PHP mktemp

Create temporary files and directories in PHP, safely.

Sadly PHP is deficient when it comes to creating temporary files and directories in a safe and secure manner. This library aims to address these short-comings.

Usage

Functions

• Cs278\Mktemp\temporaryFile(string|null $template, string|null $dir)

  Create a temporary file with a supplied template for the name.

  The template should be a string containing a sequence of 3 consecutive X characters, these characters will be replaced with a random component. If this argument is null a default tmp.XXXXXX template will be used.

  The directory should be a path that exists and the user can write to, if this argument is not supplied the default temporary directory will be used.

  A Cs278\Mktemp\Exception\CreateFailedException will be thrown if a file cannot be created.

  use function Cs278\Mktemp\temporaryFile;
  
  var_dump(temporaryFile());
  // /tmp/tmp.P9aLnd
  var_dump(temporaryFile('output.XXXX.pdf'));
  // /tmp/output.oI7b.pdf
  var_dump(temporaryFile(null, '/var/tmp'));
  // /var/tmp/tmp.8uJx
  var_dump(temporaryFile('test.XXX.html', '/var/tmp'));
  // /var/tmp/test.9h2.html

• Cs278\Mktemp\temporaryDir(string|null $template, string|null $dir)

  Create a temporary directory with a supplied template for the name.

  The template should be a string containing a sequence of 3 consecutive X characters, these characters will be replaced with a random component. If this argument is null a default tmp.XXXXXX template will be used.
