Problem:
You have a string. You want to check if that string ends with another string or a character.
Solution:
PHP has a built-in funcation named substr_compare() which is used to compare two strings. We’ll use this function to compare if a string or a character ends with another string. See the example below-
[php]
<?php
$string = "Learn web development from SchoolsofWeb.com";
$subString = "SchoolsofWeb.com";
$result = substr_compare($string, $subString, -16, 16);
echo ($result === 0)? "Yes, the string \"$string\" ends with \"$subString\" ": "No, the string \"$string\" doesn’t end with \"$subString\"";
?>
[/php]
[wpdm_file id=121]
Output:
Yes, the string “Learn web development from SchoolsofWeb.com” ends with “SchoolsofWeb.com”.
How it works:
| Line 2 | The main string |
| Line 3 | The substring to be compared with. It has 16 characters. |
| Line 4 | The substr_compare() function finds if $subString(second parameter) starts from the last 16 characters(the negative sign in the third parameters asks to compare from the end) of the $string string(first parameter) and ends after 16 character(fourth parameter which is the length of the $subString). If the function finds the matches, it returns 0 and we store it in $return variable. |
| Line 5 | If the $return variable is equal to 0, then we print the first success message, else the next one. |
Nice post. I was looking to see if PHP had some sort of an ends_with function, but this works just as well, since it can be done in a single line. Thanks!
