This type of for loop is arguably the most generalized.
The Perl last operator works just like the break operator in other languages, breaking out of the loop when the last operator is encountered. Each time through the loop, the variable i takes on the value of the next object inIn a related note, you can break out of a Perl for loop using the Perl last operator, like this: if (SOME_TEST_CONDITION) How do i get the next element of the array and loop it again when it comes to the last element Problem: Unable to apply the array to the url and let it goes to the next item in the array based on the Item Code.

Related - how to break out of a Perl for loop The while loop executes a block of code as long as the specified condition is true. Make sure your rewind() implementation tries to grab the first result so that the subsequent call to valid() will know whether or not the result set is empty. In the code just before this for loop I had just read all the records of a Perl script into an array named and in the Perl for loop shown below I'm skipping over all the strings I'm not really interested in: for skip blank linesĪs you can see, you use the Perl next operator to skip to the next element in a Perl for loop, and there are at least two ways to use the next operator, as shown in the examples above: inside an if statement, or before an if statement. Otherwise your code will break if the same iterator is used in two consecutive foreach loops when the first loop terminates with a break statement before all the results are iterated over. You can see some decent examples of the Perl next operator in the following code. When you're in a Perl for loop (iterating over an array or hash), and you want to move on to the next element in your array or hash, just use the Perl next operator, like this: for (SOME_TEST_CONDITION) Problem: You're writing code for a Perl loop, and you need to write some logic to skip over the current element in the loop, and move on to the next loop element. How to fix it EDIT: based on the answers I will move the echo 'Total' stuff at the beginning of the next iteration instead of at the bottom of the current iteration.
