ERRO - Call to undefined function mysqli_connect()

<?php include("cabecalho.php") ?>
<?php $nome = $_GET["nome"];$preco = $_GET["preco"];

$conexao = mysqli_connect('localhost', 'root', '', 'loja');

$query = "insert into produtos (nome, preco) values ('{$nome}',{$preco})";
mysqli_query($conexao, $query);

mysqli_close($conexao);

?>

Usando esse código (mesmo da aula), recebo essa resposta qndo registro algum valor no formulário:

"Fatal error: Call to undefined function mysqli_connect() in D:\trabalhos\alura\PHP e MYSQL 1\loja\adiciona-produto.php on line 4"

Estou usando Windows 7 ultimate

Olá Luciano, tudo bom?

O erro está dizendo que não encontrou a função mysqli_connect().

Verifique no seu arquivo php.ini se as linhas "extension=php_mysqli.dll" e "extension=php_mysql.dll" tem ponto e virgula no final. Se sim, retire o ponto e virgula.

Para econtrar o arquivo php.ini, você pode utilizar uma função que exibe toda a configuração do PHP e executar em seu navegador. Se quiser, crie um arquivo com a função phpinfo():

<?php
phpinfo();
?>

Coloque o arquivo em uma pasta acessível pelo seu Apache (a pasta htdocs do xampp) e execute ela no seu navegador. Procure por "configuration file" e lá estará o destino (path) do arquivo de configuração (php.ini) =)

Caso isso não resolva seu problema, me manda uma copia da sua pagina com o phpinfo para que eu possa analisar melhor suas configurações.

obg André, mas as linhas ja estão sem o ponto e vírgula, já lhe envio a cópia...

antes do curso eu tinha o mysql instalado manualmente e não lembro se desinstalei, não pode ser algo relacionado a isso?

Creio que não.

Tem como eu dar uma olhada no seu phpinfo?

como faço para lhe enviar o msmo? perdoe a ignorância...skdsk

Crie um arquivo com a função phpinfo():

<?php
phpinfo();
?>

Coloque o arquivo em uma pasta acessível pelo seu Apache (a pasta htdocs do xampp) e execute ela no seu navegador. Copie tudo é cole aqui =)

Coloquei a função em um arquivo "php-info.php" e colei o mesmo no diretório "C:/xampp/htdocs", abrindo o arquivo no navegador aparecem as configurações do meu PHP, não entendi o que devo colar ou se estou fazendo corretamente...

Copia todas as configurações. Ou seja, todo o conteúdo da página que abriu no navegador e cola aqui pra eu dar uma olhada

Dando uma olhada no configuration file:

Configuration File (php.ini) Path C:\Windows

Loaded Configuration File (none)

Scan this dir for additional .ini files (none)

O php não está encontrando seu arquivo de configuração (php.ini). Existe o arquivo php.ini no diretorio C:\Windows?

Em qual diretório você verificou as extensões php_mysqli.dll e php_mysqli.dll?

Não se esqueça de reiniciar seu servidor apache sempre que realizar uma alteração no php.ini para ter certeza que a alteração foi implementada

esta nesse diretório "C:\Windows\xampp\php"

Verifica pra mim, no seu arquivo php.ini, para qual diretório está apontando a linha extension_dir.

Além disso, da uma olhada na pasta xampp\apache procure pelo arquivo httpd.conf e procure dentro dele a linha PHPIniDir e me diz pra qual diretorio está apontando também.

extension_dir="C:\xampp\php\ext"

E não encontrei esse arquivo "httpd.conf" na pasta do apache.

Procura dentro da pasta xampp\apache\conf

Verifique se o PHPIniDir está apontando para o diretório C:\Windows\xampp\php. Se não, altere para este diretório.

Uma alternativa, caso esta não funcione, é copiar seu arquivo php.ini do diretório C:\Windows\xampp\php e colar no diretório C:\Windows

Espero que resolva =)

o primeiro arquivo não esta no diretório e fiz a segunda alternativa e continua o msmo erro.

Fiz alguns testes por conta que achei na web mas tbm não deram certo, mas fiz um backup e estou testando com o arquivo original do começo da aula, porem sem sucesso ainda..

Você reiniciou o servidor apache após adicionar o arquivo php.ini no diretorio C:\Windows ?

sim, já n sei mais oq faze ksksk, n pode ser algo relacionado aos dados da variavel "$conexao", algum erro de autenticação?

Após eu ter colado o arquivo php.ini no diretório windows notei q meu localhost enviou um monte de erros estranhos antes de funcionar normalmente aki no meu cmd..

Tem como vc me enviar esses erros pra eu dar uma olhada?

solução!

Beleza, ele ja encontrou seu arquivo de configuração! O problema agora está nas dlls do diretório C:\xampp\php\ext\ que não estão sendo reconhecidas pelo seu sistema.

Seu sistema operacional é 32 ou 64bits? Qual versão do xampp vc está utilizando? Este problema é comum quando trabalhamos com versões diferentes.

Tente verificar as versões do seu Apache, do PHP e do Mysql. Certifique-se de que todas sejam 32 bits ou todas sejam 64bits.

Uma alternativa, é você desinstalar tudo e se certificar de que está instalando tudo 32bits.

É 64bits, vou checar isso...

Na página do xampp "https://www.apachefriends.org/pt_br/download.html", só vejo opção para 32bit.

desinstalei tudo denovo e estou instalando novamente...

obrigado André, n percebi q estava tentando conectar o mysql do xampp com o do PHP q eu tinha instalado manualmente.
