On failure, filegetcontents () will return false. It also returns FALSE if there is no more data to be read. string filename, bool useincludepath false, resource context null, int offset 0, int length null ): stringfalse This function is similar to file (), except that filegetcontents () returns the file in a string, starting at the specified offset up to length bytes. The function stops reading after reaching a specified length, encountering a new line or reaching the end of file. $lines += substr_count(fread($f, 8192), "\n") The fgets () function in PHP reads the current line from an open file pointed to by the resource handle.

Method 1: Python count numbers of lines in a string using readlines () The readlines () are used to read all the lines at a single go and then return them as each line a string element in a list. Using a loop of fgets() calls is fine solution and the most straightforward to write, however:Įven though internally the file is read using a buffer of 8192 bytes, your code still has to call that function for each line.
