if function

[mindeekv]

sample.txt:

ass 55 a6 s6aa a666 as as6
 sas a 6  66 6a a666a 66s  a
a  5a55s 555a 55  555s a ssa

And i want make if in sample.txt file is 5a55s, then do one function, if there aren't 5a55s in sample.txt file do another function.

How to do that?

I try something, but its wrong:

$aa = 5a55s

<?php
if (in_array(file('sample.txt'),$aa)){
    header("Location: baigta.php");
}else {
    header("Location: klaida.php");
}
?>

Thanks

You can use [man]file_get_contents/man with [man]strpos/man.

Can you make sample? Using my situation?

A very simple example:

<?php

$filename = 'sample.txt';
$needle = '5a55s';
$haystack = file_get_contents($filename);

if (strpos($haystack, $needle) !== false) {
    function1();
} else {
    function2();
}

?>

Thanks its working, and one more question: how to make that $needle must be 5 symbol number, if $needle is 5a55s its OK, but than its 5a its bad.

i do form and from form i get $needle and i need, that $needle must be 5 charachter and only number.

If you only want to check if it is exactly 5 characters then use [man]strlen/man. If you also need to check that it is a number then use [man]ctype_digit/man as well.

That said, I note that 5a55s is not a number unless you are using letters as numerals.

$filename = 'sample.txt';
$needle = $_POST['needle'];
$haystack = file_get_contents($filename);

if (strpos($haystack, $needle) !== false) {
    function1();
} else {
    function2();
}

Can you make that $needle must be only from numbers and 5 charachters (cant be 4 charachters.....)?

In that case checking with strlen() and ctype_digit() will suffice.

I trying, but its tu hard for me. How to include strlen() and ctype_digit() in this:

$filename = 'sample.txt';
$needle = $_POST['needle'];
$haystack = file_get_contents($filename);

if (ctype_digit($needle)) && (strpos($haystack, $needle) !== false) {
    function1();
} else {
    function2();
}

I would expect something like this:

if (!empty($_POST['needle']) && strlen($_POST['needle']) == 5 && ctype_digit($_POST['needle'])) {
    $filename = 'sample.txt';
    $needle = $_POST['needle'];
    $haystack = file_get_contents($filename);

if (ctype_digit($needle)) && (strpos($haystack, $needle) !== false) {
    function1();
} else {
    function2();
}
}

Thanks its working! And last question how to make, then found, delete that text?

lol Why don't you just ask Laserlight to write your entire site for you...
Look through the links given to you.. try things out.. learn a little more. Nothing wrong with going to forums for some help and guidance, but help / educate yourself as well.

I dont know what function do it.
