Si se evalúa como true, el bucle continúa y se ejecutan la/sy. En el comienzo de cada iteración, se evalúa expr2. La sintaxis de un bucle for es: La primera expresión ( expr1) es evaluada (ejecutada) una vez incondicionalmente al comienzo del bucle. Note: Before PHP 7.1.0, list () only worked on numerical arrays and assumes the numerical indices start at 0. In computer programming, foreach loop (or for-each loop) is a control flow statement for. Los bucles for son los más complejos en PHP. Strings can not be unpacked and list () expressions can not be completely empty. list () is used to assign a list of variables in one operation. The foreach statement iterates over all elements in an array, one at a time. It loops over the array, and each value for the current array element is assigned to $value, and the array pointer is advanced by one to go the next element in the array. Like array (), this is not really a function, but a language construct. PHP provides you with the foreach statement that allows you to iterate over elements of an array, either an indexed array or an associative array. The foreach loop is mainly used for looping through the values of an array.
