php的文件读取和写入似乎对未知格式的文件不管用
<br /><?php<br />$file="宋1.mp3.part1";<br />$file1="宋2.mp3.part1";<br />$file2="宋3.mp3.part1";<br />$fp = fopen($file, "a");<br />$fp1 = fopen($file1, "r");<br />$fp2 = fopen($file2, "r");<br />// if(!$fp1) echo "aa";<br />// return;<br />//fseek(fp, 0, SEEK_END);<br />$index=0;<br /> while(!feof($fp1)){//测试文件指针是否到了文件结束的位置 <br /> $content=fread($fp1,10); <br /> if(fwrite($fp,$content)==false)<br /> echo "不能写入到文件 $filename"; <br /> $index++;<br /> echo $index;<br /> } <br /> $index=0;<br /> while(!feof($fp2)){//测试文件指针是否到了文件结束的位置 <br /> $content=fread($fp2,10); <br /> fwrite($fp,$content); <br /> $index++;<br /> echo $index;<br /> } <br /> fclose($fp); <br /> fclose($fp1); <br /> fclose($fp2); <br /> rename ($file, "a.mp3"); <br /> echo "ok";<br />?><br /><br />$str="宋1.txt";<br />$str=iconv("utf-8", "GBK", $str);//注释掉就会失败<br />$fp = fopen($str, "a");<br />if(fwrite($fp,"losasds")!==false) echo "ok";<br />else echo "fail";<br />fclose($fp);<br />
