By "line" you mean the AC line. by "phase" you mean 1 phase of a multi-phase line.

Line voltage is the voltage seen on the AC line, typically single phase. Line current is the current that results when that voltage is applied to a load.

If you have a 3 phase line, then each of the 3 phases (a separate wire) has it's own voltage, phase voltage. Again, if you apply a load to that phase, then phase current results.

Electrical power is distributed through the network where all the transformer/ switchgears have three phases(commonly) .These three phases are connected in star or delta. The current flowing in the line ( outside the transformer) is called line current whereas current flowing in one of the windings of the transformer or generator is called phase current.
in delta connected I(line)=1.732 XI(phase)
in Y connected I (line)= I (phase)
