Print("this is not printed because for loop is terminated because of break but not due to fail in condition") Here are a few examples: # Prints out 0,1,2,3,4 and then it prints "count value reached 5" Note that the "else" part is executed even if there is a continue statement. If a break statement is executed inside the for loop then the "else" part is skipped. When the loop condition of "for" or "while" statement fails then code part in "else" is executed. # Prints out only odd numbers - 1,3,5,7,9 While loops repeat as long as a certain boolean condition is met. Note that the range function is zero based. (Python 3 uses the range function, which acts like xrange). The difference between range and xrange is that the range function returns a new list with numbers of that specified range, whereas xrange returns an iterator, which is more efficient. Here is an example: primes = įor loops can iterate over a sequence of numbers using the "range" and "xrange" functions. The "for" loopįor loops iterate over a given sequence. This closure should type-hint the type of object that it is responsible for rendering.There are two types of loops in Python, for and while. To accomplish this, you should invoke Blade's stringable method. In these cases, Blade allows you to register a custom echo handler for that particular type of object. However, sometimes you may not have control over the _toString method of a given class, such as when the class that you are interacting with belongs to a third-party library. The _toString method is one of PHP's built-in "magic methods". If you attempt to "echo" an object using Blade, the object's _toString method will be invoked. The cached Blade views may be removed using the view:clear Artisan command. If the array element has a numeric key, it will always be included in the rendered class list:Īfter updating the logic of a Blade directive, you will need to delete all of the cached Blade views. The directive accepts an array of classes where the array key contains the class or classes you wish to add, while the value is a boolean expression. The directive conditionally compiles a CSS class string. When in a nested loop, the parent's loop variable. Whether this is an odd iteration through the loop. Whether this is an even iteration through the loop. Whether this is the last iteration through the loop. Whether this is the first iteration through the loop. The total number of items in the array being iterated. The current loop iteration (starts at 1). The index of the current loop iteration (starts at 0). Of course, as mentioned in the documentation on views, data may be passed to the Blade view using the view helper's second $loop variable also contains a variety of other useful properties: Property blade.php file extension and are typically stored in the resources/views directory.īlade views may be returned from routes or controllers using the global view helper. In fact, all Blade templates are compiled into plain PHP code and cached until they are modified, meaning Blade adds essentially zero overhead to your application. Unlike some PHP templating engines, Blade does not restrict you from using plain PHP code in your templates. Blade is the simple, yet powerful templating engine that is included with Laravel.
