php循环遍历textarea中的每个字符串行
我使用此脚本从数组中的textarea获取每一行:php循环遍历textarea中的每个字符串行,php,foreach,explode,Php,Foreach,Explode,我使用此脚本从数组中的textarea获取每一行: //trim off excess whitespace off the whole $text = trim(get_field('backlinks')); //explode all separate lines into an array $textAr = explode("\n", $text); //trim all lines contained in the array. $textAr = array_filter($t
//trim off excess whitespace off the whole
$text = trim(get_field('backlinks'));
//explode all separate lines into an array
$textAr = explode("\n", $text);
//trim all lines contained in the array.
$textAr = array_filter($textAr, 'trim');
//loop through the lines
var_dump($textAr);
foreach ($textAr as $line) {
echo $line;
}
我的var_dump输出是:
echo$行的html输出;是:
我的var_dump的输出为:
我不希望输出/回音中出现换行。我做错了什么
提前感谢尝试使用impload
回波内爆,$textAr 尝试使用内装
回波内爆,$textAr 对不起,我想这是PHP代码,这是我文本区域的一个设置,它的广告是
在每一行之后。对不起,我认为这是PHP代码,它是我文本区域的一个设置,在那里它的广告
//trim off excess whitespace off the whole
$text = trim(get_field('backlinks'));
//explode all separate lines into an array
$textAr = explode("\n", $text);
//trim all lines contained in the array.
$textAr = array_filter($textAr, 'trim');
//loop through the lines
var_dump($textAr);
foreach($textAr as $line) {
echo str_replace("\n","",str_replace("\r","",$line));
}
每行后面。在$text变量中有什么?这里似乎有一些br标记,您可能没有考虑到换行符可以由多个单独的\n表示,但也可以有一个额外的\r标记。或者在某些[旧]系统上只有一个\r。在$text变量中有什么?这里似乎有一些br标记,您可能没有考虑到换行符可以由多个单独的\n表示,但也可以有一个额外的\r标记。或仅在某些[旧]系统上\r。
