Php 检查字符串中的字符

我想看看字符串profile.php是以结尾还是最后4个字符等于.php

如何使用PHP实现这一点

谢谢

用于获取最后4个字符，然后将其与string.php进行比较

您可以尝试PHP的内置函数

这在PHP中非常容易。请参阅。RTLM：可能的副本

if (substr("profile.php", -4) === ".php")
{
    echo "Ends in .php";
}
else
{
    echo "Doesn't end in .php";
}

<?php
$path_parts = pathinfo('/www/htdocs/inc/lib.inc.php');
echo $path_parts['dirname'], "\n";
echo $path_parts['basename'], "\n";
echo $path_parts['extension'], "\n"; // return php
echo $path_parts['filename'], "\n";
?>
