str_replace help needed.

hello,

i am trying to replace

alt="Image"

with

alt="<?=$row['title'];?>

(there is space at the beginning and at the end of them)

how can i do this? i am tried different ways but it did not work.

$fullpageweb = str_replace(' alt="Image" ', ' alt="<?=$row['title'];?>" ', $fullpageweb);

PHP:

thanks

 

If you already have the $row array, then do it like this;

$fullpageweb = str_replace(' alt="Image" ', ' alt=' . $row['title'] . ' ', $fullpageweb);

PHP:

If you use single quotes ( ' ' ) then PHP will not parse the string and will just dump whatever is inside them, if you use double quotes ( " " ) then PHP WILL parse the string and swap variables etc. In your case the variable was inside single quotes so PHP did not look for variables etc to replace, I just took the variable out of the string.

Thank you for your help.

instead of . $row['title'] . i have to use <?=$row['title'];?>

is there anyway i can do that?

thanks

 

Well the <? and ?> is usualess as it is already in a php function so is not necessary

 

the whole thing is already covered by <?php start tags

So, you do not have to open <? anymore

 

i am still learning....

i wanted to use this <?=$row['title'];?> thinking i could use it at the output. i did not realize i can change it at the code before output.

now.. i can not use

$fullpageweb = str_replace(' alt="Image" ', ' alt=' . $row['title'] . ' ', $fullpageweb);

PHP:

instead i need to use

$fullpageweb = str_replace(' alt="Image" ', ' alt=" . $title . ", $fullpageweb);

PHP:

but it does not work either.

thanks

 

$fullpageweb = str_replace(' alt="Image" ', ' alt=" '. $title .' " ', $fullpageweb);

PHP:

That should work

 

Yes that should work. You missed the double quotes "

 

it did not work.

i tried the same code with preg_replace and it did not work either.

 

This is how I would originally do it in my scripts:

$fullpageweb = str_replace("alt=\"Image\"", "alt=\"$title\"", $fullpageweb);

PHP:

You can also try str_ireplace

That replaces strings regardles of case
