php读文件(读取文件内含有某字符串的指定行)

文件内容

web=/WmCmUr/WmCmUr?wsdl
audit=/secdit/ws/WmCmUr?wsdl
auth=/app/services/AuthSecService?wsdl

读取含“services”的那一行，且只取等号后的值

/app/services/AuthSecService?wsdl

实现方式：

<?php
	$uriFile = "ConfigFile2.conf";
	if(file_exists($uriFile))
	{
		$lines = @file($uriFile);
		foreach($lines as $lineStr)
		{
			//var_dump($lineStr);
			/**string(24) "web=/WmCmUr/WmCmUr?wsdl"
            string(29) "audit=/secdit/ws/WmCmUr?wsdl"
            string(39) "auth=/app/services/AuthSecService?wsdl" */
            
			if(stripos($lineStr, 'services')!==false)
			{
				var_dump(trim(explode('=', $lineStr)[1]));
			}
		}		
	}
?>

显示结果：
