4 个解决方案

#1

You can get image details with

您可以使用获取图像详细信息

$details = get_image_size($filename).

$details[3] will contain the width and height in html format ready for you to use.

$ details [3]将包含html格式的宽度和高度,供您使用。

Could possibly try this

可能试试这个

img src='$filename' style='width:250px; height: 250px'

allows you to strech image to specific size

允许您将图像拉伸到特定大小

to scale you could use

按比例你可以使用

img src='$filename' style='width:auto; height: 250px'

There are a few ways to do this. As you are looping through your images, you want to keep track of the maximum width.

有几种方法可以做到这一点。在循环显示图像时,您需要跟踪最大宽度。

$newImageArray = array();
$maxWidth = 0;
$maxHeight = 0;
$i = 0;
forEach ( $imageArray as $picfile ) {
    $newImageArray[$i]['picFile'] = $picfile;
    $imgsize = get_image_size($picfile);
    $newImageArray[$i]['width'] = $imgsize[0];
    if ( $imgsize[0] > $maxWidth ) {
        $maxWidth = $imgsize[0];
    }
    $newImageArray[$i]['height'] = $imgsize[1];
    if ( $imgsize[1] > $maxHeight ) {
        $maxHeight = $imgsize[1];
    }
    $1++;
}
forEach ( $newImageArray as $i) { ?>
    <img src="<?php echo $picfile; ?>" border="0" width="<?php echo $maxWidth; ?>" height="<?php echo $maxHeight; ?>" align="left" style="border:1px solid black;margin-right:5px;">
<?php
}

Now you shouldn't really be doing this. A CSS based option would work better. You can add a wrapper container with a width on it and set the images to display:block;width:100%; and the images will always fill the space. I will edit with that solution shortly.

现在你不应该真的这样做。基于CSS的选项可以更好地工作。您可以添加一个宽度在其上的包装容器,并将图像设置为display:block; width:100%;并且图像将始终填满空间。我将很快编辑该解决方案。

This will keep the image within a fixed width, and scale the image to fit inside of the box when it is too large.

这将使图像保持固定的宽度,并在图像太大时缩放图像以适合框内部。

HTML:

<div class="imgWrap">
   <img src="http://www.captainangry.com/img/1236647133510anonib.jpg">
</div>

CSS:

.imgWrap {
    width:100px;
    height:100px;
    float:left;
}
.imgWrap img {
    display:block;
    max-width:100%;
}

If you don't want to do any work in PHP then just wrap the image in a div and set overflow:hidden. This assumes that you know the height you want all of your images to be.

如果你不想在PHP中做任何工作,那么只需将图像包装在div中并设置overflow:hidden。这假定您知道所有图像的高度。

<div style="width:<?php echo $imgsize[0]; ?>; height:100px; overflow:hidden; border:1px solid black; margin-right:5px">
    <img src="<?php echo $picfile; ?>" width="<?php echo $imgsize[0]; ?>" height="<?php echo $imgsize[1]; ?>">
</div>
