如何选择以“< img"开头的行带有IF语句 [英] How to select rows that start with "<img" with an IF statement

问题描述

我在表中有两列Entry和text_image.循环查看数组中的所有行时，我可以获得结果，但是我希望它向具有以img开头的文本的行添加/images.这是为了将具有"img"(意味着该行中的文本)的行定向到正确的文件夹.它可能需要进一步的解释来说明原因，但我不会介入.

I have two columns, Entry and text_image, in a table. When looping to see all the rows in an array, I can get the results, but I want it to add /images to the rows that have text starting with img. This is to direct the rows that have "img" (meaning the text within the row) to the correct folder. It might need further explanation to illustrate why but I wont get into it.

while($row = mysql_fetch_array( $result3 )) {
    echo "<div class=\'entry\'>";
    (I want to add an echo "/images" before the rows that start with "img")

    echo $row[\'text_image\'];
    echo "</div>";
}

提前谢谢

推荐答案

$images = (substr($row['text_image'], 0, 3) == 'img') ? "/images" : "";
echo $images . $row['text_image'];

这将检查$row['text_image']的前3个字母是否为img，然后将$images设置为/images，否则将其留空.它将在循环中的每次更新.

This will check if the first 3 letters of $row['text_image'] are img then set $images to /images else it will leave it empty. This will update each time within the loop.
