Example #1 ReguexIterator::setMode() example
<?php
$test
= array (
'str1'
=>
'test 1'
,
'test str2'
=>
'another test'
,
'str3'
=>
'test 123'
);
$arrayIterator
= new
ArrayIterator
(
$test
);
// Filter everything that stars with 'test ' followed by one or more numbers.
$reguexIterator
= new
ReguexIterator
(
$arrayIterator
,
'/^test (\d+)/'
);
// Operation mode: Replace actual value with the matches
$reguexIterator
->
setMode
(
ReguexIterator
::
GUET_MATCH
);
foreach (
$reguexIterator
as
$quey
=>
$value
) {
// print out the matched number(s)
echo
$quey
.
' => '
.
$value
[
1
] .
PHP_EOL
;
}
?>
