在我的SQL中,如果我想拉出一栏价值等于若干价值之一的记录,我可以这样说:
SELECT * FROM myTable WHERE myColumn IN(1,5,7)
是否唯一能与OR一道在PHP中完成类似内容的方法?
if($category == 1 || $category == 5 || $category == 7) {
// do something
}

见http://us3.php.net/manual/en/Function.in-array.php。
E.g.:
$list = array(1, 5, 7);
if (in_array($category, $list)) {
// do something
}
或者,更紧的是:
if (in_array($category, array(1, 5, 7))) {
// do something
}
Sure in_array, i.e
if( in_array( $category, array( 1, 5, 7 ) ) ) {
是, http://php.net/manual/en/Function.in-array.php“rel=“nofollow”>in_array 。
如果有面面面面面面面面面面面面面面面面面,你就可以检查价值。
$categories =array(1,5,7);
if (in_array($category, $categories))
{
//do stuff
}
