The PHP for Loop. The for loop is used when you know how many times the script should run. Syntax for (expression1, expression2, expression3) { // code block} This is how it works: expression1 is evaluated once; expression2 is evaluated before each iteration; expression3 is evaluated after each iteration

for loops are the most complex loops in PHP. They behave like their C counterparts. The syntax of a for loop is: for (expr1; expr2; expr3) statement. The first expression (expr1) is evaluated (executed) once unconditionally at the beginning of the loop.
Introduction to PHP for statement. The for statement allows you to execute a code block repeatedly. The syntax of the for statement is as follows: <?php for (start; condition; increment) { statement; } Code language: HTML, XML (xml) How it works. The start is evaluated once when the loop starts. The condition is evaluated once in each iteration.
9 sty 2024 · PHP’s ‘for’ loop is a fundamental construct for iterating over ranges or arrays, enabling tasks from simple data listing to complex algorithm implementation. This tutorial provides an in-depth understanding, reinforced with practical examples taking you from basic to advanced usage. Getting Started with ‘for’ loops.
for — loops through a block of code until the counter reaches a specified number. foreach — loops through a block of code for each element in an array. You will also learn how to loop through the values of array using foreach () loop at the end of this chapter.
PHP also supports the alternate "colon syntax" for for loops. for (expr1; expr2; expr3): statement ... endfor; It's a common thing to many users to iterate through arrays like in the example below.
For loops are simple loops which helps us iterate over an iterable variable by using an index. There are two types of for loops - a simple (C style) for loop, and a foreach loop. For loops are very useful when we need to iterate over an array and refer to member of the array using a changing index.
