chop string function to remove blank space line break etc from right side of the string in PHP

chop() : remove string from right end

$string='Welcome to plus2net.com';
echo chop($string,'.com');

output

Welcome to plus2net

WE can remove white space at the end of the string .

echo chop("welcome to plus2net  ");

Output

welcome to plus2net

To indentify the removal of white space we will add one more string and check like this.

$str="Welcome to plus2net  ";
//echo $str;
echo chop($str);
echo "Thanks";

The output is here

Welcome to plus2netThanks

In the above code we can check the difference by un-commenting 2nd line and adding the comment to third line. We will see the gap before the word Thanks

Welcome to plus2net Thanks

Other than white space we can also remove these .

"\0"-ASCII 0, null
"\t" Tab
"\r" carriage return
"\n" new line
"\x0B" vertical tab
" " white space

Example: Chopping Specific Characters

$str = "Hello World!!!";
echo chop($str, "!");  // Output: "Hello World"

Example: Chopping Multiple Characters

$str = "abcdefxyz";
echo chop($str, "xyz");  // Output: "abcdef"

Example: Removing Trailing Numbers

$str = "Data123";
echo chop($str, "123");  // Output: "Data"

Example: Removing Multiple Characters from the End

$str = "Hello!!!???";
echo chop($str, "!?");  // Output: "Hello"

Example: No Effect if Character Not Present

$str = "Hello World";
echo chop($str, "?");  // Output: "Hello World" (No effect as '?' is not present)
