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) } }
