preg_replace img tag in sequence in PHP

I have a content, which is like 

Test test test <img src="abc.png" alt='1'> test test <img src="123.png" alt='2'> test test

I would like to change it to be

Test test test <id>1</id> test test <id>2</id> test test

I have tried:

preg_match_all('/<img(.*?)alt=\"(.*?)\"(.*?)>/si', $content, $result, PREG_SET_ORDER);
foreach($result as $val) {                
          $content = preg_replace('/<img(.*?)alt=\"(.*?)\"(.*?)>/si', '<id>'.$val[2].'</id>', $content);

But it gives me:

Test test test <id>2</id> test test <id>2</id> test test

It doesn't seem like preg_match* is the right function to use here, evidenced by the need to loop. It can be accomplished with just a preg_replace():

preg_replace("/<.*? alt=[\"']([0-9]+)[\"'] *>/", '<id>${1}</id>', $teststr);

This will operate on each matched expression independently, and do them all in one shot. If you decide you do need the src value, you can adjust the expression as necessary.

Your replacement inside the foreach contains problem. This is the fixed version.

<?php

$str = <<<term
Test test test <img src="abc.png" alt='1'> test test <img src="123.png" alt='2'> test test'
term;

preg_match_all('/<img.*?alt=[\'"](\d+)[\'"]>/', $str, $matches, PREG_SET_ORDER, 0);

foreach($matches as $val) {                
    $str = preg_replace('/<img.*?alt=[\'"](' . $val[1] . ')[\'"]>/', '<id>'.$val[1].'</id>', $str);
}

var_dump($str);

Try this one.

    $data = `Test test test <img src="abc.png" alt='1'> test test <img src="123.png" alt='2'> test test`;

    $replace = ["<img src='abc.png' alt='1'>","<img src='123.png' alt='2'>"];
    $value = ["<id>1</id>","<id>2</id>"];

    $dataNeeded = str_replace($replace, $value, $emailContent);

echo $dataNeeded;
