替换URL查询字符串与str_replace函数

Question

我有一些网址类似如下的URL：

https://example.com/xyz/jjJAjsjahjsjhUAUiOAkskpAs？ q = 1280wq

https://example.com/xyz/jjJAjsjahjsjhUAUiOAkskpAs？ q = 5080wq

https://example.com/xyz/jjJAjsjahjsjhUAUiOAkskpAs？ q = 860

https://example.com/xyz/jjJAjsjahjsjhUAUiOAkskpAs？ Q = 86058

现在我要替换q值与像589的恒定值，我怎么能在PHP str_replace做呢？

Answer 1

试试这个方法：

$content = "https://mysite.com/xyz/jjJAjsjahjsjhUAUiOAkskpAs?q=1280wq"; 

$content = preg_replace("q=\w+", "", $content); 

Answer 2

$url = 'https://mysite.com/xyz/jjJAjsjahjsjhUAUiOAkskpAs?q=1280wq'; 

$query = parse_url($url, PHP_URL_QUERY); 
parse_str($query); 

echo $q; 

Answer 3

它可以通过str_replace函数就像这样：

<?php 
$myString = 'https://example.com/xyz/jjJAjsjahjsjhUAUiOAkskpAs?q=1280wq'; 
$myNewString = str_replace('?q=', '/589/', $myString); //this line replaces the '?q=' with '/589/' 
echo $myNewString; //OUTPUT: https://example.com/xyz/jjJAjsjahjsjhUAUiOAkskpAs/589/1280wq 
?>
