[英]preg_grep does not show result with double quotes(")
我的代碼如下:
$escapedOperator = ":";
$operator['symbol'] = ":";
$string = 'title: "space before" and text breaks';
if(count(preg_grep('/\w["]*\s*'.$escapedOperator.'\s*["]*\w/',$string))){
$search = "/\s*".$escapedOperator."\s*/";
$string = preg_replace($search,$operator['symbol'],$string);
}else{
$string=str_replace($operator['symbol'],"",$string);
}
我正在輸出:
title "space before" and text breaks
但是我需要:
title:"space before" and text breaks
如上所述, preg_grep()
需要一個數組作為第二個參數,而不是字符串。 如果您更改:
$string = 'title: "space before" and text breaks';
至:
$string = array('title: "space before" and text breaks');
您的代碼有效,並echo $string[0];
,將輸出title:"space before" and text breaks
如果目標是刪除冒號(:)周圍的空格,那么您是否可以這樣做?
$string = 'title: "space before" and text breaks';
$string = preg_replace('/\s*:\s*/', ":", $string);
echo $string[0];
這還將輸出title:"space before" and text breaks
