[SOLVED] Trimming input

[simonp]

Hi,

 

I have some code that grabs information from a source that I can't change:

 

$gamerachievements always returns five entries in the following format:

 

<a href="http://live.xbox.com/en-US/profile/Achievements/ViewAchievementDetails.aspx?tid=%09%5d%3a%60m%2fl4%07%02&compareTo=xxx"><img height="32" width="32" title="Call of Duty 4" alt="" src="http://tiles.xbox.com/tiles/3g/9G/0Wdsb2JgbA9ECgQJGgYfWSpVL2ljb24vMC84MDAwIAABAAAAAP5pD8E=.jpg" /></a>

<a href="http://live.xbox.com/en-US/profile/Achievements/ViewAchievementDetails.aspx?tid=%09%5d%3bhe)j3se4X6z-17&compareTo=xxx"><img height="32" width="32" title="Boom Boom Rocket" alt="" src="http://tiles.xbox.com/tiles/ZP/3f/1Wdsb2JgbA9ECgUAGwEfVlkiL2ljb24vMC84MDAwIAABAAAAAPrw-Xs=.jpg" /></a>

<a href="http://live.xbox.com/en-US/profile/Achievements/ViewAchievementDetails.aspx?tid=%09%5d%3bdh-%01%07&compareTo=xxx"><img height="32" width="32" title="GTA IV" alt="" src="http://tiles.xbox.com/tiles/8x/Us/1Wdsb2JgbA9ECgUMGgQfWSlRL2ljb24vMC84MDAwIAABAAAAAPoDFew=.jpg" /></a>

<a href="http://live.xbox.com/en-US/profile/Achievements/ViewAchievementDetails.aspx?tid=%09%5d%3bdh-o%3fy%03&compareTo=xxx"><img height="32" width="32" title="Bully Scholarship Ed." alt="" src="http://tiles.xbox.com/tiles/x3/MQ/1mdsb2JgbA9ECgUMGgQfVl4iL2ljb24vMC84MDAwIAABAAAAAPk-c9g=.jpg" /></a>

 

. . . but I only want to use four of them (so I want to ditch the last link + image)

 

Is this possible?

 

Cheers

try this

 

<?php
$strContent = <<< EOF

echo implode('</a>',array_splice(preg_split("/<\/a>/",$strContent),0,4));
?>

Thanks Rajiv,

 

I tweaked your code to:

 

$gamerachievements = implode('</a>',array_splice(preg_split("/<\/a>/",$gamerachievements),0,4)) . "</a>";

 

. . . which worked a treat.

 

Cheers!
