I just want to know, what are the replacements of the preg_replace function.
能否做到这一点?
For Example:
$string = "test text 12345";
$string = mb_ereg_replace( #text|test# , $1-test2 ,$string);
我想知道,“案文”和“测试”是吻合的? 或者说,必须做事吗?

可以通过参考将一个计数变量转换成预选,从而将出现的配对/替代物数目退回。
见。
$string = "test text 12345";
$count = 0;
$string = preg_replace( text , test2 , $string, -1, $count);
echo $count; // 1
......你可以使用<代码>preg_replace_questback(),这样,你就能够按要求履行习惯职能。 之后,你将能够“看到”匹配,并取代你想要的。
如果这不是你试图发现的一种模式,而仅仅是在扼杀中的案文,那么你可以使用<条码>。
$findthis = "Apple";
$container = "Apple Orange Kiwi";
if (strstr($container,$findthis))
echo $findthis. is present ;
else
echo Not found ;
}
使用preg_match()
进行测试,然后使用preg_replace(<>>>/code>,如果你希望与
preg_replace_questback(<>
产生问题,这也是一种解决办法。
text
→ test2
) and在该案中,我只使用str_replace(
取代,随后是strcmp(
,以说明扼杀装置是否改变(即更换了)。
Try this:
$string = test text 12345 ;
if ($string != ($replaced = preg_replace( /text/ , test2 , $string))) {
echo text was replaced ;
}
Though if you don t really need preg_replace, you should use strstr or stristr.
