static void setPlaceholder(string $placeholder, array $values)

Register possible (dummy) values for a dynamic placeholder value.

Matching configuration values will be processed with a provided value, one by one. After a provided value is successfully processed the configuration value is returned as is, thus preserving the placeholder.

Parameters

string $placeholder

Return Value

void

static void setPlaceholderUniquePrefix(string $prefix)

Sets a common prefix for dynamic placeholder values.

Matching configuration values will be skipped from being processed and are returned as is, thus preserving the placeholder. An exact match provided by {see setPlaceholder()} might take precedence.

Parameters

string $prefix

Return Value

void

static void resetPlaceholders()

Resets all current placeholders available.
