Query modifiers

Here’s the documentation for the included URI modifiers which are modifying the URI query component.

Sorting the query keys¶

Description

<?php

public KsortQuery::__construct(mixed $sort = SORT_REGULAR)
copy 📋

Sorts the query according to its key values.

Parameters

The $sort argument can be:

one of PHP’s sorting constant used by the ksort function

<?php

use League\Uri\Schemes\Http;
use League\Uri\Modifiers\KsortQuery;

$uri = Http::createFromString("http://example.com/test.php?kingkong=toto&foo=bar+baz#doc3");
$modifier = new KsortQuery(SORT_REGULAR);
$newUri = $modifier->__invoke($uri);
echo $newUri; //display "http://example.com/test.php?foo=bar%20baz&kingkong=toto#doc3"
copy 📋

a user defined comparison function used by the uksort function

<?php

use League\Uri\Schemes\Http;
use League\Uri\Modifiers\KsortQuery;

$sort = function ($value1, $value2) {
    return strcasecmp($value1, $value2);
};

$modifier = new KsortQuery($sort);

$uri = Http::createFromString("http://example.com/test.php?kingkong=toto&foo=bar+baz#doc3");
$newUri = $modifier->__invoke($uri);
echo $newUri; //display "http://example.com/test.php?foo=bar%20baz&kingkong=toto#doc3"
copy 📋

Methods

The withAlgorithm method is deprecated since version 4.1 and will be removed in the next major release

The sorting algorithm can be change at any given time. By default if none is provided. The sorting is done using PHP’s ksort sort flag parameters. But you can also provide a callable as sorting mechanism using the withAlgorithm method.

<?php

use League\Uri\Schemes\Http;
use League\Uri\Modifiers\KsortQuery;

$uri = Http::createFromString("http://example.com/test.php?kingkong=toto&foo=bar+baz#doc3");
$modifier = new KsortQuery();
$newUri = $modifier->__invoke($uri);
echo $newUri; //display "http://example.com/test.php?foo=bar%20baz&kingkong=toto#doc3"
$altModifier = $modifier->withAlgorithm(function ($value1, $value2) {
    return strcasecmp($value1, $value2);
});
$altUri = $altModifier->__invoke($uri);
echo $altUri; //display "http://example.com/test.php?foo=bar%20baz&kingkong=toto#doc3"
copy 📋

Merging query string¶

Description

<?php

public MergeQuery::__construct(string $query)
copy 📋

Merges a submitted query string to the URI object to be modified

Example

<?php

use League\Uri\Schemes\Http;
use League\Uri\Modifiers\MergeQuery;

$uri = Http::createFromString("http://example.com/test.php?kingkong=toto&foo=bar+baz#doc3");
$modifier = new MergeQuery('kingkong=godzilla&toto');
$newUri = $modifier->__invoke($uri);
echo $newUri; //display "http://example.com/test.php?kingkong=godzilla&foo=bar%20baz&&toto#doc3"
copy 📋

Methods

The withQuery method is deprecated since version 4.1 and will be removed in the next major release

At any given time you can create a new modifier with another query string to merge using the withQuery method.

<?php

use League\Uri\Schemes\Http;
use League\Uri\Modifiers\MergeQuery;

$uri = Http::createFromString("http://example.com/test.php?kingkong=toto&foo=bar+baz#doc3");
$modifier = new MergeQuery('kingkong=godzilla&toto');
$newUri = $modifier->__invoke($uri);
echo $newUri; //display "http://example.com/test.php?kingkong=godzilla&foo=bar%20baz&&toto#doc3"
$altModifier = $modifier->withQuery('foo=1');
$altUri = $altModifier->__invoke($uri);
echo $altUri; //display "http://example.com/test.php?kingkong=toto&foo=1#doc3"
copy 📋

Removing query keys¶

Description

<?php

public RemoveQueryKeys::__construct(array $keys = [])
copy 📋

Removes query keys from the current URI path.

Examples

<?php

use League\Uri\Schemes\Http;
use League\Uri\Modifiers\RemoveQueryKeys;

$uri = Http::createFromString("http://example.com/test.php?kingkong=toto&foo=bar+baz#doc3");
$modifier = new RemoveQueryKeys(["foo"]);
$newUri = $modifier->__invoke($uri);
echo $newUri; //display "http://example.com/test.php?kingkong=toto#doc3"
copy 📋

Methods

The withKeys method is deprecated since version 4.1 and will be removed in the next major release

You can update the keys chosen by using the withKeys method

<?php

use League\Uri\Schemes\Http;
use League\Uri\Modifiers\RemoveQueryKeys;

$uri = Http::createFromString("http://example.com/test.php?kingkong=toto&foo=bar+baz#doc3");
$modifier = new RemoveQueryKeys(["foo"]);
$newUri = $modifier->__invoke($uri);
echo $newUri; //display "http://example.com/test.php?kingkong=toto#doc3"
$altModifier = $modifier->withKeys(["kingkong"]);
$altUri = $altModifier->__invoke($uri);
echo $altUri; //display "http://example.com/test.php?foo=bar%20baz#doc3"
copy 📋

Filtering query key/values¶

Description

<?php

public FilterQuery::__construct(callable $callable, int $flag = 0)
copy 📋

Parameters

The $callable argument is a callable used by PHP’s array_filter
The $flag argument is a int used by PHP’s array_filter

For Backward compatibility with PHP5.5 which lacks these flags constant you can use the library constants instead:

League\Uri\Interfaces\Collection constants	PHP's 5.6+ constants
`Collection::FILTER_USE_KEY`	`ARRAY_FILTER_USE_KEY`
`Collection::FILTER_USE_BOTH`	`ARRAY_FILTER_USE_BOTH`
`Collection::FILTER_USE_VALUE`	`0`

Examples

Filter selected query keys and/or values from the current URI path to keep.

<?php

use League\Uri\Schemes\Http;
use League\Uri\Modifiers\FilterQuery;
use League\Uri\Interfaces\Collection;

$filter = function ($value) {
    return strpos($value, 'f');
};
$uriString = "http://example.com/test.php?kingkong=toto&foo=bar+baz#doc3";
$uri = Http::createFromString($uriString);
$modifier = new FilterQuery($filter, Collection::FILTER_USE_KEY);
echo $newUri; //display "http://example.com/test.php?foo=bar%20baz#doc3"
copy 📋

Methods

The withCallable and withFlag methods are deprecated since version 4.1 and will be removed in the next major release

You can update the URI modifier using:

withCallable method to alter the filtering function;
withFlag method to alter the filtering flag;

<?php

use League\Uri\Schemes\Http;
use League\Uri\Modifiers\FilterQuery;
use League\Uri\Interfaces\Collection;

$uri = Http::createFromString("http://example.com/test.php?kingkong=toto&foo=bar+baz#doc3");
$modifier = new FilterQuery(function ($value) {
    return strpos($value, 'f');
}, Collection::FILTER_USE_KEY);
echo $newUri; //display "http://example.com/test.php?foo=bar%20baz#doc3"
$altModifier = $modifier->withCallable(function ($value) {
    return false !== strpos($value, 'o');
})->withFlag(Collection::FILTER_USE_VALUE');
$altUri = $altModifier->__invoke($uri);
echo $altUri; //display "http://example.com/test.php?kingkong=toto#doc3"
copy 📋
