PHP implements file copy

Use fread fwrite fclose

1.

$inputDir="D:/ccc.txt";
$outputDir="D:/ddd.txt";
//是否存在输出目录
if(!file_exists($outputDir)){
$dirs=fopen($outputDir,'w');
fclose($dirs);
}
$handle=fopen($inputDir,'r');
$c
fclose($handle);
$outResouse=fopen($outputDir,'w');
fwrite($outResouse,$content);
fclose($outResouse);

2.

<pre name="code" class="php">$inputDir="D:/ccc.txt";
$outputDir="D:/ddd.txt";

$c
$handle2=fopen($inputDir,'r');
$outResouse2=fopen($outputDir,'w');
while (!feof($handle2)) {
  $content2 .= fread($handle2, 10);
}
fwrite($outResouse2,$content2);
fclose($handle2);
fclose($outResouse2);

3.

<pre name="code" class="php">$inputDir="D:/ccc.txt";
$outputDir="D:/ddd.txt";

$c
$handle3=fopen($inputDir,'r');
$outResouse3=fopen($outputDir,'w');
$i=0;
while (!feof($handle3)) {
  $content3 = fread($handle3, 10);
fseek($outResouse3,$i*10);
fwrite($outResouse3,$content3);
$i++;
}
fclose($handle3);
fclose($outResouse3);

4.

$c
$handle4=fopen($inputDir,'r');
$outResouse4=fopen($outputDir,'w');
while(($c
fwrite($outResouse4,$content4,10);
}
fclose($handle4);
fclose($outResouse4);

The above has introduced the implementation of file copying in PHP, including aspects of it. I hope it will be helpful to friends who are interested in PHP tutorials.
