str_replace()
It's your best friend when you have a string, and wanna replace part of the string with other things or other strings or anything.
It takes three arguments
str_replace("word to look for", "word to replace with", "original string")
$str = "hello world";
$newStr = str_replace("world", "dbestech", $str);
print($newStr);This would print
hello dbestech
Another good exmple when you do url manupulatation for seo in PHP or Laravel. You wanna replace the white space with "-". So str_replace() comes to rescue you.
$url = "the best backend framework";
$newUrl = str_replace(" ", "-", $url);
print($newUrl);This would print somethng like below
the-best-backend-framework
