Array inside an array
hi All,
I have a array as follows,
array1=("xx" "abc" "def" "xyz")
and each array1[index] is also storing some array values, like
array1[1]=abc
and abc=("a" "b" "c") etcetera etcetra.........
Note : each subarray under array1 have index 3 i.e. it can max contain 3 values
if i echo ${abc[index]} [ where index is 1,2,3...] it works fine.
but if i loop thru it's not printing the values, can anybody help me solving this thru loop,
my loop goes like this
cnt=1
total_Array=${#array1[*]}
no_loop_thru=${#abc[*]}
while [ $cnt -lt $total_Array ]
do
srch_fld=`echo ${array1[$cnt]}`
j=1
while [ $j -le $no_loop_thru ]
do
#var1=`$srch_fld[$j]`
#echo ${var1}
echo ${srch_fld[$j]}
j=`expr $j + 1`
done
cnt=`expr $cnt + 1`
done
can anybody suggest any improvement on this......LOOP

SYNOPSIS
array array_intersect (array $array1, array $array2, [array $...])
DESCRIPTION
array_intersect(3) returns an array containing all the values of $array1 that are present in all the arguments. Note that keys are pre-
served.
PARAMETERS
o $array1
- The array with master values to check.
o $array2
- An array to compare values against.
o $...
- A variable list of arrays to compare.
RETURN VALUES
Returns an array containing all of the values in $array1 whose values exist in all of the parameters.
EXAMPLES
Example #1
array_intersect(3) example
<?php
$array1 = array("a" => "green", "red", "blue");
$array2 = array("b" => "green", "yellow", "red");
