Do while syntax php
Important notes. Condition statement is however only one condition statement. Condition statement for loop will be an infinite if it is blank. Condition expression whiledowhile loop will be an infinite if it is a always TRUE. Loop statement(s) these statements are tasks in each steps. Counter variables are often used in the steps.The while loop in PHP has two components, one is a condition and other is the code to be executed. It executes the given code until the specified condition is true. do while syntax php
The meaning of a while statement is simple. It tells PHP to execute the nested statement(s) repeatedly, as long as the while expression evaluates to TRUE. The value of the expression is checked each time at the beginning of the loop, so even if this value changes during the execution of the nested statement(s), execution will not stop until the end of the iteration (each time PHP runs the statements in the loop is
PHP supports following four loop types. for loops through a block of code a specified number of times. while loops through a block of code if and as long as a specified condition is true. dowhile loops through a block of code once, and then repeats the loop as long as a special condition is true. dowhile (PHP 4, PHP 5, PHP 7) dowhile loops are very similar to while loops, except the truth expression is checked at the end of each iteration instead of in the beginning. do while syntax php The PHP dowhile loop statement allows you to execute a block of code repeatedly based on a condition. Unlike the while loop statement whose the condition is checked at the beginning of each iteration, the condition in the PHP dowhile statementis checked at the end of each iteration.
PHP dowhile Loop The dowhile loop is a variant of while loop, which evaluates the condition at the end of each loop iteration. With a dowhile loop the block of code executed once, and then the condition is evaluated, if the condition is true, the statement is repeated as long as do while syntax php Sep 11, 2019 PHP Loop: For, ForEach, While, Do While [Example A Loop is an Iterative Control Structure that involves executing the same number of code a number of times until a certain condition is met. If the conditional statement is false then the code within the loop is not executed. On the other hand, a dowhile loop always executes its block of code at least once. This is because the conditional statement is not checked until after the contained code has been executed. PHP php dowhile loop PHP dowhile loop In dowhile loop always execute block of code at least once, then check condition and repeat the loop as long as the condition is true. The PHP dowhile loop is guaranteed to run at least once. It executes the code at least one time always because condition is checked after executing the code. SyntaxRating: 4.99 / Views: 804
