如果尾部包含-1245，我如何剥离下面的字符串？
'product name with color-0250' -> 'product name with color'
'product name with size-300' -> 'product name with size'
'product name with something-11200' -> 'product name with something'
我想要的只是产品的名称。
您可以使用explode()并通过'-'进行分解，假定产品名称永远不会包含'-'。
$strProductName = 'product name with color-0250';
$arrParts = explode('-',$strProductName);
echo $arrParts[0]; // Returns: product name with color
您也可以使用带有preg_match或preg_replace的正则表达式。使用preg-replace可以捕获产品名称，即使它包含"-"
echo preg_replace('/('-[0-9]+)$/i', '', 'product name with color-0250');
// Returns: product name with color
preg_replace 的另一个变体
preg_replace("/(.*)-('d+)$/", "$1", "product name with color-0250")
或者您可以使用strrpos():
$str = 'product name with color-0250';
$pos = strrpos($str, '-');
echo substr($str, 0, $pos); //Returns: product name with color
使用explode()选项。
$test = 'product name with color-0250';
$hi = explode('-',$test);
var_dump($hi[0]); //will give 'product name with color'
