Example #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);}?>
The above example will output something similar to:
array(1) {
[0]=>
array(2) {
[0]=>
string(4) "test"
[1]=>
int(0)
}
}
array(1) {
[0]=>
array(2) {
[0]=>
string(4) "test"
[1]=>
int(0)
}
}
