问题 I have a program that loads lines from a user file, then selects the last part of the String (which would be an int) Here's the style it's saved in: nameOfValue = 0 nameOfValue2 = 0 and so on. I have selected the value for sure - I debugged it by printing. I just can't seem to save it back in. if(nameOfValue.equals(type)) { System.out.println(nameOfValue+" equals "+type); value.replace(value, Integer.toString(Integer.parseInt(value)+1)); } How would I resave it? I've tried bufferedwriter but

问题 I'd like to use the 'include' keyword in php to randomly select a file from a folder and output the contents. How would I do this? Thanks. 回答1: Assuming you know the folder where the files are and that the files are PHP files: $phpFiles = glob('/path/to/files/*.php'); if (empty($phpFiles) === false) { $randomFile = $phpFiles[array_rand($phpFiles)]; include($randomFile); } 回答2: glob() would read filenames into array. and then you can shuffle this array and pick a random item. 回答3: use glob to
