How to Check if a String Begins with Another String in PHP?

Problem:

You have a string. You want to check if that string starts with another string or a character.

Solution:

Using strops() function, you can find the first occurrence of a string inside another string. The strpos() function finds the position of the first occurrence of a string/character in another string. See the example below-

<?php
$haystack = "HTML is the language of web.";
$needle = "HTML";
echo strpos($haystack, $needle, 0)=== 0 ? "Yes, the string begins with $needle.": "No, the string doesn't begin with $needle.";
?>

[wpdm_file id=110]

Output:
Yes, the string begins with HTML.

Line 2	This is the string we’ll serach into
Line 3	This(HTML) is the string that we’ll find.
Line 4	The strops() function will search the $needle(HTML) in the $haystack. The function founds the $needle in the first position and returns 0, so the ternary operator prints “Yes, the string begins with HTML. ”.

Notes

We used identical operator(===) to make sure that the $needle exists at the beginning of the $haystack. Not only the condition above won’t return 0 if the $needle is existed in other positions other than the first one, but also, If the function return false if the $needle is not existed in the $haystack. But, the identical operator(===) will ensure the $needle is in the beginning of the $haystack.
