偏移,但在打印时会出现。
最后,一个版本为文本的每一行添加<p>
标记。
<?php
$files = glob("*.txt"); // Scan directory for .txt files
// Check that there are .txt files in directory
if ($files !== false) {
$numberOfFiles = count($files); // Count number of .txt files in directory
// Check if number of files is greater than one
if ($numberOfFiles > 1) {
// Advanced loop will go here to process multiple txt files
} else {
$text_array = array();
$file_handle = fopen ($files[0], "r"); // Open file
$text = stream_get_contents($file_handle);
// get the top three lines
$text_array = explode("\n", $text);
$page_title = trim($text_array[0]);
$all_lines = '<p>' . $text_array[0] . ' - ' . $text_array[1] . ' - ' . $text_array[2] . '</p>';
// set up something to split the lines by and add the <p> tags
$text_array = str_replace("\n","</p>\nxxx<p>", $text);
$text_array = explode("xxx", $text_array);
// delete the top four array elements
$text_array[0] = $text_array[1] = $text_array[2] = $text_array[3] = '';
// get the remaining text
$text_block = trim(implode($text_array));
}
}
?>
此版本可以使用与上面相同的html / php块
