How to Remove Space from String in PHP

There are couple of ways to the answer of  “How to remove Space from String in PHP ”  or replace the space of a sting with something else in PHP.  There are plenty of functions like.

  • str_replace
  • trim
  • ltrim
  • rtrim
  • explode – implode

But all the above function can not be used on the same string for getting the same result,every function has some condition in which that would be good to use that.

For example:-

$str = ” sam”;

above string the left space so we can remove that with :-ltrim()

echo ltrim($str); // sam

if string is :-

$str = “sam “; than rtrim() will be used

echo rtrim($str); //  sam

And if we have string like :-

example: 1

$str = “Ram is a good boy”;

echo str_replace(‘ ‘,’-‘,$str); //

output : – Ram-is-a-good-boy

Let take a example 2:-


$String = “India is Good”;  // let we have a string

we wants to replace Good with Great.

$new_string = str_replace(‘Good’,’Great’,$String);

echo $new_string; // output India is Great


And lastly we have a another option to achieve the above functionality of replacing a string  by explode() than implode() function


$str = “Ram is a good boy”;

Now convert the string into array by explode(separator,string,optional);

$new_array = explode(‘ ‘,$str);

now $new_array is like $new_array(‘Ram’,’is’,’a’,’good’,’boy’);

Now convert the above array back into string with implode(separator,array)

echo implode(‘-‘,$new_array);

output : – Ram-is-a-good-boy
