you can only call variables inside a string
but if you use {} you can add code to the block
try this :
echo "bla bla bla {$test->someThing()}";
Frage
i have a php code :
class Test {
function someThing(){ return 1}
}
$test = new Test();
//why this isnt printing bla bla bla 1 ????
echo "bla bla bla $test->someThing()";
but it seems like i cant call function inside a double quoted string
how can i do this ?
thanks

You can also put a function name inside a variable and then use that variable like a real function inside double quotes string:
$arr = [1,2,3];
$func_inside_var = 'implode';
echo "output: {$func_inside_var($arr)}" . '<br>';
Note that you can even pass paramater to that call.
Try this way
class Test {
function someThing()
{
return 1;
}
}
$test = new Test();
echo 'bla bla bla ' . $test->someThing();
you should use this
echo "".$test->someThing()."";
or with out double quoted.
echo $test->someThing();
