Also if you had anymore questions please do so.

Well I think we are ready, so lets get started.......

Now here are the following I will show you guys in this references info:

The list of commands/directions of PHP advanced

Advanced Operators:

mysql_list_tables(,[]);
mysql_list_fields(,,[]);
mysql_query(,[]);
mysql_fetch_array(,);
mysql_fetch_assoc();
mysql_fetch_object(,[],[]);
mysql_fetch_row();

Code: [Select]
// Example using fetch_array
while ($result_row = mysql_fetch_array($result,MYSQL_ASSOC)){
echo "Field 1 is: {$result_row['field1']}";
}

// Example using fetch_object
while ($result_obj = mysql_fetch_object($result)) {
echo "Field 1 is: " . $result_obj->field1;
}

mysql_affected_rows([]);
mysql_num_rows();
mysql_num_fields();
mysql_real_escape_string(,[]);
mysql_close([]);

File Reading/Writing:
fopen(,,[],[]);
fread(,);
fwrite(,,[]);
fseek(,,[]);
fclose();
is_readable();
is_writeable();

Code: [Select]
// Example of writing to file

$file = fopen("hellobob.txt","w");

if ($file) {
fwrite($file,"This is a line of text");
fclose($file);
}

// Example of reading from file

$fileread = fopen("hellobob.txt","r");

if ($fileread) {
$text = fread($fileread,100);
fclose($fileread);

echo "Read in: $text";
}

File/directory Handling:
file_exists();
is_file();
dirname();
is_dir();
mkdir(,[],[],[]);
rmdir(,[]);
rename(,,[]);
copy(,,[]);
chmod(,);
unlink(]);

Code: [Select]
// Example of using is_file, copy, and unlink to rename file.

if (is_file("hellobob.txt")) {
copy("hellobob.txt","goodbyebob.txt");
unlink("hellobob.txt");
}

// Example of file_exists and rename

if (file_exists("goodbyebob.txt")) {
rename("goodbye.txt","helloagainbob.txt");
}

Function Handling:
create_function(,);
call_user_func( [, [, [, ... ]]]);
call_user_func(array(,)[, [, [,
... ]]]);
call_user_func_array(,);
function_exists();

Code: [Select]
// Example of creating anonymous function (returns the value 6)

$myNewFunction = create_function('$param1,$param2','return $param1 * $param2;');
echo "Result is: " . $myNewFunction(2,3);

// Example of calling class method using parameter

class MyClass {
function showMessage($test = "") {
echo "Welcome to DIC! $test";
}
