Methods
__construct()
AssetsOptimization constructor.
public
__construct() : mixed
Return values
mixed —buffer_end()
Processes/optimizes the output-buffered content and returns it.
public
buffer_end(string $html) : string
If the content is not processable, it is returned unmodified.
Parameters
- $html : string
-
Buffered content.
Return values
string —buffer_start()
Setup output buffering if needed.
public
buffer_start() : void
Return values
void —filter_css()
public
filter_css(mixed $html) : mixed
Parameters
- $html : mixed
Return values
mixed —filter_test()
public
filter_test(mixed $html) : mixed
Parameters
- $html : mixed
Return values
mixed —getInstance()
public
static getInstance() : AssetsOptimization
Return values
AssetsOptimization —is_valid_buffer()
Returns true if given markup is considered valid/processable/optimizable.
public
is_valid_buffer(string $content) : bool
Parameters
- $content : string
-
Markup.
Return values
bool —load_assets_on_demand()
public
load_assets_on_demand() : mixed
Return values
mixed —mbstring_available()
Returns true when mbstring is available.
public
mbstring_available() : bool
Return values
bool —move_css_to_head()
public
move_css_to_head() : mixed
Return values
mixed —should_buffer()
Returns true if all the conditions to start output buffering are satisfied.
public
should_buffer() : bool
Return values
bool —strlen()
Attempts to return the number of characters in the given $string if mbstring is available. Returns the number of bytes (instead of characters) as fallback.
public
strlen(string $string[, string|null $encoding = null ]) : int
Parameters
- $string : string
-
String.
- $encoding : string|null = null
-
Encoding.
Return values
int —Number of characters or bytes in given $string (characters if/when supported, bytes otherwise).
strpos()
Multibyte-capable strpos() if support is available on the server.
public
strpos(string $haystack, string $needle, int $offset[, string|null $encoding = null ]) : int|false
If not, it falls back to using \strpos().
Parameters
- $haystack : string
-
Haystack.
- $needle : string
-
Needle.
- $offset : int
-
Offset.
- $encoding : string|null = null
-
Encoding. Default null.
Return values
int|false —substr_replace()
Our wrapper around implementations of \substr_replace() that attempts to not break things horribly if at all possible.
public
substr_replace(string $string, string $replacement, int $start[, int|null $length = null ][, string|null $encoding = null ]) : string
Uses mbstring if available, before falling back to regular substr_replace() (which works just fine in the majority of cases).
Parameters
- $string : string
-
String.
- $replacement : string
-
Replacement.
- $start : int
-
Start offset.
- $length : int|null = null
-
Length.
- $encoding : string|null = null
-
Encoding.
Return values
string —inject_in_html()
Injects/replaces the given payload markup into `$html` at the specified location.
protected
inject_in_html(string $payload, array<string|int, mixed> $where, mixed $html) : void
If the specified tag cannot be found, the payload is appended into $html along with a warning wrapped inside tags.
Parameters
- $payload : string
-
Markup to inject.
- $where : array<string|int, mixed>
-
Array specifying the tag name and method of injection. Index 0 is the tag name (i.e.,
</body>). Index 1 specifies ?'before', 'after' or 'replace'. Defaults to 'before'. - $html : mixed
