Question

大脑今天不工作 - 任何人都可以给我一个转向的正则表达式：

 {events:{click:"function() { alert('hi'); }"}}}}}

成：

 {events:{click:function() { alert('hi'); }}}}}}

任何其他实例，例如字符串中的这种情况。

如果这有助于扩展我的问题：

到目前为止使用这个：

$replacement = '${1}:';
$json_options = preg_replace('/"(\w+)"\s*:/', $replacement, $json_options);

我转过来了：

string(1051) "{"chart":{"renderTo":"tx_count","defaultSeriesType":"spline"},"credits":{"enabled":false},"series":[{"type":"spline","name":"Transactions Per Day","color":"#4572A7","data":[3,5,3,3,3,6,6,92,2]},{"type":"spline","name":"Value Per Day","yAxis":1,"color":"#89A54E","data":[30,232,172.99,30,160,550,596,2407.96,20]},{"type":"spline","name":"Average Value Per Day","yAxis":2,"color":"#AA4643","data":[10,46.4,57.7,10,53.3,91.7,99.3,26.2,10]}],"legend":{"enabled":true},"xAxis":{"labels":{"rotation":"-45"},"categories":["02\/02\/2011","03\/02\/2011","06\/02\/2011","07\/02\/2011","08\/02\/2011","09\/02\/2011","10\/02\/2011","11\/02\/2011","14\/02\/2011"]},"title":{"text":"Transactions Summary","align":"center","x":0,"y":20},"yAxis":[{"title":{"text":"Transactions","style":{"color":"#4572A7"}}},{"title":{"text":"Value","style":{"color":"#89A54E"}},"opposite":true},{"title":{"text":"Value (Average)","style":{"color":"#AA4643"}},"opposite":true}],"plotOptions":{"series":{"cursor":"pointer","point":{"events":{"click":"function() { alert('hi'); }"}}}}}"

进入这个（这是完美的），

string(947) "{chart:{renderTo:"tx_count",defaultSeriesType:"spline"},credits:{enabled:false},series:[{type:"spline",name:"Transactions Per Day",color:"#4572A7",data:[3,5,3,3,3,6,6,92,2]},{type:"spline",name:"Value Per Day",yAxis:1,color:"#89A54E",data:[30,232,172.99,30,160,550,596,2407.96,20]},{type:"spline",name:"Average Value Per Day",yAxis:2,color:"#AA4643",data:[10,46.4,57.7,10,53.3,91.7,99.3,26.2,10]}],legend:{enabled:true},xAxis:{labels:{rotation:"-45"},categories:["02\/02\/2011","03\/02\/2011","06\/02\/2011","07\/02\/2011","08\/02\/2011","09\/02\/2011","10\/02\/2011","11\/02\/2011","14\/02\/2011"]},title:{text:"Transactions Summary",align:"center",x:0,y:20},yAxis:[{title:{text:"Transactions",style:{color:"#4572A7"}}},{title:{text:"Value",style:{color:"#89A54E"}},opposite:true},{title:{text:"Value (Average)",style:{color:"#AA4643"}},opposite:true}],plotOptions:{series:{cursor:"pointer",point:{events:{click:"function() { alert('hi'); }"}}}}}"

现在我需要删除可能在字符串中的任何函数（）{... stuff ...}的双引号。

Answer 1

你可以$string = str_replace('"', "", $string);，在这个特定的例子中不需要正则表达式。

或者试试这个：

$string = str_replace(array('"function()','}"}'), array('function()', '}}'), $string);

Answer 2

这对我有用：

<?php preg_replace('/"(function\s*?\(\)\s*?{.*?})"/', "$1", $string); ?>

删除“function（）{...}”周围的双引号
