html_build_attributes

(PHP 5 >= 5.4, PHP 7, PHP 8)
html_build_attributes — Generate a string of HTML attributes.

Description

string html_build_attributes( array $attr [, callable $callback = null ] )

Generate a string of HTML attributes from the associative array provided.

Parameters

• attr — Associative array, or object containing properties, representing attribute names and values.

  If attr is a non-iterable object, then only accessible non-static properties will be incorporated into the result.

  If an attribute name is an empty string, the attribute is ignored. The attribute name will be trimmed of leading/trailing whitespace.

  If an attribute value is callable (either as a Closure or invokable), it is called and the returned value continues processing.

  If an attribute value is null, the attribute is ignored.

  If an attribute value is an arrayable or a stringable object, it is converted to its primitive type.

  If an attribute value is a boolean and true, the attribute will be rendered without a value, otherwise the attribute is ignored.

  If an attribute value is an array, only numbers and strings are accepted. Strings of the array will be trimmed of leading/trailing whitespace. If the filtered array is empty, the attribute is ignored.

  Any other value will be serialized using json_encode().

• callback — Callback function for escaping the values for the HTML attributes.

  If no sanitizer is provided, htmlspecialchars() is used;

  If using WordPress, the esc_attr() function is used.

Return Values

Returns a string of HTML attributes or a empty string if attr is invalid or empty.
