(PHP 5 >= 5.2.0, PHP 7)
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.
示例 #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
