Copying Directory Contents with PHP
Copying the entire contents of a directory to another location in PHP can be a straightforward task, but running into issues like stream not found error can be frustrating. To avoid this, a more explicit approach is required.
To overcome the limitations of using wildcards in the copy() function, a recursive function named recurseCopy() can be employed. This function allows for the replication of multi-level directory structures and their contents.
The recurseCopy() function takes three parameters:
The function iterates through the files and subdirectories of the source directory. If a file is encountered, it is directly copied to the destination directory. If a subdirectory is found, the function recursively calls itself to copy its contents into the corresponding subdirectory under the destination directory.
Here's a sample PHP code that utilizes the recurseCopy() function:
<code class="php">function recurseCopy(string $sourceDirectory, string $destinationDirectory, string $childFolder = ''): void { $directory = opendir($sourceDirectory); if (is_dir($destinationDirectory) === false) { mkdir($destinationDirectory); } if ($childFolder !== '') { if (is_dir("$destinationDirectory/$childFolder") === false) { mkdir("$destinationDirectory/$childFolder"); } while (($file = readdir($directory)) !== false) { if ($file === '.' || $file === '..') { continue; } if (is_dir("$sourceDirectory/$file") === true) { recurseCopy("$sourceDirectory/$file", "$destinationDirectory/$childFolder/$file"); } else { copy("$sourceDirectory/$file", "$destinationDirectory/$childFolder/$file"); } } closedir($directory); return; } while (($file = readdir($directory)) !== false) { if ($file === '.' || $file === '..') { continue; } if (is_dir("$sourceDirectory/$file") === true) { recurseCopy("$sourceDirectory/$file", "$destinationDirectory/$file"); } else { copy("$sourceDirectory/$file", "$destinationDirectory/$file"); } } closedir($directory); } $sourceDirectory = 'my_source_dir'; $destinationDirectory = 'my_destination_dir'; recurseCopy($sourceDirectory, $destinationDirectory);</code>
This code will recursively copy the contents of the my_source_dir directory to the my_destination_dir directory, preserving the directory structure and file contents.
