请教一个str_replace函数的问题
有个问题还要请教下,比如下面一组数据

00010,00014,0000000023,24,0027,0000

我想去掉这里面的所有的0 , 但是“,”号前面的0不去掉



00010,00014,0000000023,24,0027,0000

这组数据变成

10,14,23,24,27

请问这个该怎么做呢?

------解决方案--------------------
echo preg_replace('/(^|,)0+/', '$1', '00010,00014,0000000023,24,0027,0000');

10,14,23,24,27,

1、str_replace 只能替换固定的字符串,不定的串需要用正则表达式
2、不认为 10,14,23,24,27 这个结果是正确的,因为他丢失了一项
------解决方案--------------------

PHP code

$str    = "00010,00014,0000,000023,24,0027,0000";
echo    trim(preg_replace("/[^,]+,?/e", "intval('\\0') > 0 ? intval('\\0').',' : ''", $str), ',');
//10,14,23,24,27 <div class="clear">
                 
              
              
        
            </div>
