RegexIterator::setPregFlags — Sets the regular expression flags
说明
public RegexIterator::setPregFlags(int$pregFlags): void
Sets the regular expression flags.
参数

pregFlags -
The regular expression flags. See RegexIterator::__construct() for an overview of available flags.
返回值

范例
示例 #1 RegexIterator::setPregFlags() example
Creates a new RegexIterator that filters all entries with where the array key starts with 'test'.
<?php
$test = array ('test 1', 'another test', 'test 123');
$arrayIterator = new ArrayIterator($test);
$regexIterator = new RegexIterator($arrayIterator, '/^test/', RegexIterator::GET_MATCH);
$regexIterator->setPregFlags(PREG_OFFSET_CAPTURE);
foreach ($regexIterator as $key => $value) {
var_dump($value);
}
?>
以上例程的输出类似于：
array(1) {
[0]=>
array(2) {
[0]=>
string(4) "test"
[1]=>
int(0)
}
}
array(1) {
[0]=>
array(2) {
[0]=>
string(4) "test"
[1]=>
int(0)
}
}
