Is htaccess-like password protect from PHP possible? -

-

You know that the htaccess password protection of a folder displays the system's default modal window with a password prompt; I would like to know that I can achieve that functionality, but only after programming, whether it is needed or not.

Which means that the same URL may need password protection in two different situations, so if some of my conditions have not been met, then I like it if I Can easily throw the "box" without the need of own session controller code (or implement) in PHP from PHP (PHP)

The short answer is yes - see example 1, on which I'm down Defense Published: 

  & lt ?? Php if (! Isset ($ _ SERVER ['PHP_AUTH_USER'])) {header ('WWW-authentication: original realm = "my area"'); Header ('http / 1.0 401 unauthorized'); Repeat 'Text To Read If User Cancel Cancel Button'; Go out; } Else {echo "
 Hello {$ _SERVER ['PHP_AUTH_USER']}. & Lt; / p & gt;"; Echo "& lt; p & gt; You entered {$ _SERVER ['PHP_AUTH_PW']} as your password. & Lt; / p & gt;"; }? & Gt;

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...
