With its seemingly magical powers, for loops can help you avoid the dreaded copy-paste monotony, transforming your code into a sleek, efficient machine. But fear not, brave coder! Your trusty sidekick, the "for loop," is here to save the day.

Comparing For Loops With Other Loop Types In PHP.Common Mistakes And Pitfalls In PHP For Loops.Tips for Streamlining Your PHP For Loops.Side note: In Perl you can simply assign an array or list to a hash and this is done automatically - with a warning if there's an odd number of elements in the list/array. PowerShell uses what is called "banker's rounding" and rounds N.5 numbers to the closest even integer, so 1.5 is rounded to 2 and 2.5 is also rounded to 2. If you specify a decimal number, it will be cast to the type. " (two periods) enumerates ranges of integers between the start and end integer specified. A binary operator means it has an argument on both its left and right side, while a unary operator usually only has something on its right-hand side, and always only one argument in that latter unary case. "%" is only the modulus operator when it's used as a binary operator. I should mention that if PowerShell sees a "%" in the middle of a pipeline, it will interpret it as the ForEach-Object cmdlet. Zero is considered false - unless it's a string ("0" or '0' or any other crazy unicode quote character - wow, terrible decision.). The modulus operator (%) returns zero when there is no remainder and the number is evenly divisible. The loop below gets all numbers between 1 and 50 that are evenly divisible by 10, using the modulus operator. On, I added some notes about LINQ foreach.

This article was written about PowerShell version 2, which is the default in Windows 2008 R2 and Windows 7. I talk more extensively about this below.įor an article about the "regular" PowerShell for loop, click here. A cmdlet is a type of command.Īs for the alias "%", this also doubles as the modulus operator, if used as a binary operator - one that takes an argument on both sides. The logic behind that is as follows: If the word foreach is used at the beginning of a statement (or after a label), it's considered the foreach loop keyword, while if it's anywhere else, it'll be recognized as the ForEach-Object cmdlet/command. These objects are found in the special variable " $_" inside the (process) script block you pass to ForEach-Object.Ī bit confusingly (but conveniently), you can use both the shorthand (aliases) "%" and "foreach" instead of ForEach-Object in a pipeline.

The cmdlet ForEach-Object is used for processing objects coming in via the pipeline. In PowerShell there's a keyword called foreach that's used for looping over collections such as arrays (technically pipelines).
