PHP Read file content several correct methods

method to read with a while to some fgets line
$file _name= "1.txt";

The code is as follows	Copy Code
$FP =fopen ($file _name, ' R '); while (!feof ($FP)) { $buffer =fgets ($fp, 4096); echo $buffer. " <br> "; } Fclose ($FP);

Method two uses file to save to an array at once and then output with foreach

The code is as follows	Copy Code
$array = file ($file); foreach ($array as $v =>$_v) { echo $_v, ' <br/> '; }

Method three uses file_get_contents once to read out

The code is as follows	Copy Code
if (Is_file ($file _name)) { $CN = file_get_contents ($file _name); Echo $CN; }
