PHP/MySQL: Warning: mysql_query(): Unable to save result set ...
Today i found a error in a tiny script i was working on.
The error Message looked like this:
Warning: mysql_query() [function.mysql-query]: Unable to save result set in /var/www/example.php on line 55
First i found a few hints about repairing or optimizing MySQL tables, but this did not work out.
After a few debugging outputs a realized that the query was not properly written.

PHP: phpMyAdmin3 - deactivate slider effects
For all of you who liked phpMyAdmin2 where all relevant information was visible at any time, sould be annoyed be the new slider effects in phpMyAdmin3.
I did a short search for the config value to change this and found this solution.
Add this to your config.inc.php:
// Change slider behaviour
$cfg['InitialSlidersState'] = 'open';
$cfg['InitialSlidersState'] = 'open';
And your sliders will start in visible state.

PHP: floor() and ceil() are slow!
A workmate mentioned, that floor($i) could be replaced with (int)$i.
I found this very interresting and did some researched about that.
floor($i); will return a float that will have the lower value of $i.
A cast will just convert $i to an integer which will cut of all decimals.
So by symptoms, these two methods are equivalent. Even if floor returns a float, PHP does dynamic casting of its variables.
PHP: Do NOT rebuild preg_* functions!
In a PHP Project i am currently helping out, i found this function:
/**
* Replaces every char in $str that does is not in $valid array
*
* @param array $valid
* @param string $str
* @return string
*/
function cleanString($valid, $str) {
$ret = '';
$len = strlen($str);
for($i = 0; $i < $len; ++$i) {
if(in_array($str[$i], $valid, true)) {
$ret .= $str[$i];
}
}
return $ret;
}
* Replaces every char in $str that does is not in $valid array
*
* @param array $valid
* @param string $str
* @return string
*/
function cleanString($valid, $str) {
$ret = '';
$len = strlen($str);
for($i = 0; $i < $len; ++$i) {
if(in_array($str[$i], $valid, true)) {
$ret .= $str[$i];
}
}
return $ret;
}
It is a simple function for replacing chars. It works quite well, but was mainly only used for checking [^a-z0-9]. So i tested the speed of this code.

PHP: Easy Memcache handling
In a current project of mine i needed the use of a universal caching system.
After testing a little bit with APC i found memcache that will do the job perfectly.
So i wrote a few tiny functions for easy memcache handling.
