alt="title image"

I tried :

$var = str_replace('alt=""', 'alt="'.$title_image.'"', $object);

Answer 1

you can do something like this:

$object='alt=""';
$title_image="test";
$var = str_replace('alt=""', 'alt="'.$title_image.'"', $object); 
echo $var;

Answer 2

Your code should work correctly.

<?php

$object = '<p><img src="/images/blog/023.jpg" alt="" width="910" height="620" data-src="/images/blog/023.jpg" /><img src="/images/blog//wedding-photographer-in-portofino.jpg" alt="" width="910" height="620" data-src="/blog//wedding-photographer-in-portofino.jpg" /></p>';

$title_image = "title image";

echo $var = str_replace('alt=""', 'alt="'.$title_image.'"', $object);

?>

Output

<p><img src="/images/blog/023.jpg" alt="title image" width="910" height="620" data-src="/images/blog/023.jpg" /><img src="/images/blog//wedding-photographer-in-portofino.jpg" alt="title image" width="910" height="620" data-src="/blog//wedding-photographer-in-portofino.jpg" /></p>

Answer 3

We can try str_replace function to solve this problem

 $alt='alt=""' ;
 $var = str_replace("{$alt}", 'alt="title image"',"{$alt}"); 
 echo $var;
