append in php code example

Example 1: php append to file

// LOCK_EX will prevent anyone else writing to the file at the same time
// PHP_EOL will add linebreak after each line
$txt = "data-to-add";
$myfile = file_put_contents('logs.txt', $txt.PHP_EOL , FILE_APPEND | LOCK_EX);

// Second option is this
$myfile = fopen("logs.txt", "a") or die("Unable to open file!");
$txt = "user id date";
fwrite($myfile, "\n". $txt);
fclose($myfile);

Example 2: php append to array

$myArr = [1, 2, 3, 4];

array_push($myArr, 5, 8);
print_r($myArr); // [1, 2, 3, 4, 5, 8]

$myArr[] = -1;
print_r($myArr); // [1, 2, 3, 4, 5, 8, -1]

<?php
// Insert "blue" and "yellow" to the end of an array:


$a=array("red","green");
array_push($a,"blue","yellow");
