The string comparison can be easily done by the PHP built-in function called strpos(). The strpos() function in PHP, is the easiest way to check if a string contains a specific word or substring. The strpos() function finds the position of the first occurrence of a substring in a string. It returns the position if the string is found, otherwise returns FALSE.
Using the strpos() function, you can check if a string contains a specific word or character, or substring in PHP.
The following example code snippet checks whether a specific word exists in the given string.
$string = "Welcome to codexworld, the world of programming.";
$word = "codexworld";
if(strpos($string, $word) !== false){
echo "The word '$word' was found in the given string";
}else{
echo "The word '$word' was not found in the given string";
}
The following example code snippet checks whether a specific substring exists in the given string.
<?php
$string = "Welcome to codexworld, the world of programming.";
$substring = "the world";
if(strpos($string, $substring) !== false){
echo "The substring '$substring' was found in the given string";
}else{
echo "The substring '$substring' was not found in the given string";
}
The strpos() function is case-sensitive, use the stripos() function for case-insensitive comparison in PHP.
