I'm using preg_match_all and I want to capture the floating point numbers that do not have a letter following them.
For example
-20.4a 110b 139 31c 10.4
Desired
[0] => Array
(
[0] => 139
[1] => 10.4
)
I've tried was able do to the opposite using this pattern:
/\d+(.\d+)?(?=[a-z])/i
which captures the numbers with letters that you can see in this demo. But I can't figure out how to capture the numbers that have no trailing letters.
我正在使用preg_match_all，我想捕获其后没有字母的浮点数。< / p>
例如
-20.4a 110b 139 31c 10.4
所需
[0] =＆gt; 数组
（
[0] =＆gt; 139
[1] =＆gt; 10.4
）
我试过能做到 使用这种模式相反：
/ \ d +（。\ d +）？（？= [az]）/ i
使用您可以在此演示中看到的字母捕获数字 。 但我无法弄清楚如何捕获没有尾随字母的数字。
