public __construct ( string $cfgName, boolean | callback $evaluation, boolean $approveCfgAbsence = false, string | null $testMessage = null, string | null $helpHtml = null, string | null $helpText = null, boolean $optional = false ) |
|
$cfgName |
string |
The configuration name used for ini_get() |
|
$evaluation |
boolean | callback |
Either a Boolean indicating whether the configuration should evaluate to true or false,
or a callback function receiving the configuration value as parameter to determine the fulfillment of the requirement |
|
$approveCfgAbsence |
boolean |
If true the Requirement will be fulfilled even if the configuration option does not exist, i.e. ini_get() returns false.
This is helpful for abandoned configs in later PHP versions or configs of an optional extension, like Suhosin.
Example: You require a config to be true but PHP later removes this config and defaults it to true internally. |
|
$testMessage |
string | null |
The message for testing the requirement (when null and $evaluation is a Boolean a default message is derived) |
|
$helpHtml |
string | null |
The help text formatted in HTML for resolving the problem (when null and $evaluation is a Boolean a default help is derived) |
|
$helpText |
string | null |
The help text (when null, it will be inferred from $helpHtml, i.e. stripped from HTML tags) |
|
$optional |
boolean |
Whether this is only an optional recommendation not a mandatory requirement |
