Conditional Statements

• @if directive is used for conditional statements, e.g., @if ($grade==75)

• @else is used for the default condition, e.g., @else You Failed!
• @endif is used to end the conditional statement

Switch Case

• @switch directive is used for switch case statements, e.g., @switch ($grade)
• @case is used to specify a case, e.g., @case(80)
• @break is used to break out of the switch case
• @default is used for the default case, e.g., @default Your grade is not known!
• @endswitch is used to end the switch case statement

Loops

• @for directive is used for for loops, e.g., @for ($i = 0; $i < 10)
• @endfor is used to end the for loop
• @foreach directive is used for foreach loops, e.g., @foreach ($students as $student)
• @endforeach is used to end the foreach loop

Loop Variables

• $loop variable provides information about the current loop iteration
• $loop->index returns the index of the current loop iteration (starts at 0)
• $loop->iteration returns the current loop iteration (starts at 1)
• $loop->remaining returns the iteration remaining in the loop
• $loop->count returns the total number of items in the array being iterated
• $loop->first returns whether this is the first iteration through the loop
• $loop->last returns whether this is the last iteration through the loop
• $loop->depth returns the nesting level of the current loop
• $loop->parent returns the parent's loop variable when in a nested loop

Check if Set and Check if Empty

• @isset directive is used to check if a variable is set, e.g., @isset ($students)
• @endisset is used to end the isset statement
• @empty directive is used to check if a variable is empty, e.g., @empty ($students)
• @endempty is used to end the empty statement
