The for statement is used when you know how many times you want to execute a statement or a block of statements.
We will discuss about continue and break keywords used to control the loops execution. The loop.length, loop.revindex, loop.revindex0, and loop.last variables are only available for PHP arrays, or objects that implement the Countable.
You can specify how many times the execution will.
FOR LOOP IN PHP CODE
Now, PHP for loop is meant to execute portions of code multiple times. Using foreach PHP code blocks will be run repeatedly with their every element in a row. They are meant to be used with the more complex types of PHP variables - arrays and objects. These for loops are also featured in the C++, Java, PHP, and Perl languages. PHP foreach loops have a particular purpose. While − loops through a block of code if and as long as a specified condition is true.ĭo.while − loops through a block of code once, and then repeats the loop as long as a special condition is true.įoreach − loops through a block of code for each element in an array. Three-expression for loops are popular because the expressions specified for the three parts can be nearly anything, so this has quite a bit more flexibility than the simpler numeric range form shown above. PHP supports following four loop types.įor − loops through a block of code a specified number of times.
All PHP exercises are available in the form of PHP problem, description and solution. The For statement takes three expressions inside its parentheses, separated by semicolons. These PHP Loop exercises contain programs on PHP for Loop, while Loop, mathematical series, and various string pattern designs. Loops in PHP are used to execute the same block of code a specified number of times. The for loop is the most difficult loop in PHP. If multiple loops are nested, the break statement accepts a numerical value to indicate how many loops to break out of.
