How can I remove part of a string in PHP? [closed]

Question

How can I remove part of a string?

Example string: "REGISTER 11223344 here"

How can I remove "11223344" from the above example string?

Answer 1

If you're specifically targetting "11223344", then use str_replace:

// str_replace($search, $replace, $subject)
echo str_replace("11223344", "","REGISTER 11223344 here");

Answer 2

You can use str_replace(), which is defined as:

str_replace($search, $replace, $subject)

So you could write the code as:

$subject = 'REGISTER 11223344 here' ;
$search = '11223344' ;
$trimmed = str_replace($search, '', $subject) ;
echo $trimmed ;

If you need better matching via regular expressions you can use preg_replace().

Answer 3

Assuming 11223344 is not constant:

$string="REGISTER 11223344 here";
$s = explode(" ", $string);
unset($s[1]);
$s = implode(" ", $s);
print "$s\n";
