分割文件
/* * 分割文件 * 默認大小 2M=10485760/5 */ function file_split($file,$block_size=10485760/5) { $block_info=array(); $size=filesize($file); $i=0; while($size>0){ $block_info[]=array( 'size'=>($size>=$block_size?$block_size:$size), 'file'=>str_replace('.txt', '',$file).'.'.($i++).'.txt' ); $size-=$block_size; } $fp = fopen($file,"rb"); foreach ($block_info as $bi) { $handle = fopen($bi['file'],"wb"); fwrite($handle,fread($fp,$bi['size'])); fclose($handle); unset($handle); } fclose ($fp); unset($fp); }合並文件
/* * 合並文件 * 如果合並后的文件為 CPCUxcp111.flv.0.esplit * 則 file=CPCUxcp111.flv，不包含.x.esplit后綴 * save_file為另存為的文件名 */ function file_combine($file,$save_file=''){ $filename=basename($file); $filepath=dirname($file).'/'; $block_info=array(); for($i=0;;$i++){ if(file_exists($file.'.'.$i.'.esplit') && filesize($file.'.'.$i.'.esplit')>0){ $block_info[]=$file.'.'.$i.'.esplit'; }else{ break; } } if($save_file){ $fp = fopen($save_file,"wb"); }else{ $fp = fopen($file,"wb"); } foreach ($block_info as $block_file) { $handle = fopen($block_file,"rb"); fwrite($fp,fread($handle,filesize($block_file))); fclose($handle); unset($handle); } fclose ($fp); unset($fp); }測試代碼：
file_split('d:/demo.txt');- 1
問題算是解決了，不過這方面有時間還應該研究一下
