PHP multiple replacements

Question

I have got multidimensional array (name + image path), where some names are similar, like:

array("name" => "OpenGL", "img" => "OpenGL.png"),
array("name" => "OpenGL Lighting ( Advanced )", "img" => "OpenGL-LightingAdvanced.png")

then I replace names with images.

foreach ($extensions as $extension) {
    $ret=str_ireplace($extension['name'],'<img src="images/'.$extension['img'].'" alt="'.$extension['name'].'" />: ',$ret);
}

It works as long as array is sorted from shortest name to longest one, but in that case, longer names will never be changed, eg. OpenGL Lighting ( Advanced ) will be

<img src="images/OpenGL.png" alt="OpenGL" /></div>:  Lighting ( Advanced )

When I sort it from longes name to shortest one it is even worse, couse it will change name in src:

<img src="images/<img src="images/OpenGL.png" alt="OpenGL" />: -LightingAdvanced.png" alt="<img src="images/OpenGL.png" alt="OpenGL" />:  Lighting ( Advanced )" />:

My only idea is to check if there isn't src="images/ or alt=" before name, if so - replace, but I have no idea how can I easily do.

You could always just add the quotes to the replace, delimiting it! — adeneo

Something like str_ireplace($extension['name']." "? Sadly I can't do so :( — Andy

Maybe sprintf will work:

foreach ( $extensions as $extension ) {
    $ret = sprintf( '<img src="images/%s" alt="%s" />: ', htmlspecialchars( $extension['img'] ), htmlspecialchars( $extension['name'] ) );
}

You'll need htmlspecialchars() for the string arguments to ensure correct html output...

100% true, post updated to htmlspecialchars( $extension['img'] )

Maybe nooby, but I don't see how I can quickly use sprintf. $ret contains string like "bla bla OpenGL bla bla OpenGL Lighting ( Advanced ) bla" and I want to change that names into images...

You don't need the foreach loop around str_ireplace(), just use it like this:

$ret=str_ireplace($array_of_all_search_words, $array_of_all_replacement_words, $ret);

and it won't replace anything it has already replaced. You might still have to sort the search words by length, though.

Somebody mentioned strtr().

Very helpful but case-sensetive and I need case-insensitive function.
Luckily somebody wrote case-insensitive function stritr() in the comments.
