IcuVersion::compare()

static bool compare(string $version1, string $version2, string $operator, int|null $precision = null)

Compares two ICU versions with an operator.

This method is identical to {@link version_compare()}, except that you can pass the number of regarded version components in the last argument $precision.

Also, a single digit release version and a single digit major version are contracted to a two digit release version. If no major version is given, it is substituted by zero.

Examples:

IcuVersion::compare('1.2.3', '1.2.4', '==')
// => false

IcuVersion::compare('1.2.3', '1.2.4', '==', 2)
// => true

IcuVersion::compare('1.2.3', '12.3', '==')
// => true

IcuVersion::compare('1', '10', '==')
// => true

Parameters

string	$version1	A version string
string	$version2	A version string to compare
string	$operator	The comparison operator
int\|null	$precision	The number of components to compare. Pass NULL to compare the versions unchanged.

Return Value

bool	Whether the comparison succeeded
