本教程提供了几款php教程 删除字符串中的空格多种方法哦,用了php函数,str_replace,trim,正则等替换字符串的空格有效方法
用php自带的函数
str_replace( " ", " ",$str);
来替换
$str = "##使用函数trim去掉字符串两端特定字符####";
$str1 = trim($str,"#"); //为函数trim传入第二个参数,trim将删除字符串$str两端的#字符
echo $str."
";
echo $str1;
?>
实例
$str = " 使用函数trim去掉字符串两端空白字符 ";
$str1 = trim($str); echo "处理前有".strlen($str)."个字符";
echo "
";
echo "
";
echo "使用trim函数处理后有".strlen($str1)."个字符";
?>
看个高级一点的
php程序删除"数组"中"字符串元素"中的"空格"
$arr=array();
$arr[]="ad dfd dfd";
$arr[]="saf sdf dsf";
$arr[]="sdf dsfgfd dd";
$arr[]="dfd dfferw ";
while(list($name,$value)=each($arr)){
echo $value;
$arr2[]=trim($value);//去空格
}
print_r($arr2);//这应该是你想要的数组吧~
?>
用正则表达试删除空格
$string = preg_replace("/s+([rn$])/", "1", $string);
when "$" is inside [], www.45it.net does not represent the end of string
---------------------------------------------------------------
$string = preg_replace("/s+([x20]|$)/", "1", $string);
---------------------------------------------------------------
$string = preg_replace("/x20+([rn]|$)/", "1", $string);
---------------------------------------------------------------
$string = preg_replace('/([rn])[s]+/', '1', $string);
