请问一个str_replace函数的有关问题
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
即
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>
