- The eAccelerator and XCache PHP performance extensions are known to cause issues. If you're using either of those and are having problems, please disable them while you do your import. Add the following lines:
php_value eaccelerator.enable 0
php_value xcache.cacher off
php_value xcache.optimizer off
Syntax
if
if ( ( $A != "null" ) && (( $A === "true" ) || ( $A == "true" ) || ( $A <= 12 ) ) ) {
/* code code code */
}
else
{
/* code code code */
}
- abbreviation (as in C):
(something) ? (if true do this) : (else do this)
for / foreach
switch
switch ($something) {
case 0:
echo "something is 0";
break;
case "hello":
echo "something is $something";
break;
}
Strings
- joining strings:
$string1 . "string 2" . $_GLOBAL['string3'];
Array
- basic
Array("one", "two", "3" );
- with index:
Array( 1 => "one", 2 => "two", 3 => "3" );
- 2 dimensions
My algorithms

}
Others algorithms
simple glob() type replacement:
$files = preg_find('/./', $dir);
recursive?
$files = preg_find('/./', $dir, PREG_FIND_RECURSIVE);
pattern match? find all .php files:
$files = preg_find('/\.php$/D', $dir, PREG_FIND_RECURSIVE);
sorted alphabetically?
$files = preg_find('/\.php$/D', $dir, PREG_FIND_RECURSIVE|PREG_FIND_SORTKEYS);
sorted in by filesize, in descending order?
$files = preg_find('/./', $dir,
PREG_FIND_RECURSIVE|PREG_FIND_RETURNASSOC |PREG_FIND_SORTFILESIZE|PREG_FIND_SORTDESC);
$files=array_keys($files);
sorted by date modified?
$files = preg_find('/./', $dir,
PREG_FIND_RECURSIVE|PREG_FIND_RETURNASSOC |PREG_FIND_SORTMODIFIED);
$files=array_keys($files);
