How to parse the return of the __getFunctions() class Soapclient method

Question

I consulted a Web Service using the class SoapClient of PHP and the method __getFunctions() to list the services provided by this Web Service.

I got the return below:

Array
(
    [0] => ConsultarResponse Consultar(ConsultarRequest $ConsultarRequest)
    [1] => ConsultarTipoResponse, ObjResponse ConsultarTipo(ConsultarTipoRequest $ConsultarTipoRequest)
)

How do I parse to get the word that comes before relatives? The idea would be to ignore everything and take only the occurrence that comes to the left of the relatives.

The return would have to be:

• Constular
• Consultartipo

With a well structured ER, you do it in a few lines.

First of all, it is important to understand that until the nomenclature of methods follows a regular expression:

'^[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*$'

From this, you can expand the regular expression to search whenever there is a method name, compatible with the above regular expression, between a blank space and the opening of a parenthesis:

'\s[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*\(/'

As you want to extract only the method name, it is important to include in a group (which I nomarei of method):

'\s(?P<method>[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*)\(/'

And the code for use:

$stringList = [
    'ConsultarResponse Consultar(ConsultarRequest $ConsultarRequest)',
    'ConsultarTipoResponse, ObjResponse ConsultarTipo(ConsultarTipoRequest $ConsultarTipoRequest)'
];

$matches = [];

foreach($stringList as $string) {   
    preg_match(
        '/\s(?P<method>[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*)\(/',
        $string,
        $matches
    );

    printf("Método: %s <br />" , $matches['method']);
}

Exit:

Método: Consultar 
Método: ConsultarTipo

You can use the function strpos() to find the position of the first space and of the open prenhesis, with this it is possible to determine which section should be 'cropped' with the function substr() that is to begin at after the occurrence of space ($espaço+1) and copies N characters this done with $parentese - $espaco -1.

$arr = array('ConsultarResponse Consultar(ConsultarRequest $ConsultarRequest)',
             'ConsultarTipoResponse ConsultarTipo(ConsultarTipoRequest $ConsultarTipoRequest)'
            );

foreach($arr as $item){
    $espaco = strpos($item, ' ');
    $parentese = strpos($item, '(');
    echo substr($item, $espaco+1, $parentese - $espaco -1) .'<br>';
}

You can use a regex with a group ($m[1]) to capture exactly what is between the space (\s+) and parenthesis.

foreach($arr as $item){
    preg_match('/\s+(\w+)\(/', $item, $m);
    echo $m[1] .'<br>';
}

By the model presented, your query would be something like this:

$parametro = 'Sua consulta';

$client = new SoapClient('http://path/seuwebservice.wsdl');
$client->ConsultarResponse->Consultar($parametro);
$client->ConsultarTipoResponse->ConsultarTipo($parametro);

To make a parse of it, it would be basically like this:

$return  = $client->__getFunctions();

list($use, $notUse) = explode('(', $return[0]);
list($ConsultarResponse, $Consultar) = explode(' ',$use);
//primeiro
echo $Consultar;

list($useTwo, $notUseTwo) = explode('(',$return[1]);
list($ConsultarTipoResponse, $ConsultarTipo) = explode(', ObjResponse ', $useTwo);
//segundo
echo $ConsultarTipo;
