【PHP】配列を文字列(EDI情報)化

#はじめに
EDI情報作成時に使ったロジックなので備忘録として残します。

#サンプルコード

class TestA
{
	public function __construct()
	{
	    $this->test1 = "00";
	    $this->test2 = "          ";
	    $this->test3 = "00";
	    $this->test4 = "          ";
	    $this->test5 = "GG";
	}
	public function getTest1()
  {
      return $this->test1;
  }
  public function setTest1($test1)
  {
      $this->test1 = $$test1;

      return $this;
  }
	・・・(省略)
}


class TestB
{
	$test;
	
	public function build()
	{
		$this->setTest(new TestA());
		$test = $this->getTest();
		
		$testMessage = 'AAA'.'|'.
		$test->getTest1().'|'.
		$test->getTest2().'|'.
		$test->getTest3().'|'.
		$test->getTest4().'|'.
		$test->getTest5();
		var_dump($testMessage);
	}

	public function getTest()
	{
		return $this->test;
	}
	
	public function setTest()
	{
		$this->test = $test;
		
		return $test;
}

#var_dumpの結果

"AAA|00|          |00|          |GG"
