What is "stripos"?

<?php

// https://www.php.net/stripos

// Find the position of the first occurrence of a case-insensitive substring in a string

// PHP could have a function called "contains"

stripos('hello world', 'o')   // position 4
stripos('hello world', 'wor') // position 6
stripos('hello world', 'hel') // position 0
stripos('hello world', 'aaa') // position "false"

// "Contains" concept
stripos('hello world 123 magento', 'world') !== false // position 6

?>


-----------------------------------------------


1) Try to track directly into the concrete object

vendor/magento/module-catalog/Model/Category.php

->setName  or  ->setDescription


-----------------------------------------------


2) Try to track on the parent classes

->setData (parent classes)

- vendor/magento/framework/Model/AbstractModel.php
- vendor/magento/framework/DataObject.php

<?php

// first try : vendor/magento/framework/Model/AbstractModel.php
// second try: vendor/magento/framework/DataObject.php

if (is_scalar($key)) {
    $breakpoint = null; // is_scalar($value) && stripos($value, 'montana') !== false
} else if (is_array($key)) {
    foreach ($key as $k => $v) {
        $breakpoint = null; // is_scalar($v) && stripos($v, 'montana') !== false
    }
}

?>

Real World examples:

Example 01 | Who is setting filter "LumaTech"?
Example 02 | Who is setting product price "56.99"?
Example 03 | Who is setting product configurable option as "Yellow"?
Example 04 | Who is setting the "reviews"?


-----------------------------------------------

<?php

// first form: array

$object->setData([
    'entity_id' => 9999,
    'name'      => 'xdebug is awesome',
    'title'     => 'you should use it!',
]);


// second form: key + value

$object->setData('entity_id', 9999);
$object->setData('name', 'xdebug is awesome');
$object->setData('title', 'you should use it!');
