php 正则表达式从模式中获取所有 int 或 decimal

Question

Purpose of my code to get all take profit which has int or decimal value. writing pattern of Takeprofit will not same.

Problem:

1. i want $m[3][4] or $m[4][4] as 1.0870 but i got only 0870. i am getting this result when number starts from 1.xxxx. They are conflicting. I can not solve
2. TP-----1.0870 and TP=1.0870 are not detected

My Code:

<?php
$s = 'SS 1.0140 SL 1.0670 TP1 1.0870 TP 1 1.0870 TP 2 1.0870 Takeprofit1 1.0870 Take profit 1 1.0870 TP 1.0870 TP-----1.0870 TP=1.0870 TP1=1.0870 TP Open';

$p = '#\b(TP1|TP 1|TP2|TP 2|TP3|TP 3|TAKE PROFIT 1|TAKE PROFIT 2|TAKE PROFIT 3|TAKEPROFIT 1|TAKEPROFIT 2|TAKEPROFIT 3|TAKEPROFIT\|TP)(.*?)(\bOpen\b|\b(\d+(?:\.\d+)?)\b)\b#i';

preg_match_all($p , $s , $m);

Result of $m:

Array

You may use

'~\b(TAKE ?PROFIT ?(?:[1-3]|\|TP)|TP ?(?:[1-3](?!\.\d))?)\b(.*?)\b(Open|(\d+(?:\.\d+)?))\b~i'

See the regex demo

Details

• \b - word boundary
• (TAKE?PROFIT?(?:[1-3]|\|TP)|TP?(?:[1-3](?.\?\d))?) - Group 1 : TAKE , an optional space, PROFIT , an optional space, then a digit from 1 to 3 or |TP substring, or TP with an optional space after it that is optionally followed with 1 , 2 or 3 that are not followed with . and a digit
• \b - word boundary
• (.*?) - Group 2 : any 0+ chars other than line break chars as few as possible
• \b - word boundary
• (Open|(\d+(?:\.\d+)?)) - Group 3 : Open or Group 4 : 1+ digits followed with an optional sequence of . and 1+ digits
• \b - word boundary.
