The problem reduces to counting \n characters, so is there a function that can do it on a huge strings, since explode() wastes too much memory.

split("\r\n|\r|\n", -1); if you look at the docs here:docs.oracle.com/javase/7/docs/api/java/lang/… it has more information. since java 1.1 there is a LineNumberReader. see my answer below.
Use readlines() to get Line Count This is the most straightforward way to count the number of lines in a text file in Python. The readlines() method reads all lines from a file and stores it in a list. Next, use the len() function to find the length of the list which is nothing but total lines present in a file.
Instantiate a String class by passing the byte array obtained, as a parameter its constructor. Now, split the above string into an array of strings using the split() method by passing the regular expression of the new line as a parameter to this method. Now, find the length of the obtained array.
substr_count should do the trick:
substr_count( $your_string, "\n" ); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
