Hey guys I need a php thing to be done for me, or if you have other suggestions I would highly appreciate. Basically I have a txt file with a lot of rows (100) like this: this is a random text on line 1 with a $keyword thats awesome. this is another random text on line 2 with $keyword2 thats super cool. this is a boring text on line 3 with $keyword3 thats boring. ..... bla bla bla $keyword100 blabla. Now I need to change everytime the keywords, to other ones. And you can imagine by going find-replace one by one it's taking A LOT of time. I would love if someone would help me to make a small php script that will have a text form where I enter all the 100 keywords (1 per line) and it will change them in the whole text file. So, if I enter: apple mouse ... the output would be: this is a random text on line 1 with a APPLE thats awesome. this is another random text on line 2 with MOUSE thats super cool. Hope I explained well. If there is another way to do this, please tell me !
