The while<\/code> loop in PHP is a fundamental control structure that repeatedly executes a block of code as long as the specified condition evaluates to true<\/code>. It is especially useful when you do not know beforehand how many iterations are needed.<\/p>\n\n\n\n

Example: Counting Motorcycles<\/h2>\n\n\n\n

Here\u2019s an example where we display the number of motorcycles a showroom can store, as long as the count remains under 6:<\/p>\n\n\n\n

$motorcycleCount = 1;\n\nwhile ($motorcycleCount < 6) {\n  echo $motorcycleCount;\n  $motorcycleCount++;\n}<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Note:<\/em> It is essential to increment the variable within the loop to avoid an infinite loop.<\/p>\n\n\n\n
The break Statement<\/h2>\n\n\n\n
The break<\/code> keyword is used to terminate a loop prematurely, even if the condition remains true<\/code>.<\/p>\n\n\n\n
Example: Break at a Specific Car Count<\/h2>\n\n\n\n
Stop counting the cars in the showroom when the count reaches 3:<\/p>\n\n\n\n
$carCount = 1;\n\nwhile ($carCount < 6) {\n  if ($carCount == 3) break;\n  echo $carCount;\n  $carCount++;\n}<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
The continue Statement<\/h2>\n\n\n\n
The continue<\/code> keyword skips the current iteration and moves on to the next.<\/p>\n\n\n\n
Example: Skipping Specific Motorcycles<\/h2>\n\n\n\n
Skip displaying a motorcycle’s brand if it\u2019s the third one:<\/p>\n\n\n\n
$motorcycleIndex = 0;\n\nwhile ($motorcycleIndex < 6) {\n  $motorcycleIndex++;\n  if ($motorcycleIndex == 3) continue;\n  echo $motorcycleIndex;\n}<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Alternative Syntax<\/h2>\n\n\n\n
PHP provides an alternative syntax for the while<\/code> loop using endwhile<\/code>. This can make your code more readable in some cases.<\/p>\n\n\n\n
Example: Counting Cars<\/h2>\n\n\n\n
$carCount = 1;\n\nwhile ($carCount < 6):\n  echo $carCount;\n  $carCount++;\nendwhile;<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Increment by Steps<\/h2>\n\n\n\n
You can adjust the increment step to control how the loop progresses.<\/p>\n\n\n\n
Example: Counting Cars by Tens<\/h2>\n\n\n\n
Let\u2019s count cars in a parking lot, increasing the count by 10 each time, until we reach 100:<\/p>\n\n\n\n
$carCount = 0;\n\nwhile ($carCount < 100) {\n  $carCount += 10;\n  echo $carCount . "<br>";\n}<\/pre><\/div>\n","protected":false},"excerpt":{"rendered":"
