Php server integer, floating point, data I/O capability test function-PHP source code

The following provides three functions to test the server's integer computing capability test, floating point computing capability test, and data IO capability test. // The following provides three functions to test the server's integer computing capability test, floating point computing capability test, and data IO capability test.

Script ec (2); script

The Code is as follows:
Function test_int () { $ TimeStart = gettimeofday (); For ($ I = 0; I I <3000000; $ I ++ ); { $ T = 1 + 1; } $ TimeEnd = gettimeofday (); $ Time = ($ timeEnd ["usec"]-$ timeStart ["usec"])/1000000 + $ timeEnd ["sec"]-$ timeStart ["sec"]; $ Time = round ($ time, 3). "seconds "; Return $ time; }

/*--------
Floating Point computing capability test
----------*/

The Code is as follows:
Function test_float () { $ T = pi (); $ TimeStart = gettimeofday (); For ($ I = 0; I I <3000000; $ I ++ ); { Sqrt ($ t ); } $ TimeEnd = gettimeofday (); $ Time = ($ timeEnd ["usec"]-$ timeStart ["usec"])/1000000 + $ timeEnd ["sec"]-$ timeStart ["sec"]; $ Time = round ($ time, 3). "seconds "; Return $ time; }

/*-----
Test data IO capability
-----*/

The Code is as follows:
Function test_io () { $ Fp = fopen (PHPSELF, "r "); $ TimeStart = gettimeofday (); For ($ I = 0; I I <10000; $ I ++) { Fread ($ fp, 10240 ); Rewind ($ fp ); } $ TimeEnd = gettimeofday (); Fclose ($ fp ); $ Time = ($ timeEnd ["usec"]-$ timeStart ["usec"])/1000000 + $ timeEnd ["sec"]-$ timeStart ["sec"]; $ Time = round ($ time, 3). "seconds "; Return ($ time ); }

Many companies write related server probe testing tools. We only provide three simple integer operations, floating point operations, and I/O data output stress tests.
