I'm creating an application with React, and the backend part with PHP

I have ajax request:

pesquisaCliente(e) {

e.preventDefault();
$.ajax({
    url:'http://192.168.0.109/prontaentrega/pesquisaCliente.php',
    contentType:'application/json',
    datType:'json',
    type:'post',
    data:JSON.stringify({nome:this.state.nome}),
    success: function(cli) {

    }.bind(this)
});

}

and in the PHP part:

<?php
header('Access-Control-Allow-Origin: *'); 
header("Access-Control-Allow-Headers: Content-Type");

include 'conexao.php';

echo $_POST['nome'];

?>

But it does not show the $_POST['nome]' value

Note: You are not giving any errors because they are different servers.

Your problem is in the data format sent to the server. In the ajax request you say that the contentType is application/json , so PHP will not populate this in the $_POST variables, it's up to you to read what was posted and execute json_decode on the information.

Your PHP file would look like:

<?php

    header('Access-Control-Allow-Origin: *'); 
    header("Access-Control-Allow-Headers: Content-Type");

    include 'conexao.php';
    $dados = json_decode(file_get_contents("php://input")); // Assim você lê o faz o decode
    echo $dados->nome; // Acessa a propriedade nome do objeto json postado.

?>
