gregaryb Posted October 31, 2023 Share Posted October 31, 2023 (edited) The following code is not working as I intuitivel expect it to... $nI = strpos($strText, "'"); $strText = substr_replace($strText, "XXXX", $nI); echo $strText $strText contains "Greg's Native Landscapes" After the call to substr_replace $strText contains GregXXXX I am expecting it to contain "GregXXXXs Native Landscapes" So how the devil is this function working? And how do I obtain the result I am expecting? This function is unbelievably confusing! If I do this instead: $nI = strpos($strText, "'"); $strText = substr_replace($strText, "XXXX", 100); echo $strText I get "Greg's Native LandscapeXXXX". WTF??? Am I really going to have to code my own string library with functions that behave in the ways I am accustomed to!

Don E Posted October 31, 2023 Share Posted October 31, 2023 To achieve your initial goal, try this: substr_replace("Greg's Native Landscapes","XXXX",4, 1); 4 represents the position as defined in your $n1 variable, and 1 represents the 'length' of characters to replace, which in this instance only 1, the apostrophe.
