回复内容:
strstr获取指定字符之后的所有字符串,其中是包含那个指定字符的,求个不包含指定字符的方法
可以这样做(参考)
<code><?php $allString = "I love Shanghai 123456!"; $searchString = "Shanghai"; $newString = strstr($allString, $searchString); $length = strlen($searchString); echo substr($newString, $length); </code></code>
或者
<code><?php $allString = "I love Shanghai 123456!"; $searchString = "Shanghai"; $firstLength = strpos($allString, $searchString); $length = $firstLength + strlen($searchString); echo substr($allString, $length); </code></code>
使用正则匹配:
<code><?php $allString = "I love Chongqing 123456!"; preg_match("/Chongqing(?<right>.*)/", $allString, $matches); print_r($matches);</code>
其中,right只是给匹配的结果命名,最终输出:
<code>Array ( [0] => Chongqing 123456! [right] => 123456! [1] => 123456! )</code>
<code>$str = 'I love guangdong 123456!'; $strDelimiter = 'guangdong'; var_dump(preg_split('/'.preg_quote($strDelimiter,'/').'/',$str)); # 如果确定strDelimiter只出现一次 var_dump(strrev(strstr(strrev($str),strrev($strDelimiter),true))); # 替换 var_dump(preg_replace('/.+?'.preg_quote($strDelimiter,'/').'/','',$str)); </code>
