Wiki: PHP intval - value to int conversationwiki

intval — Возвращает целое значение переменной
Описание

int intval ( mixed $var [, int $base = 10 ] )

Возвращает целое значение переменной var, используя указанное основание системы исчисления base для преобразования (по умолчанию основание равно 10). intval() нельзя использовать с объектами, попытка это сделать вызовет ошибку уровня E_NOTICE и вернет значение 1.
Список параметров
  • var - Скалярное значение для конвертации в целое
  • base - Основание системы исчисления для преобразования

Замечание:
Если base равно 0, основание системы исчисления определяется форматом параметра var:
  • если строка включает префикс "0x" (или "0X"), основание выбирается равным 16 (шестнадцатеричным);
  • иначе, если строка начинается с "0", основание равно 8 (восьмеричное);
  • иначе, основание выбирается равным 10 (десятеричным).

Возвращаемые значения
Целое значение переменной var в случае успеха, или 0 в случае неудачи. Для пустых массивов возвращается 0, для непустых возвращается 1.

Максимальное значение зависит от операционной системы. В 32-х битных системах максимальное знаковое целое лежит в диапазоне от -2147483648 до 2147483647. Так, например, в такой системе, intval('1000000000000') вернет 2147483647. Максимальное знаковое целое значение для 64-х битных систем - 9223372036854775807.

Для строк функция скорее всего вернет 0, хотя это зависит от первого символа в строке. Применяются общие правила преобразований в целые.
Примеры

<?php
echo intval(42); // 42
echo intval(4.2); // 4
echo intval('42'); // 42
echo intval('+42'); // 42
echo intval('-42'); // -42
echo intval(042); // 34
echo intval('042'); // 42
echo intval(1e10); // 1410065408
echo intval('1e10'); // 1
echo intval(0x1A); // 26
echo intval(42000000); // 42000000
echo intval(420000000000000000000); // 0
echo intval('420000000000000000000'); // 2147483647
echo intval(42, 8); // 42
echo intval('42', 8); // 34
echo intval(array()); // 0
echo intval(array('foo', 'bar')); // 1
?>

Resolved: How to clear browser cache when re-uploading image with same filename, in php?
posted by admin on June 18, 2016
I have a listing of items, that also contains an image thumbnail. Sometimes I need to change the thumbnail image, but keep the filename the same. Is there a way to force the browser to download the newly uploaded image, instead of grabbing one from the browser cache?

This is very pertinent when people update their avatars, which causes confusion for some users, who keep seeing their old avatar, until they clear the browser cache, or restart the browser.Read more

    Resolved: error :should not be called statically, assuming $this from incompatible context. only on my machine
    posted by admin on June 3, 2016
    My team members wrote the model function calls in the controller statically such as:

    $data = ModelName::functionName($param);

    while it should be called dynamically such as:

    $model = new Model();
    $data = $model->functionName($param);

    mostly all the calls are made statically. the code is working on the server and on their local machines except for mine. And the static calls are too many to fix without rewriting huge code base.

    I always update my project via composer. My php version is 5.4.

    anyone might know what this is about?Read more
