Answer 1

1- you should explain what your function do, because may it return false by default or by a logic error

2- use this function preg_match($pattern, $subject, $matches); and the pattern is "/صباح/" Like this:

       $strings="تم اكل الدجاجه صباح الجمعه";
$pattern="/صباح/";
$replacement="ص";

$search =preg_match($pattern, $strings);
if($search ==1){
 echo "yes! it's here!";
}else{
echo "No!, it's not here!";
}

//if you want to replace the statement you can use this function  
$strings=preg_replace($pattern, $replacement,$strings);
echo $strings;
//The result will be : 
//تم اكل الدجاجه صباح الجمعه
