class IcuVersion
Facilitates the comparison of ICU version strings.
static bool | compare(string $version1, string $version2, string $operator, int|null $precision = null) Compares two ICU versions with an operator. | |
static string|null | normalize(string $version, int|null $precision) Normalizes a version string to the number of components given in the parameter $precision. |
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
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. |
bool | Whether the comparison succeeded |
normalize() |
Normalizes a version string to the number of components given in the parameter $precision.
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::normalize('1.2.3.4');
// => '12.3.4'
IcuVersion::normalize('1.2.3.4', 1);
// => '12'
IcuVersion::normalize('1.2.3.4', 2);
// => '12.3'
string | $version | An ICU version string |
int|null | $precision | The number of components to include. Pass NULL to return the version unchanged. |
string|null | the normalized ICU version or NULL if it couldn't be normalized |
