This article mainly introduces PHP to replace parameters in url, which has certain reference value. Now I share it with everyone. Friends in need can refer to it
<?php $url=$_SERVER["argv"][0]; $url1=replace_var($url,"page",100); echo $url1; function replace_var($url,$string,$new_value) { while(substr($url,0,1)=="&") { $url=substr($url,1); } if($url!="") { $url_array=explode("&",$url); $new_url=$_SERVER['PHP_SELF']."?"; $string_len=strlen($string)+1; $i=0; while($url_array[$i]) { if(substr($url_array[$i],0,$string_len)==$string."=") { $url_array[$i]=$string."=".$new_value; } if($i>0) $url_array[$i]="&".$url_array[$i]; $new_url=$new_url.$url_array[$i]; $i++; } } else $new_url=$_SERVER['PHP_SELF']; return $new_url; } ?>
