Eu tenho o seguinte código:

function PegarTD($conteudo)
{

	return substr(strstr($conteudo,'TouchDown:Rate '),15,4);

}

$td= PegarTD($conteudo);

Mas o sistema funciona apenas para alguns logs. A maioria não pega a informação.

Vale lembrar que o numero em questão MUDA de acordo com os logs!

Alguem saberia resolver ?

Atenciosamente,

";

preg_match( "/TouchDown:Rate (-?[0-9]+)/i", $txt, $matches );

echo $matches[1];
