php 判断字符串包含指定字符
下面是利用正则表达式来判断字符串包含指定字符的php代码,主要用到了ereg函数来验证:
//实例一,代码如下:
<?php $string="i am abc"; if (ereg ("www.phprm.com", $string)) echo "'abc' is true <p>"; if (ereg ("^abc", $string)) echo "'^abc' is true <p>"; if (ereg ("abc$", $string)) echo "'abc$' is true"; //实例二,代码如下: $string = "this is a test. that is another test."; echo ereg_replace (" is", " was", $string)."<p>"; echo ereg_replace (" is", "<b> is</b>", $string)."<p>"; echo ereg_replace ("test", "<a href=http://www.phprm.com>test</a>", $string);
