本文介绍了一个PHP自定义函数trimall(),用于去除字符串中的各种空白字符,包括常规空格、制表符、换行符和回车符等。该函数通过str_replace方法实现,提供了一种简单有效的方式清理文本数据。
public function trimall($str){//删除空格
$qian=array(" "," ","\t","\n","\r");
$hou=array("","","","","");
return str_replace($qian,$hou,$str);
$qian=array(" "," ","\t","\n","\r");
$hou=array("","","","","");
return str_replace($qian,$hou,$str);
}
