Few Questions...

[MemphiS]

Just out of interest im sure this question has been asked before..

 

Difference?Speed? between print(); and echo();

 

adding () make it slower/faster instead of just going: print ""; or echo "";

 

Just interested...

 

Another question.

 

while coding.. Example:

 

<?php
$go = $_POST['the'];

if ($go==1){ ...code to excute }
?>

/* Other example */

<?php
if ($_POST['the']){ ...code to excute }
?>

 

Just interested if theres any real point to assigning the post to a variable? Save speed by not setting a variable to it?

 

Thanks

with $_POST/$_GET variables... you almost always want to make them more safe... so... i subscribe to this school of thought

 

<?php
$go = htmlentities($_POST['the']);

if ($go==1){ ...code to excute }
?>

 

in the long run... its really down to the programmer...what works for you... and including the ()'s on print/echo... really arnt necessary... people use em... but i dont see a point in em... just making your code harder to read :-)

hmm thanks for your reply.. =) i kinda like using the ()  makes it neater to read well i find so

 

though you could still use $_POST['the']

 

and place

 

$_POST = array_map('htmlentities', $_POST);

 

which would cover all $_POST[]

also..

 

you can just check the data submited by the user before it goes anywhere.

<?php

if (!ctype_alnum($_POST['the']){ print("Invalid data."); }elseif (ctype_alnum($_POST['the']){ ...code to excute }

?>

hmm
