假设我有一个字符串
$string = 'this is my gal_s, not my 1_s not 2_s not 3_s';
$find = '_s';
$replace = '';
我想返回
"this is my gal_s, not my 1 not 2 not 3"
所以单词gal_s
不受影响
这可能吗?
你可以像这样使用preg_replace:
$repl = preg_replace('/(?<!'bgal)_s/', '', $str);

@anubhva answer is good also alternate try
$string = 'this is my gal_s, not my 1_s not 2_s not 3_s';
$find = '_s';
$replace = '';
$arr = explode(',', $string);
$arr[1] = str_replace('_s', '', $arr[1]);
echo $string = implode($arr);
