This article introduces the relevant knowledge of "what are the differences between fgetc () and fgets () in php". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Differences: 1. Fgetc () is used to read a character from an open file and return a string containing one character, while fgets () is used to read a line of data from an open file and return a string of specified length. 2. The fgetc () function accepts only one argument, while the fgets () function accepts two arguments.

Operating environment of this tutorial: windows7 system, PHP7.1 version, DELL G3 computer

In php, both fgetc () and fgets () can read data from a file, but there are differences, which are described below.

The difference between php fgetc () and fgets ()

1. Functional differences

Fgetc (): reads a character from an open file

Fgets (): reads a row of data from an open file

2. Grammatical differences

Fgetc (): only one parameter is accepted

Fgetc ($handle)

The parameter $handle is the open file

Fgets (): two parameters are acceptable

Fgets ($handle [, $length])

The parameter $handle is the open file

The parameter $length is optional and is used to set the length of data to be read.

3. The difference of return value

The fgetc () function returns a string containing a character that is obtained from the file pointed to by $handle. Returns FALSE when EOF is encountered.

The fgets () function reads a line from a specified file and returns a string of a specified length. Stop when you encounter a newline character, EOF, or read the $length-1 byte. If the $length parameter is omitted, the length of 1k (1024 bytes) is read by default.

Expand knowledge:

We have a text file called "test.txt" that contains:

Use fgetc () to read the file character by character

Use fgets () to read the file line by line
