下面的实例是利用php 正则替换函数 ereg_replace来把指定的字符替换成我想需要的字符实例,代码如下:
- $num = 'www.phpfensi.com';
- $string = "this string has four words. <br>";
- $string = ereg_replace ('four', $num, $string);
- echo $string;
-
- $num = '49';
- $string = "this string has four words";
- $string = ereg_replace ('four', $num, $string);
- echo $string;
-
- $string ="测试用文字";
- echo "**********$string**********<p>";
- $string = ereg_replace ("^", "<br>", $string);
- $string = ereg_replace ("$", "<br>", $string);
- echo "==========$string==========";
