Kiss is a feature in software engineering which lot of us talk and lot of us try to follow too.

I was just trying to write a function which could remove a specified character from the begining of a string and I came up with two functions. The first one spans 20 lines and it uses a preg_split(), array_pop(), implode(), strlen() and 2 times array_reverse() and a for loop and an if else block. With all these you can expect the complexity of the function.

But the second one takes a single while and substr() function. Isnt it greate that a human mind thinks in two entire directions within a span of 1 hr. I think it is just the mood that we are in decides the way we program.

Here are the functions for your reference.


function format_int($val, $pop_what)
{
$val_len = strlen($val);
$tmp_val = $val; //performing the logic on a tmp vlue as just in case if the real value is needed
$tmp_val = preg_split('//', $tmp_val, -1, PREG_SPLIT_NO_EMPTY); //converting string into array
for($i = 0; $i < $val_len; $i++)
{
if($tmp_val[0] == $pop_what)
{
$tmp_val = array_reverse($tmp_val);
array_pop($tmp_val);
$tmp_val = array_reverse($tmp_val);
}
else
{
break;
}
}

return implode("",$tmp_val);
}

function format_int_smart($val, $pop_what)
{
while( $val[0] == $pop_what )
{
$val = substr( $val, 1);
}
return $val;
}

Usage:
format_int("00010","0"); //return 10
format_int_smart("00010","0"); //returns 10

How to Know whether Email Sent or Not Using PHP

I was wondering since a long time on how to know whether email sent via PHP's mial() function reached or not. You can do it using error_log() function. Following is a syntax

mail('to', 'subject', 'message', 'headers') or error_log("Email didn't make it to receipient (insert email address variable here)", 1 , "email_address@to_send_to");

The 2nd argument "1" tells error_log to send the error to the email address provided in the next argument "email_address@to_send_to"

Just for your reference following is a way to validate an email address using regular expressions

function is_valid_email($email)
{
if(preg_match("/[a-zA-Z0-9_-.+]+@[a-zA-Z0-9-]+.[a-zA-Z]+/", $email) > 0) {
return true;
}
else {
return false;
}
}

Problems Reading PHP Arrays Using each()

When you read PHP arrays using each(); the array cursor will be left on the next element of the array, or past the last element if it hits the end of the array. You have to use reset() if you want to traverse the array again.

Country list with ISA/ISB Codes

This function will take in a country ISA/ISB code and translate it into full country name. It includes a downloadable SQL file (below)

Link to the downloadable SQL file :http://www.phptricks.com/get_file.php?file_name=country_list.zip&t=2

<?php

//This function takes in a country code "US/GB/.." and returns
//Full country name
//This uses a database to get the name

function get_name($code) {
$reterieve_country = @mysql_fetch_array(@mysql_query("SELECT * FROM countrylist WHERE `lsa`= '$code' OR `lsb`= '$code'"));
if($reterieve_country[1] == NULL){
$country_name = 'Other';
} else {
$country_name = $reterieve_country[1];
}
}
?>

Page numbering from MYSQL data

This will number your pages with the Previous 1 2 3 4 Next sequence.

<?php

//Start out by writing your query(general)
$get_items = "SELECT * FROM `items`";

//How many items to display per page?
$display_limit = '10';

//We need to see how many items are there in the first place
$items_count = @mysql_num_rows(@mysql_query($get_items));

//Are we getting the page count from url or making a new one?
if(isset($_GET['page_count'])) {
$page_count = $_GET['page_count'];
} else {
if($items_count > $display) {
$page_count = ceil ($items_count/$display_limit);
} else {
$page_count = 1;
}
}

//Where are we going to start from?
if(isset($_GET['start'])){
$start = $_GET['start'];
} else {
$start = 0;
}

//Now make the final query (the one we actually using)
$get_items_query = @mysql_query($get_items . " LIMIT $start,$display_limit");

//To display the numbering anywhere under the page use this code//
if($items_count > $display_limit){
$current_page = ($start/$display_limit)+1;
//Do we need to print previous?
if($current_page != 1) {
echo '<a href="index.php?&start=' . ($start-$display_limit) . '&page_count=' . $page_count . '">Previous</a>';
}
//Print out the numbers
for ($i = 1; $i <= $page_count ; $i++) {
if($i != $current_page){
echo ' [<a href="index.php?&start=' . (($display_limit * ($i - 1))) . '&page_count=' . $page_count .'">' . $i . '</a>] ';
} else {
echo '<font color="gray"> [' . $i . '] </font>';
}
}
//Print out Next
if($current_page != $page_count){
echo '<a href="index.php?&start=' . ($start+$display_limit) . '&page_count=' . $page_count . '">Next</a>';
}
}

/* To display the items, you use whatever you want, for our case simply print every item */
while($each_item = @mysql_fetch_array($get_items_query)){
echo $each_item['item_title'];
}
?>

Checking for a user country via Database

This function (which includes database-download from link below), will be able to check for the user's country.

Link for database(zip file): http://www.phptricks.com/get_file.php?file_name=phpskills.com.zip&t=2

<?php
//Function to check for user country
function check_country($ip){
$ip = sprintf("%u", ip2long($ip));
$country = 'other';

$check_country = @mysql_query("SELECT `country`,`a2`,`a3`,`number` FROM `country_ip_list` WHERE `ipfrom` <= '$ip' and `ipto` >= '$ip' LIMIT 0, 1");

if($get_country = @mysql_fetch_row($check_country)){
$country = $get_country[0];
}
return $country;
}

//Sample implementation
$user_country = check_country($_SERVER['REMOTE_ADDR']);
echo "You are from: $user_country";
?>
