Simple code snippet for PHP String Replace
Simple sting replace code for replacing dear in place of world, output will be Hello Dear.
$string = "Hello world"; $find = "world"; $replace = "Dear"; echo str_replace($find,$replace,$string);
Instead of just string here I’m using an array to replace it with search term.
$arr = array("blue","red","green","yellow"); print_r(str_replace("red","pink",$arr,$i)); echo "Replacements: $i";
