PHP - Is An Int With A Length Of 3 Different Than A Tinyint With A Length Of 3?

For PHP 7.4, what is the recommended session length that I should be using to have the best security?

In DEV< in my php.ini file, session.sid_length = 26

According to the comments above that, it sounds like you can go up to 256.

Is it fair to assume that larger is more secure?

Also, if I set it to a larger size like 256, is tehre any risk of breaking things on my (VPS) web server running WHM/cPanel?

Hello everyone,

I've searched these forums for a while now trying to resolve a problem that I have with my sessions timing out before I would like them to, but I've only gotten confused about it.  I've read about changing some settings or adding code in my php.ini file but I have no idea what I'm doing when it comes to that.  I'm starting the session simply by having session_start(); at the top of each of my pages.  I'm including a copy of my entire php.ini file here so that you can see what I have already.  Can someone please help me to figure out what I would need to do to make my sessions last at least 8 hours?  Thanks in advance.

Here's my php.ini file:
Code: [Select]
register_globals = off
allow_url_fopen = off

expose_php = Off
max_input_time = 60
variables_order = "EGPCS"
extension_dir = ./
upload_tmp_dir = /tmp
precision = 12
SMTP = relay-hosting.secureserver.net
url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=,fieldset="

Hey there, need some help badly.

I'm trying to get the size of the BLOB data in mysql. Did a search and there are like no tutorial on this. Only relevant info was from this page, at the far bottom, it just wrote this (below code). But the writer did not explain how to use it.

SELECT OCTET_LENGTH(content) FROM BloBTest WHERE filename='myimage.png'

I just give it a trial an error, wrote this, but did not work.

$LENGTH = mysql_query("SELECT OCTET_LENGTH(blobdata) FROM thedatabase WHERE id = 'selected_id'");
echo $LENGTH;

Please help....

Hi    I am running on Linux scripts with PHP and need help with separating my output on html screen to have different sections. This is my php info below   echo "<td bgcolor=\"#00B400\"><a href="$f3"><font size="2">$f1</font></td>" >> $PINGVAIL

im trying to update a GPS table
for example:
UPDATE markers SET lat = '38.40907441955112' AND lng = '14.943452775478363' WHERE ApID = '35911'
i tried with float 20,18 it isnt updatng correctly 

When a user logs on, I authenticate them with a session.  How do I use php to determine the time until the session will expire?  I realize I could go into the ini file but is there a php code that can query this info and echo it back?

I am trying to figure out a way of filtering certain words from a string using str_replace - However i would like to replace the words with something showing the correct length of the word.

So far I have got:

Code: [Select]
<?php

$input = "Oranges, apples, and pears are all types of fruit!";
$words = array("oranges","apples","pears");

function convertType($x) {
$maskWords = array();
$convertChar = "*";
for ($i = 0; $i < strlen($x); $i++) {
array_push($maskWords, $convertChar);
}
$convertString = implode(".", $maskWords);
$stripString = str_replace(".", "", $convertString);
return $stripString;
}

for ($i = 0; $i < count($words); $i++) {
$input = str_ireplace($words[$i], convertType($words[$i]), $input);
}

print $input;

?>
As I am fairly new to PHP I am not sure if this is the most effiicent way of doing this so I was hoping somebody could provide some input for me. For instance is there a function to convert the array into a full-length string without using a delimiter?

Thanks!

This isn't for anything practical, I'm just fiddling. Anyways, I'm wondering if there's anyway to make this more efficient since at higher lengths it could become really heavy. $l is length of the number.

function fixed_random($l) {
$number = "";
do {
$r = mt_rand(0, $l);
$number .= $r;
} while (strlen($number) < $l);
return $number;
}

Hi all,

Yesterday I moved a web application from a normal cookie session to a use_trans_sid session because some users' browser didn't accept cookies.

This works great, but the session used to last for 45 minutes (set with session.gc_maxlifetime), but after the change the session times out faster.

(How) can I set the session length if I use use_trans_sid?

Thanks,

Base

PS: PHP version 5.2.13-1

I have an integer that I'd like to validate to ensure that it is a valid number between 1 and 99999999999999999999(20 digits).

I'm thinking about using the following, but I'm not sure what the max range is on the FILTER_VALIDATE_INT options.

return filter_var($_REQUEST['r'], FILTER_VALIDATE_INT, array("options" => array("min_range"=>1, "max_range"=>99999999999999999999)));

How can I test if a chunk exceeds the image size and wrap that text to the next line. Not sure if I am even doing this correctly with my if statement.

    $text="Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem http://somelongurl.com/then-we-make-it-super-long-with-some-more/ Lorem Ipsum Lorem Ipsum Lorem Ipsum http://www.anotherlinks.com/";
    
    $string_chunks = explode(' ', $text);
    
    foreach ($string_chunks as $chunk) {
    
        if($end_x + $chunk > $image_width){
            $start_x = 5;
            $start_y += 20;
        }
    
       $coords = imagettfbbox($fontsize, $angle, $font, $chunk);
    
       $end_x = $coords[0] + $coords[4] + 10;
    
       $color_to_draw = is_a_url($chunk) ? $linkcolor : $black; 
    
       imagettftext($im, $fontsize, $angle, $start_x, $start_y, $color_to_draw, $font, $chunk);
    
       $start_x += $end_x;
    }
With this code I get:

Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem 
http://somelongurl.com/then-we-make-it-super-long-with-some-more/
Lorem Ipsum Lorem Ipsum Lorem Ipsum http://www.anotherlinks.com/


What I would like to happen is something like:
 
Lorem Ipsum Lorem Ipsum Lorem Ipsum 
Lorem http://somelongurl.com/then-we
-make-it-super-long-with-some-more/
Lorem Ipsum Lorem Ipsum Lorem Ipsum

Is there any limit to the length of an array element in a flat data file?

For instance, I have a flat file that I might end up having 200 rows, with each row containing 15 elements.  Most of the elements will be about 20 characters or less, but a couple of the elements might be 300-400 characters.

I'm guessing there is no limit.

And since each row will be longer than one "line" in a .txt file, how best to mark the end of a row?

[I assume that using a database is probably the better way to do this, but on this particular website I'm working on that isn't an option.]

I have a string in the form of "word1-word2-word3-word4-word5-word-6-word7", but I want to shorten it to 5 words only. 

Hi,
I have a Flash contact form that sends its name, e-mail, and message variables to a PHP script. The script works fine if the message is under ~700 characters, but anything more and the script won't post the message at all. An e-mail with just the name and e-mail address will come through to my inbox (which is embarrassing as a potential client sent me a contact form e-mail about a development job  ).

Is there some way to check the maximum character length for a string variable? Or to set its length to something higher?

This is my php. Thank you!!
