Work with google urls

SERPS gives you the tools you need to create urls for google.

Back to the general google documentation.

The class GoogleUrl offers many convenient tools to work with google urls. See how it works with examples.

Create an url

The url builder has the required tools to build an url from scratch.

    use Serps\SearchEngine\Google\GoogleUrl;

    $googleUrl = new GoogleUrl();
    $googleUrl->setSearchTerm('simpsons');
    $googleUrl->setLanguageRestriction('lang_en');
    echo $googleUrl->buildUrl();
    // https://google.com/search?q=simpsons&lr=lang_en

Url from a string

It's also possible to parse an an existing google url string to an url object.

    use Serps\SearchEngine\Google\GoogleUrl;

    $googleUrl = GoogleUrl::fromString('https://google.com/search?q=simpsons');
    echo $googleUrl->getSearchTerm();
    // simpsons

Additionally you can continue to manipulate this url

    $googleUrl->setLanguageRestriction('lang_en');
    echo $googleUrl->buildUrl();
    // https://google.com/search?q=simpsons&lr=lang_en

Google domain

By default an url is generated for google.com but you can choose any domain of your choice:

    use Serps\SearchEngine\Google\GoogleUrl;

    $googleUrl = new GoogleUrl('google.fr');
    $googleUrl->setSearchTerm('simpsons');
    echo $googleUrl->buildUrl();
    // https://google.fr/search?q=simpsons

It's also possible to modify it latter

    $googleUrl->setHost('google.de');
    echo $googleUrl->buildUrl();
    // https://google.de/search?q=simpsons

Add and remove parameters

It's possible to add or remove parameters

    use Serps\SearchEngine\Google\GoogleUrl;

    $googleUrl = new GoogleUrl();
    $googleUrl->setParam('q', 'simpsons');
    $googleUrl->setParam('start', 11);
    echo $googleUrl->buildUrl();
    // https://google.com/search?q=simpsons&start=11

    $googleUrl->removeParam('start');
    echo $googleUrl->buildUrl();
    // https://google.com/search?q=simpsons

Raw parameters

By default parameters are encoded for urls. For instance "Homer Simpsons" will become "Homer+Simpsons" but "Homer+Simpsons" will become "Homer%2BSimpson"

    use Serps\SearchEngine\Google\GoogleUrl;

    $googleUrl = new GoogleUrl();
    $googleUrl->setParam('q', 'Homer+Simpson');
    echo $googleUrl->buildUrl();
    // https://google.com/search?q=Homer%2BSimpson

It's possible to deal with raw params, this way the param will be passed to the url with no additional encoding. That is achieved by passing true as the third argument of setParam.

    $googleUrl = new GoogleUrl();
    $googleUrl->setParam('q', 'Homer+Simpson', true);
    echo $googleUrl->buildUrl();
    // https://google.com/search?q=Homer+Simpson

More parameters

Some parameters are very common and for some of them we created convenient shortcuts. See the list:

setSearchTerm

$url->setSearchTerm($searchTerm)

Sets the keywords to search for. Modifies the value for the q parameter.

setPage

$url->setPage($pageNumber)

Sets the page to parse (starts at 1). Modifies the value for the start parameter.

setResultsPerPage

$url->setResultsPerPage($resultsPerPages)

Sets the number of results per pages (between 1 and 100). Modifies the value for the num parameter.

setLanguageRestriction

$url->setLanguageRestriction($lang)

Sets language of the results. Modifies the value for the lr parameter. e.g "lang_en".

setAutoCorrectionEnabled

$url->setAutoCorrectionEnabled($enabled)

Sets if the auto correction should be enabled (true or false). Modifies the value for the nfpr parameter.
