如何通过php中的正则表达式多次替换分隔符之间的字符串 [英] How to replace string between delimiters more than once by regular expression in php

问题描述

我想替换多个匹配的特定前缀和后缀分隔符之间的动态字符串值。通过在php中使用preg_replace（）方法，我可以使用以下模式在分隔符之间设置值。但它只适用于最后一场比赛。

_________________________________________________________________________________________

preg_replace（＃（。*）$ delimit（。*？）$ delimit（。*）＃is， $ 1 $ attr = $ delimit $ inject $ delimit $ 3，$ contents）;

_________________________________________________________________________________________

请帮帮我，我该怎样才能做到这一点。以及如何处理分隔符之间不可预测的空白



********* {delimiter} {old string} {delimiter} ***** ******* {delimiter} {old string} {delimiter} *****************

to

********* {delimiter} {new string} {delimiter} *********** {delimiter} {new string} {delimiter} ******* **********

请帮帮我。谢谢。

_________________________________________________________________________________________
Please help me, how can I achieve this. and how to handle unpredictable white space between delimiter

"********* {delimiter} {old string} {delimiter}************{delimiter} {old string} {delimiter} *****************"
to
"*********{delimiter} {new string} {delimiter}***********{delimiter} {new string} {delimiter}*****************"
