[PHP Obfuscation]

Shoot, sorry, I don't see a place to move it...

[PHP Obfuscation]

I found it a fun learning experience to make something as simple as "HELLO WORLD!" into a difficult process.

 

I obfuscated my PHP below to just echo "HELLO WORLD!". Anyone else have a better example to echo "HELLO WORLD!"?

 

<?php
// Output = HELLO WORLD!
function __e($_){echo$_;
}function __($_){__e(chr
($_));}function _a(){$__
=func_get_args();foreach
($__ as$k=>$v)$a[$k]=$v;
return$a;}foreach(_a(7,4
,+11,11,14,-33,22,14,17,
11,3,-32)as$k=>$v){__(65
+$v);}

 

Give it a shot, it more difficult to think of creative ways to make something out of the box like this.

[[SOLVED] Round Timestamp to Nearest 15 Minutes]

I think I have figured it out!

 

<?php

function roundTime($timestamp, $precision = 15) {
  $timestamp = strtotime($timestamp);
  $precision = 60 * $precision;
  return date('Y-m-d H:i:s', round($timestamp / $precision) * $precision);
}

// 2009-06-29 10:45:00
echo roundTime('2009-06-29 10:48:13');

?>

[[SOLVED] Round Timestamp to Nearest 15 Minutes]

I have timestamps in a database that are from the creation time of the records. These timestamps are something like 2009-06-29 08:54:32.

 

In this case, I would like to round this timestamp to the nearest 15 minute increment (00:00, 00:15, 00:30, or 00:45) so the end result for 2009-06-29 08:54:32 would be 2009-06-29 09:00:00.

 

If the time stamp was 2009-06-29 09:07:17, then the end result would still be 2009-06-29 09:00:00.

 

Another option, if possible, would be to always round up. Maybe have an argument in the function to round to nearest or to round up/down?

 

Can someone help me build a function to do this? It would be greatly appreciated!

 

Thank you!

[Sorting Hex Colors]

I have an array of hexadecimal color codes:

 

Array
(
    [0] => 2060A0
    [1] => 204080
    [2] => 206080
    [3] => 000000
    [4] => A0A0A0
    [5] => C0C0C0
    [6] => 808080
    [7] => E0E0E0
    [8] => 404040
    [9] => 80A0A0
    [10] => 202020
    [11] => 002020
)

 

I would like to sort the array by color.  I tried a natsort() and that didn't work the way I would have liked.

Does anyone have any ideas on how to accomplish this?

 

Thanks!

[pdo_mysql vs phpinfo]

I also tried the instructions here: http://discussions.apple.com/message.jspa?messageID=8418099#8418099

I got to the configure command and had this problem:

 

checking for MySQL support for PDO... yes, shared
checking for mysql_config... /usr/local/mysql/bin/mysql_config
checking for mysql_query in -lmysqlclient... no
configure: error: mysql_query missing!?

[pdo_mysql vs phpinfo]

I wish.  There is macports.

 

How would I go about reinstalling Apache, PHP and MySQL without junking up my system or breaking the default install?

[pdo_mysql vs phpinfo]

Thank you!  Can you help me debug what I have found?

 

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20060613/pdo_mysql.so' - (null) in Unknown on line 0

 

I also found this from a few days ago, but I haven't seen it in the logs recently.

dyld: Library not loaded: /usr/local/mysql/lib/libmysqlclient.16.dylib
  Referenced from: /usr/lib/php/extensions/no-debug-non-zts-20060613/pdo_mysql.so
  Reason: no suitable image found.  Did find:
/usr/local/mysql/lib/libmysqlclient.16.dylib: mach-o, but wrong architecture

 

Any ideas?

[pdo_mysql vs phpinfo]

Any ideas of where/what logs I should be looking at?  What am I looking for?

[pdo_mysql vs phpinfo]

I have confirmed that I am editing the correct php.ini file.  I also have the GD module installed.  Once I commented the extension line for that module I no longer saw GD support with php -m or phpinfo();.  After uncommenting it, I saw it in both locations again.

[pdo_mysql vs phpinfo]

Hmmm, I am editing the php.ini file listed on the info page as the "Loaded Configuration File".

[pdo_mysql vs phpinfo]

If I comment out the extension line, rerun php -m, pdo_mysql is no longer there.  Once I uncomment the line again, I see pdo_mysql in php -m, but not with phpinfo();.

[pdo_mysql vs phpinfo]

Yes, it is uncommented.

[pdo_mysql vs phpinfo]

I am running Apache/PHP on Leopard with the base install provided by Apple.  I need support for pdo_mysql so I followed the directions at http://starfog.com/node/52.  When I run php -m from the command line, I see that both PDO and pdo_mysql are listed.  If I check my phpinfo page, I do not see pdo_mysql anywhere.  What can I do to get pdo_mysql support on Leopard?

 

Thanks!

[Trunicate string]

<?php
$string = 'The quick brown fox jumped over the lazy dog.';
echo substr($string, 0, 25); // 'The quick brown fox jumpe'
?>

 

The last parameter, 25, is the number of characters to print.

See http://us2.php.net/substr for more information.

[String to Array]

<?php
$test = 'Paths.Images.Icons';
$out = array();
foreach (array_reverse(explode('.',$test)) as $v) $out = array($v => $out);
print_r($out);
?>

 

Wow!  That is genus and so simple!

 

Also, I compared the two slightly different functions, see below.

<?php
// Sasa's Function
function strToNestedArray($string) {
   $out = array();
   foreach (array_reverse(explode('.',$string)) as $v) $out = array($v => $out);
   return $out;
}

// uniflare Function
function str_to_nested_array($string) {
  $rVerse = array_reverse(explode('.',$string));
  foreach ($rVerse as $v) $out = array($v => $out);
  return $out;
}

$str = "path.to.something.that.is.really.neat";

echo "100k call * 10 benchmarking: <br/><br/>";
echo "Sasa's Test<br/>";
for ($y = 0; $y < 10; $y++) {
$start = microtime(true);
for ($x = 0; $x < 100000; $x++) {
   $structure = strToNestedArray($str);
}
$time = microtime(true) - $start;
echo $time . "<br/>";
}

echo "<br/>uniflare 's Test<br/>";
for ($y = 0; $y < 10; $y++) {
$start = microtime(true);
for ($x = 0; $x < 100000; $x++) {
   $array = str_to_nested_array($str);
}
$time = microtime(true) - $start;
echo $time . "<br/>";
}

 

Here are the results:

100k call * 10 benchmarking:

I really appreciate everyone's help and snippets.  Thanks everyone!

[String to Array]

Sorry, one more question, is it possible to call the function with the only argument being the input string?

 

<?php
$array = str_to_nested_array('Paths.Images.Icons');
?>

[String to Array]

That is perfect!

 

Can you please explain the code a little bit?  I have never used a function within a function like this...

 

Thanks again!

[String to Array]

I have a string that I need converted to a nested array.  See code below:

// Input string
$string = 'Paths.Images.Icons';

/*
Need the following back:
Array
(
    [Paths] => Array
    (
        [images] => Array
        (
            [icons] => Array
            (
            )
        )
    )
)

*/

 

I need a function that will parse the input string and generate a nested array based on the periods in the input string.

 

Can someone help me create a function to do this?

 

Thanks!
