give example how to store and retrieve variables

I agree. As a total novice to PHP programming, examples help me learn faster.

done

i try


$myVar2 = 'http://www.google.com';
$storage->setObj ('link', $myVar2);
$storedVar = $storage->getObj ('storedVar');

echo 'Dump for storedVar: ';

var_dump ($storedVar);


i dont c difference

how to to getvar('link')
and get the google link as result



in the example of the other author it is so easy to put en get vars

at last found it


echo "<hr>";
$myVar2 = 'http://www.google.com';
$storage->setObj ('link', $myVar2);
$storedVar = $storage->getObj ('link');

echo 'Dump for link: ';

var_dump ($storedVar);
echo "<hr>";
echo $storedVar;

$br='<br>';
echo 'format '.$storedVar['format'].$br;
echo 'number '.$storedVar['number'].$br;

not working

As you can see dumping $storedVar, it is a stdObject not an array. So that:

$br='<br>';
echo 'format '.$storedVar->format.$br;
echo 'number '.$storedVar->number.$br;

will work

tx

almost there

what gets into $storedvar if link does not exist?


$storedVar = $storage->getObj ('link');

when key not exist

echo "<hr>";
$storedVar = $storage->getObj ('zzz');

echo 'zzz: '.$storedVar;
echo "<hr>";
var_dump ($storedVar);



it blocks just on hr

getobj ld return errorcode then
