: This article describes PHP's simple method of determining whether a string contains another string. if you are interested in the PHP Tutorial, refer to it. This example describes how to use PHP to determine whether a string contains another string. We will share this with you for your reference. The details are as follows:
When using PHP to determine whether a string contains a simple substring, we usually use the strpos () or stristr () functions, however, if the position of the string is 0 in the index, that is, at the beginning of the string to be matched, a problem occurs.
Of course, we still have a solution. here is a stupid method, but it is easy to use. it applies to both Chinese and English punctuation.
The code is as follows:
Function checkStr ($ str, $ target) {$ tmpArr = explode ($ str, $ target); // print_r ($ tmpArr); if (count ($ tmpArr)> 1) return true; else return false;} $ result = checkStr ("sdfg", "bsdfsldkfj"); var_dump ($ result );
