Closing file in php is all related to fclose( )<\/span><\/code> Function. With the help of this code we can run closing function in php.<\/p>\n\n\n\n

What is fclose( ) Function in php?<\/h3>\n\n\n\n

In PHP, the fclose()<\/strong><\/span><\/code> method is used to close a file referenced by an open file pointer. If the method fclose()<\/strong><\/span><\/code> is successful, it returns true; otherwise, it returns false. It accepts the file that needs to be closed as an input and closes it.<\/p>\n\n\n\n

Syntax:<\/strong><\/p>\n\n\n\n

bool fclose( $file )<\/strong><\/span><\/code><\/pre>\n\n\n\n
Parameters:<\/strong><\/p>\n\n\n\n
The $file argument is the only one accepted by PHP’s fclose()<\/strong><\/span><\/code> function. The file that has to be closed is specified by this argument.<\/p>\n\n\n\n
Return Value:<\/strong><\/p>\n\n\n\n
If it succeeds, it returns true; if it fails, it returns false.<\/p>\n\n\n\n
Errors And Exception<\/strong>:<\/p>\n\n\n\n
  • If you want to read the contents of a file that was written using the fwrite()<\/strong><\/span><\/code> function, you must first shut it with the fclose()<\/strong><\/span><\/code> function.<\/li>
  • For remote files, PHP’s fclose() method does not work. It only works with files that the server’s filesystem can access.<\/li><\/ul>\n\n\n\n
    Let’s take examples to explain this function:<\/strong><\/p>\n\n\n\n
    Input : $check = fopen(\"gfg.txt\", \"r\");\r\n        fclose($check);\r\nOutput : true\r\n\r\nInput: $check = fopen(\"singleline.txt\", \"r\");\r\n       $seq = fgets($check);\r\n       while(! feof($check))\r\n       {\r\n         echo $seq ;\r\n         $seq = fgets($check);\r\n       }\r\n       fclose($check);\r\nOutput:true<\/code><\/pre>\n\n\n\n
