I want to replace a repetitive word of an array, so I do this:
$thisarray = preg_replace ("/HELLO/"), "BYE", $thisarray);
echo $thisarray[0];
That works perfect... the problem comes when I use a PHP SIMPLE HTML DOM PARSER instruction "plaintext"
$thisarray = preg_replace ("/HELLO/"), "BYE", $thisarray);
echo $thisarray[0]->plaintext;
It says: Notice: Trying to get property of non-object in
$thisarray is either an array of strings or an array of simple_html_dom instances. Pick one.
If it's the former, they won't even be objects, and thus can't have a plaintext property.
And if it's the latter, be careful passing it to a function that expects strings. A function that wants strings will either choke on objects or stringify them as needed. Even assuming a simple_html_dom knows how to convert itself to a string, preg_replace will return a string (or an array of strings) as well. That means once preg_replace does its thing and you replace $thisarray with the return value, no matter what it was before, now you have an array of strings. See above.
First of all, preg_replace is not a function that is performant if you just want to replace a world instead of a pattern. For your case, str_replace is better.
Then, you just misuse $thisarray variable. Before your function, it is an object, after, it is no longer an object as preg_replace returns a string OR an array.
so, you can have sort of cleaner code with that :
$textToReplace = array('/HELLO/','other world to replace');
replacementText = array('BYE','other replacemnt text');
$cleanText = str_replace($textToReplace,$replacementText,$thisarray[0]->plaintext);
echo $cleanText;
