1. 使用 stripos
函數來檢查字符串是否以某個字符串開頭:
<?php
$string = "Hello world";
$needle = "Hello";
if (stripos($string, $needle) === 0) {
echo $string . " starts with " . $needle;
} else {
echo $string . " does not start with " . $needle;
}
// Output:
// Hello world starts with Hello
?>
2. 使用 stripos
函數來檢查字符串是否以某個字符串結尾:
<?php
$string = "Hello world";
$needle = "world";
if (stripos($string, $needle) === strlen($string) - strlen($needle)) {
echo $string . " ends with " . $needle;
} else {
echo $string . " does not end with " . $needle;
}
// Output:
// Hello world ends with world
?>
這些示例只是 stripos
函數的一部分高級用法,實際上,該函數還具有很多其他功能,您可以根據需要進一步學習和了解。希望本篇文章對您有所幫助。
