help on PHP arrays

[dg]

hi all ,

  need to know whether an array with too many indexes  or  only one index creates difference in processing time?

for example say array $aTotalsMarks

 

        $aTotalsMarks[$sSchool][$sDivision][$iRollNumber][$sExamCode][$sSubject];

And

        $aTotalsMarks[$sSchool.'##'.$sDivision.'##'.$iRollNumber.'##'.$sExamCode.'##'.$sSubject];

 

Does  the above two arrays make a difference in processing if the number of indexes are increased or decreased ?

 

thanx.....

dunno w/c is best to use

but i prefer using ....

$aTotalsMarks[$sSchool][$sDivision][$iRollNumber][$sExamCode][$sSubject];

As with any other performance related issue in PHP I think the answer is: As long as you do not do this 50000 times in one script I don't think you'll see a difference.

 

Get the execution time of your script with both methods and decide which to use (+ report back the result ):

i agree with wuhtzu........

you used the 1 u r more convenient with......dat is if the the two arrays have a very slight difference...
