### Description
set max_execution_time=5
The following code:
```php
<?php
$i=1;
while($i<=50000000000000000)
{
echo "The number is " . $i . "<br>";
$i++;
}
?>
get msg:
Fatal error: Maximum execution time of 5 seconds exceeded in D:\Samples\a.php on line 5
```
test sample: ext\standard\tests\strings\crypt_sha256.phpt
```
--TEST--
crypt() SHA-256
--FILE--
<?php
$tests = array(
1 => array(
'$5$saltstring',
'Hello world!',
'$5$saltstring$5B8vYYiY.CVt1RlTTf8KbXBH3hsxY/GNooZaBBGWEc5'
),

'This is just a test',

),
5 => array(
'$5$rounds=1400$anotherlongsaltstring',
'a very much longer text to encrypt. This one even stretches over morethan one
line.',
'$5$rounds=1400$anotherlongsalts$Rx.j8H.h8HjEDGomFU8bDkXm3XIUnzyxf12oP84Bnq1'
),
6 => array(

'we have a short salt string but not a short password',
'$5$rounds=77777$short$JiO1O3ZpDAxGJeaDIuqCoEFysAe1mZNJRs3pw0KQRd/'
),
7 => array(
'$5$rounds=123456$asaltof16chars..',
'a short string',
'$5$rounds=123456$asaltof16chars..$gP3VQ/6X7UUEW3HkBn2w1/Ptq2jxPyzV/cZKmF/wJvD'
),
8 => array(
'$5$rounds=10$roundstoolow',
'the number of rounds is too low',
'*0'
),
9 => array(
'$5$rounds=1000000000$roundstoohigh',
'the number of rounds is too high',
'*0'
)
);
foreach ($tests as $iter => $t) {
$res = crypt($t[1], $t[0]);
if ($res != $t[2]) echo "Iteration $iter failed.
Expected: <$t[2]>
Got <$res>\n";
}
echo "Passes.";?>
--EXPECT--
Passes.
```
Running time is more than 5 seconds
I don't know if this is php's strategy to let the crypt function not be limited by the
max_execution_time
