function my_function() {
$var1 = "123";
$var2 = "abc";
return $var1;
}
Sometimes I want to use $var2 but calling my_function() will simply return what the function returns ( $var1 ).
Is there any trick to retrieve the $var2 data ? maybe my_function($var2) ..
Regards.
Just pass the arguments by reference, e.g.
$var1 = "";
$var2 = "";
function my_function(&$var1, &$var2) {
//^ ^ See here
$var1 = "123";
$var2 = "abc";
}
my_function($var1, $var2);
//Now you can use $var1 and $var2 for you next function with the new values.
And if you want to read more about references in general see the manual: http://php.net/manual/en/language.references.php
Another alternative is declaring $var2 as a global inside the function.
$var2 = "hello";
function my_function() {
global $var2;
$var1 = "123";
$var2 = "abc";
return $var1;
}
Now my_function() will be able to access $var2 declared outside its scope and change its value.
$var1 = '321';
echo $var1; // will be '321' obviously
$myVar = my_function();
function my_function()
{
$var1 = '123';
return $var1;
}
echo $var1; // will be '321'
echo $myVar; // will be '123';
