  • You can give a clearer example?

  • I want to check if the property index in case the public $name is equal to the string "name". I do not want what it contains in name, but rather the content, which is the word name.

  • Explain the purpose because there may be different ways to solve where one can be more suitable than another.

  • The purpose is to write a line in a file, separating by comma. Only in the name that is the first element of the line I n want comma.

I think what you need is the function property_exists. She returns true if a class or object has a certain property and false otherwise.

class Alunos{

   public $nome; 

}

$aluno= new Alunos();

$aluno->nome="Pedro";

if (property_exists("Alunos", "nome"))
{
   echo $aluno->nome, PHP_EOL; // Pedro
}

Or using the object itself:

if (property_exists($aluno, "nome"))
{
   echo $aluno->nome, PHP_EOL; // Pedro
}
