RegexIterator::accept — Get accept status
Matches (string) RegexIterator::current() (or RegexIterator::key() if the RegexIterator::USE_KEY flag is set) against the regular expression.
此函数没有参数。
TRUE if a match, FALSE otherwise.
Example #1 RegexIterator::accept() example
This example shows that only items matching the regular expression are accepted.
<?php
$names = new ArrayIterator(array('Ann', 'Bob', 'Charlie', 'David'));
$filter = new RegexIterator($names, '/^[B-D]/');
foreach ($filter as $name) {
echo $name . PHP_EOL;
}
?>
以上例程会输出：
Bob Charlie David
