Methods
- compare() : bool
- Compares two ICU versions with an operator.
- normalize() : string|null
- Normalizes a version string to the number of components given in the parameter $precision.
- __construct() : mixed
- Must not be instantiated.
Methods
compare()
Compares two ICU versions with an operator.
public
static compare(string $version1, string $version2, string $operator[, int|null $precision = null ]) : bool
This method is identical to , 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
- $version1 : string
- $version2 : string
- $operator : string
- $precision : int|null = null
-
The number of components to compare. Pass NULL to compare the versions unchanged.

boolnormalize()
Normalizes a version string to the number of components given in the parameter $precision.
public
static normalize(string $version, int|null $precision) : string|null
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'
Parameters
- $version : string
- $precision : int|null
-
The number of components to include. Pass NULL to return the version unchanged.
