How to use function file_get_contents?

[Gajendra1]

Hello,
Could you tell me how one uses the function file_get_contents. According to the documentation, this function reads an entire file into a string, it means that all character strings in the file are stored in a variable? I find it hard to understand. Moreover when one reads an entire file, we must first make an fopen on the file or not? How do I use fopen file_get_contents? Any more discussion on this topic will interest.

See if this code can help you

<Php
$ fl = fopen(fl.php, w +), / / was opening my php fl
$ test = file_get_contents($ fl); / / I read all the character of the fl
echo $ test; / / I display all the contents of the fl
fclose($ fl);
?>

Could you tell me why my preg_replace does not work.
PHP - Selecting
$ temp = file_get_contents('exm.php');
$ temp = preg_replace('# ^ $ # test', 'some', $ temp);
echo $ temp;

The file contains exm three lines:
Other - Select

<p> Hello World </ p> 
<p> Good </ p> 
<p> Bye </ p>

Could you please explain me this?

Here is the code you are looking for

     $ temp = file_get_contents('temp.php');
                $ temp = preg_replace('# ^ $ # blah', 'kikou', $ temp),
                $ ctr=stripslashes($ temp) ; 
                fwrite($ fl, $ ctr); 
                fclose($ fl) ; / / We close the fl * /
                echo 'Editing done successfully' ;

file_get_contents returns only the contents of a file, this is not a resource. Set (I think)
(And it is slower than fopen and other )

[janysek]

Function reads the entire file contents into a string. This is the best way to read the contents of a file. This method is preferred by developers because it uses less memory because of the use of memory mapping techniques.

This is not a pointer to a file open .

$ Handle = fopen ('doc.txt', 'r');

Is not equal to:

$ Content = file_get_contents ('doc.txt');

file_get_contents () returns the CONTENT of the file, fopen () returns him something that serves to open the file. Basically, when you write file_get_contents () is as if you did fopen (), fread () (or fgets ()), fclose. You understand ?
