//This is are two little functions that I made to quickly debug my arrays
//while making php scripts.  You can pass these things any variable (both
//arrays and non arrays), and it will print out everything that is in it.
//It will even print out embedded arrays, so if you have arrays in arrays
//in arrays, it will print all that out in a consice enough format that you
//will know exactly what is in that variable.
//
//You should get output with "key => val", which should look something like
//the following:
//
// admin =>
//         user           => 1
//         screwball      => 2
//         admin          => 4
//         . . .
// is    =>
//         student worker => 1
//         hacker         => 2
//         nerd           => 4
//         admin          => 8
// . . .
//
//call it like the following (where $testVar is a variable of you choice)
//
//  print_array($testVar);
//
//if your array contains any html code, you may want to call it instead as:
//
//  print_array($testVar,"<xmp>","</xmp>");
//
//Should be very easy to throw in your code and use...hope you find it useful

人生到处知何似？
    应似飞鸿踏雪泥。
        泥上偶然留指爪，
            鸿飞那复计东西！
