PHP

server

• 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)

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
