PHP caveats – int/float type conversion

The following code checks various scenarios in which inbuilt functions like intval, floatval, is_numeric, is_float and filter_var would result for several different types of values. Feel free to run in your local, leave comments if I can make the results more interesting with some more functions.

How to batch edit multiple images to make square sized pictures with original image in center using php imagejpeg?

<?php
// WORKS FOR JPEG IMAGES ONLY. FOR PNG, change function names

//4. output folder (inside datadir)

//5. force final size -- -- If set to 1/true then line 2 and 3 will become max sizes of output image

How to filter and validate pincode in Indian woocommerce?

By default, Woocommerce only validates ZIP code of few countries only. Woocommerce stores in India, are thus invalidated in case of PINCODE inputs from customers. Here is how you can enable checking of pincode for India woocommerce:

Put the following code in your custom function file or child theme functions.php

add_filter('woocommerce_validate_postcode','validate_indian_postcode',10,3);
function validate_indian_postcode($valid, $postcode, $country){
if($country=="IN")
$valid = (bool) preg_match( '/^([0-9]{6})$/', $postcode );
// checks your $postcode, if valid $valid will be true because of preg_match else false
return $valid;
}

How to reverse the ids in a mysql table column without breaking primary key constraint?

Let me explain the problem scenario: Let us assume we have a table with 4 columns in it out of which 1 is PRIMARY column and rest 3 contain some data.

What we want to do is to reverse the primary key IDs for that data keeping the rest of data intact. It is like shifting the first row to end and moving last row to starting.

Initial Data

idnameemailanything
1jacobwhateverhow to reverse
3nathanwhosoeverisnathanids in mysql table column
4jagmohanidontknowjagmohanwithout breaking
8monicaiamsexyprimary key constraint
9batmanidontexistinrealworldi am batman

Data after update

idnameemailanything
9jacobwhatever how to reverse
8nathanwhosoeverisnathan ids in mysql table column
4jagmohanidontknowjagmohan without breaking
3monicaiamsexy primary key constraint
1batman idontexistinrealworld i am batman

Dude, you are just reversing the column, what is so tough in this?

So, this seems simple to reverse an array if isolated by key “id“. But you have to understand that this column is the primary key. So if you run a command to change id for “jacob” to “9“. It will give you error: “Duplicate entry for id 9

So here is my proposed solution, I start with pair of first and last row and then swap them. Then swap second and second last row. and So on…

If total rows are odd, we will be left with 1 row which does not need correction because it will already be the middle row.

If total rows are even, we would swap middle two rows too.

Here is my solution in PHP

$possible_group_id="3";
$ai=12720; //can be any high int which does not exist in column `id` yet
$q="select id,email from table_name where `possible_group_id`=$possible_group_id order by id asc";
$r=mysqli_query($f,$q);
$row_collection=[];
$ct=[];
while($row=mysqli_fetch_row($r))
{
$row_collection[]=$row;
$ct[]=$row[0];
}
$pt=array_reverse($ct);
$size=count($row_collection);
for($i=0;$i<$size;$i++)
{
$row_collection[$i][2]=$pt[$i];
}
echo "start transaction;<br>";
foreach($row_collection as $k=>$v)
{    
if($k < floor($size/2)){
echo 'UPDATE `table_name` SET `id`='.$ai.' WHERE `email`="'.$row_collection[$size-$k-1][1].'";<br>';
echo 'UPDATE `table_name` SET `id`='.$v[2].' WHERE `email`="'.$v[1].'";<br>';
echo 'UPDATE `table_name` SET `id`='.$row_collection[$k][0].' WHERE `email`="'.$row_collection[$size-$k-1][1].'";<br>';}
else break;
}
echo "commit;<br>";

It would output this:

start transaction;
UPDATE `table_name` SET `id`=12720 WHERE `email`="idontexistinrealworld ";
UPDATE `table_name` SET `id`=9 WHERE `email`="whatever";
UPDATE `table_name` SET `id`=1 WHERE `email`="idontexistinrealworld ";
UPDATE `table_name` SET `id`=12720 WHERE `email`="iamsexy";
UPDATE `table_name` SET `id`=8 WHERE `email`="whosoeverisnathan";
UPDATE `table_name` SET `id`=3 WHERE `email`="iamsexy";
commit;

How to transpose an array in PHP with irregular subarray size?

function transposeCsvData($data)
{
$ct=0;
foreach($data as $key => $val)
{
//echo count($val);
if($ct< count($val))
$ct=count($val);
}
//echo $ct;
$blank=array_fill(0,$ct,array_fill(0,count($data),null));
//print_r($blank);
$retData = array();
foreach ($data as $row => $columns)
{
foreach ($columns as $row2 => $column2) 
{
$retData[$row2][$row] = $column2;
}
}
$final=array();
foreach($retData as $k=>$aval)
{ 
$final[]=array_replace($blank[$k], $aval);
}
return $final;
}

Test Code

$a[]=array("name","john","sam","patrick");
$a[]=array("color","orange","green");
$a[]=array("bikes","suzuki","audi","mercedes","bmw","volks","rover");
$a[]=array("techgiants","samsung","amazon");
print_r(transposeCsvData($a));

Output

How to fix Composer should be invoked via the CLI version of PHP, not the cgi-fcgi SAPI error in SSH?

Put this in your bash profile and run source ~/.bashrc

alias composer="/opt/cpanel/ea-php71/root/usr/bin/php /opt/cpanel/composer/bin/composer"

As Composer is now available via WHM you can use this to find it:

which composer

This returned path “/opt/cpanel/composer/bin/composer” for me. If this returns nothing then disregard the rest of this answer, as Composer is not available to you at system level.

You can now use php-cli to call this with Composer’s absolute path:

php-cli /opt/cpanel/composer/bin/composer install
php-cli /opt/cpanel/composer/bin/composer update
php-cli /opt/cpanel/composer/bin/composer require whatever/example

You may however need to alias php-cli if your system claims this isn’t found. It very much depends how PHP has been deployed on the WHM server. Learn how to fix PHP CLI error. You can do this by adding a user alias to the end of your “.bashrc” or “.bash_profile” file as follows:

alias php-cli=/opt/cpanel/ea-php72/root/usr/bin/php

Replace ea-php72 with the release of PHP you want to use. Submit this as a command in the shell to make it available immediately, otherwise it’ll become available when you open your next Bash session.

If you want to make this available with just composer alone you could create this alias again in “.bashrc”:

alias composer=/opt/cpanel/ea-php72/root/usr/bin/php /opt/cpanel/composer/bin/composer

API Keys

You can get your keys here https://dashboard.paytm.com/next/apikeys

API keys are unique credentials issued to every merchant. While MID is used as an identification used for all exchange correspondence, merchant key is used to encrypt every API request to Paytm and decrypt every response from Paytm. Ensure that you keep the merchant key on server side and should not be shared with anyone. In case API keys are compromised, please reach out to our helpdesk to get new API keys.

  • MID (Merchant ID) – Unique identifier issued to every merchant.
  • Merchant Key – This is a unique secret key used for secure encryption of every request. This needs to be kept on server side and should never be shared with anyone.
  • Industry Type ID – This is part of bank and paymode configuration done wrt to an account.
  • Website – This parameter is used to support multiple callback URLs to post the transaction response. Each URL needs to be mapped to a website parameter.

Test API Details are something like this:

  • Test Merchant ID WArHEFXXXXXXXXXXXXXX <–wont work
  • Test Account Secret Key XXXXXXXXOcv1u7P2 <- wont work
