PHP - 四级单词lrc文件解析为txt

<?php
	header(‘Content-type:text/html; charset="utf-8"‘);
	
	//文件存在于桌面
	$fromfilename = ‘1.lrc‘;//原始文件名称。
	$tofilename = ‘1_txt.txt‘;//转换后，存放至…………
	
	$handle = @fopen("C:\\Users\\Administrator\\Desktop\\".$fromfilename,"r");
	$fh = fopen("C:\\Users\\Administrator\\Desktop\\".$tofilename, "a");
	
	$i = 0;
	
	if ($handle) {
		while (($buffer = fgets($handle, 4096)) !== false) {
			//进行操作
			if(!($i <= 4)) {
				if($i == 5 || $i == 6) {
					//echo preg_replace (‘/\[([\s\S]*)\]/‘, ‘*‘, $buffer).PHP_EOL;
					fwrite($fh, preg_replace (‘/\[([\s\S]*)\]/‘, ‘*‘, $buffer).PHP_EOL);
