H2S45: Variable management in PHP:

Hu: Variables are a powerful | paradigm that can be externally | discussed; chess players are familiar with this idea; for instance, the simplicity of the N’s movement, analogous to the fundamental | complexity of a variable, does not prevent us from continuously discussing its applications, in all subsequent b-ps // cite a MIC, maybe ch-5 N’s mobility:

H3S1: Silent variables, to pass latent | data:

Hu: Silent variables can pass latent | data that phenotypically | appears in a later page; this can be coordinated with URL-management<WP.MIC-H2S41> and , if necessary, some scraping functions.

H4S1: Academic connection<fbno>: genotype vs phenotype, biology:

// add research

H3S2: Included globals<Turing!> to mass control strings:

<WP.MIC-H2S41><php.net>: The scope of a variable is the context within which it is defined. For the most part all PHP variables only have a single | scope. This single scope spans included and required files as well<important!>.

H4S1: In-function variable calls are local, not global, by default<Turing>:

<php.net>: However, within user-defined | functions a local function | scope is introduced. Any variable used inside a function is by default limited to the local function scope. You may notice that this is a little bit different from the C language in that global variables in C are automatically available to functions unless specifically overridden by a local definition. This can cause some problems in that people may inadvertently change a global variable. In PHP global variables must be declared global inside a function if they are going to be used in that function. Eg:

$a = 1;
$b = 2;

function Sum()
    global $a, $b;

    $b = $a + $b;

echo $b;

Output=3. By declaring $a and $b global within the function, all references to either variable will refer to the global version. There is no limit to the number of global variables that can be manipulated by a function.

H4S2: $GLOBALS is synonymous with the global declaration:

The $GLOBALS array is an associative array with the name of the global variable being the key and the contents of that variable being the value of the array | element. Notice how $GLOBALS exists in any scope, this is because $GLOBALS is a superglobal<hinge!><ch-8> Hu: All function calls that are routed through an include, such as an included | function that calls its own include, need to use a global variable, for all defined | variables.

H3S3: Local to global pass<Turing>:

H4S1: How to pass a local variable in a function to external the function; that variable cannot be directly called outside the function.

return $result; // this line is inside the function
$result = full_post_list_select1(); // this line is outside the function.

Now, $result, local, in its exact form, has been transferred into a $result-global, that can be used, generally #<WP.MIC-H2S35,H3S3.H4S8 return>
