What’s missing with Switch Statement?

[rahulephp]

In below switch statement, it should have to print only "T","E","S" characters as string "testing" contains these words.
But it is printing all characters including "X" and "Z".
I can’t use "break;" because it will break operation after first case. (After matching "T" with word "testing") but I want to continue the operation even after every case to find the next character.

Please advice if anything is missing.

switch(true)
{
	case stristr('testing','t'):
	echo "T"."<br>";
	
	case stristr('testing','x'):
	echo "X"."<br>";
	
	case stristr('testing','e'):
	echo "E"."<br>";
	
	case stristr('testing','z'):
	echo "Z"."<br>";
	
	case stristr('testing','s'):
	echo "S"."<br>";
}

If you don't have break statement at the end of case than php will go on executing the statements of the following case. switch
