Replace spaces in a string with '+'

Given a string, How do I change all spaces in that string to a plus sign (+)?
psuedo code:
i.e. IF (char == space) THEN char = '+'

I need to cycle through an array and replace the spaces in a string with a plus sign (+).

	for($j=1; $j<=20; $j++){
                ...
		???... $arr[0][$j]  ...????  //<--This array holds the strings.
                ...
	}

Code (markup):

 

If its of any use, you can do it with implode

$string = this is a string of text;

$NewString = implode('+',$string);

result will be this+is+a+string+of+text

 

foreach ($args as $arg){
$result = preg_replace('/\s/', '+', $arg);
}

 

try after the loop
make str replace

 

basically...

foreach($yourArray as $array)
{
$yourString = str_replace(" ","+", $array['string']
}

 

yes, i think this will solve the problem ... or u can use second solution by unitechy, using preg_replace and space regex is /\s/

regards

 

If the string doesn't contain anything other than alphanumeric characters, hyphens, underscores, and spaces, then the urlencode function should work. Probably easiest to stick with str_replace, but urlencode is still nice to know about.

 

Nice tip joebert. I guess it's obvious what sort of thing I'm working on.

 

echo str_replace(" ","+","Hello in this world");

 

foreach($array as &$value)
{
      $value = str_replace(" ","+", $value);
}

PHP:

either do it like that or use the urlencode() function on $value instead. If using urlencode you could also just use the array_map on the whole array in one line

$array = array_map('urlencode', $array);

Thanks Jay, I'm still getting used to php syntax and the foreach loop.

 

For something involving an array loop to everything, I'd personally use this:

/**
* remove_item()
* Removes an item from the input and returns it.
*/

function remove_item(&$input, $remove)
{
	# Search through the $input for $remove, then replace it with nothing.
	$input = str_replace($remove, '', $input);
}

# Essentially walks through each array item and runs the function with a "space" parameter for
#   the $remove option in the function.
array_walk($array, 'remove_item', ' ');
