Function Documentation

_parse_fallback()

Sabre\Uri\_parse_fallback

(

$uri

)

This function is another implementation of parse_url, except this one is fully written in PHP.

The reason is that the PHP bug team is not willing to admit that there are bugs in the parse_url implementation.

This function is only called if the main parse method fails. It's pretty crude and probably slow, so the original parse_url is usually preferred.

Parameters

string

$uri

Returns

array

normalize()

Sabre\Uri\normalize

(

$uri

)

Takes a URI or partial URI as its argument, and normalizes it.

After normalizing a URI, you can safely compare it to other URIs. This function will for instance convert a %7E into a tilde, according to rfc3986.

It will also change a %3a into a %3A.

Parameters

string

$uri

Returns

string

parse()

Sabre\Uri\parse

(

$uri

)

Parses a URI and returns its individual components.

This method largely behaves the same as PHP's parse_url, except that it will return an array with all the array keys, including the ones that are not set by parse_url, which makes it a bit easier to work with.

Unlike PHP's parse_url, it will also convert any non-ascii characters to percent-encoded strings. PHP's parse_url corrupts these characters on OS X.

Parameters

string

$uri

Returns

array

split()

Sabre\Uri\split

(

$path

)

Returns the 'dirname' and 'basename' for a path.

The reason there is a custom function for this purpose, is because basename() is locale aware (behaviour changes if C locale or a UTF-8 locale is used) and we need a method that just operates on UTF-8 characters.

In addition basename and dirname are platform aware, and will treat backslash () as a directory separator on windows.

This method returns the 2 components as an array.

If there is no dirname, it will return an empty string. Any / appearing at the end of the string is stripped off.

Parameters

string

$path

Returns

array
