This is useful if you would like to write programs working only on some versions of PHP. version_compare() returns -1 if the first version is lower than the second, 0 if they are equal, and +1 if the second is lower. If you specify the third optional operator argument, you can test for a particular relationship. The possible operators are: <, lt, <=, le, >, gt, >=, ge, ==, =, eq, !=, <>, ne respectively. Using this argument, the function will return 1 if the realtionship is the one specified by the operator, 0 otherwise.
