Change specific value in PHP variable

Question

I have a variable $var and it contain comma separated value.

$var = 'the_ring,hangover,wonder_woman';

I want to make it like below.

$var = 'The Ring,Hangover,Wonder Woman';

I tried $parts = explode(',', $var); also I tried strpos() and stripos() but not able to figure it out.

What can I do to achieve this?

Is there a reason you're using a string rather than an array? — blackandorangecat

@Fred-ii- These are movie titles, which would be Camel Case :) — blackandorangecat

$var = 'the_ring,hangover,wonder_woman';

$list = explode(',', $var);

$list = array_map( function($name){
    return ucwords(str_replace('_',' ', $name));
}, $list);

Returns:

Array
(
    [0] => The Ring
    [1] => Hangover
    [2] => Wonder Woman
)

Imploding:

$imploded = implode(',', $list);

Returns:

'The Ring,Hangover,Wonder Woman'

Man, Why do you have to write too many lines of code to achieve something, which can be done with few lines of code?

You can use array_walk to do your replace and uppercase:

$var = 'the_ring,hangover,wonder_woman';

$parts = explode(',', $var);

array_walk($parts, function(&$item){
    $item = str_replace('_', ' ', $item);
    $item = ucwords($item);
});

$var = implode(',', $parts);

This only makes the first word upper case - FYI

This is how you replace _ with white spaces using str_replace() function

$var = 'the_ring,hangover,wonder_woman';
echo str_replace("_"," ",$var);

$var = 'the_ring,hangover,wonder_woman';
$var1 = explode(',' $var);

foreach ($var1 as $key => $value) {
   $var1[$key]=str_replace("_"," ",$value);
   $var1[$key]=ucwords($var1[$key]);
}

$var = implode(',', $var1);

1.use str_replace to replace something in the string. In your case _ is replaced with space 2.use ucFirst method to capitalize every first character in the strings

$replaced = str_replace('_', ' ', $var);
$changed = ucfirst($replaced);
